Heat and Male Fertility

Heat is among the top causes of reduced fertility in men. The sources of heat to the family jewels range from tighty whities to laptops to fevers and anatomy issues. All of these things can impact your fertility. Are you cooking your balls?

How does heat affect fertility?

As mentioned in our article on sperm production, sperm are finely crafted little baby making machines. They require a precise environment — 4 degrees cooler than body temperature. For this reason, testicles were fitted with a muscle called the cremaster muscle, which contracts to pull the testicles close to the body when they get too cold and relaxes to let them hang lower when it gets warm. If sperm are exposed to elevated temperatures, they begin to die. This will show up on a semen analysis as reduced motility. If the exposure to heat is prolonged, it can affect sperm production processes, causing the body to produce fewer sperm, many of which may be abnormally shaped. On a semen analysis, this will show up as reduced sperm count and abnormal morphology (often accompanied by reduced motility).

Most common sources of heat

Because it takes 70 days to sperm to mature, it can take up to 3 months to recover sperm counts after a high heat exposure (such as having a fever). Please be sure to indicate to a doctor any possible exposures to heat that may affect sperm count if going in for a fertility workup. Heat can come from external sources like hottubs and laptops, or internal sources like spiking a fever. Here is a list of some of the most common offenders:


  • Cooking
  • Grilling
  • Motorcycles
  • Hottubs
  • Saunas
  • Laptops
  • Cell phones
  • Tight-fitting clothing
  • Cycling

Don’t Cook Your Balls!

Here are a few tips to help you maximize your fertility by keeping your boys cool and your troops happy.

Take Breaks : Brief exposures to heat are ok as long as you get up, move around, and let the boys cool off. If you are watching TV curled up under a warm blanket, typing with a laptop on your lap, or taking a dip in a hot tub, make sure to have a cool-off break. If you work in a hot environment, try to take extra trips to the water cooler. (You should be getting hydration anyways). Chef Ramsey discovered that all the time around hot ovens had impacted his fertility, and began a campaign to improve fertility safety for chefs (Read more).

Watch what you wear: This starts with your underwear. Make sure its loose enough to let your boys breath. This applies to your jeans too. Again if you have occupational exposure to heat, investigate options for clothing that deflects heat.

Stay cool in the summer: Studies have shown that there is a natural decline in sperm count during the summer due to increased temperatures. Dips in the pool, time in air conditioning, or even a solid breeze can do a lot to keep your fertility up.

Ice your balls: Sounds awful but could be an effective way to reduce heat in cases of fever or even varicoceles before treatment. We first heard about this idea from the guys behind snowballs. More research is needed to see if this is an effective approach, but it doesn’t hurt to try.

Lose weight: Never would have guessed it, but it is actually possible to gain a layer of fat in the scrotum which acts as a nice cozy blanket over the testicle, raising the temperature ever so slightly. Often enough to mess with sperm quality. Fortunately, when people lose weight, they most frequently lose it in out of the way places like fingers, wrists, and feet (I’m going to guess that balls make this list) before taking off the spare tire. So you might not need to lose a ton of pounds to notice a difference in your fertility.

Visit a urologist: Get evaluated to find out if you have a varicocele or other physiological abnormality that contributes to over-heating your testicles. Corrective surgeries are often out-patient procedures and have a high success rate.

        Hi doctor,

        I would like to know the reason for unbalanced testicles in my body. Almost a 1.6 years ago , I started feeling discomfort in between the centre point of scoratum(mid in lower bottom of testicle).Then my right side testicle started hang lower than left side testicle. I met some an urogologist in initially and they investigated by normal procedure…and confirmed no issues with testicles. But I was feeling some discomfort when I’m sitting.

        Then again I have checked another urologist and had done the ultrasound testing..They confirmed my right side testicle slight bigger than left side testicle.and no other issues found(no vericocele,hydrocele). But I again asked the urologist to clarify further,why I have discomfort and why there is slight change in my right side testicle to hang lower.

        He answered one of your muscle might loosen somewhere.so that may caused the reason hanging lower…. We cannot do anything further… Asked me to use underwear tightly…

        After 1 passed,now Recently I started to gym n I could see my pennis started falling right side instead of being straight. Even in 100 % erection ,it completely turning into right side..

        I understand my right side testicle handing lower on right side,it also pulling my pennis to turn right side….

        I would like to know what might be the problem for this…..Help me

          It sounds like you have two potentially separate issues.
          The 1st is that your testicle on one side is slightly larger and hanging a little lower causing discomfort. There isn’t much doctors can do about this and their recommendation is to wear more support. This should help… have you tried it?

          The 2nd issues is the penis bending. This might be the begining of a condition called Peyronies. Over time some men experience a bend in the penis that can be uncomfortable during an erection. I think there are various therapy techniques to help straighten it. It depends on how severe it is. Sometimes it will go away on its own.

          Hope this helps.

        It seems pretty normal. Your body is telling you that your testicles don’t want to be that cold. Here’s an article on how testicles respond to cold temperatures. Is there a reason you are going into water this cold? Is it a normal occurrence? Does pain last long after exposure to the cold? Do they hurt any other time?

      Yes! It definitely could be. Luckily heat exposure like this doesn’t do any type of permanent damage. There are a few things he can do.

      1. Take breaks. Get away from the heat for 5-10 minutes at least once an hour and preferably every half hour.
      2. There are underwear that have gel packs for cooling the testicle that he could wear to work. They come with something like 4 ice packs that are changeable so he could keep them in a little cooler and change them out throughout the day. It’s a little ridiculous but I’ve seen it work for a lot of people

      Also, as a welder, he might be exposed to some nasty chemicals which could be hurting things. Increasing the amount of antioxidents in his diet would not be the worst thing in the world. He could take our risk assessment for a complete list of things that could impact his fertility.

      Sperm take about 72 days to mature, so implementing changes will take a few months to show an effect, but depending on severity of the heat source I’ve seen men that have doubled and tripled sperm count by eliminating heat.

      Good luck.

    Hello everyone, i am here to share my testimony on how i conceived my baby. I have been married to my husband for 3 years without no child. We have been to the doctor and it was confirmed that the both of us are in good condition. I had problems with my in-laws because of the child issue. I was introduced to this sorceress by a friend who lives here in canada. I contacted her and explained my problems to her. She told me all that is required and i did it accordingly. I was very surprise to test positive after 2 weeks of contacting her. I gave birth to my baby boy 4 months ago and i am a very happy woman and a living testimony of this good work. Anyone who needs her help should contact her through (mamajajasorceress@yahoo.com) and you will also testify to her good work.

          You do not need to stop bathing in boiled water. Sperm do not like hot water but if you are not trying to have a child right now it is not a big deal. If you get married and try to make a child. If it takes a long time for your wife to fall pregnant, you will want to make the water less hot.

          Other things you can do to increase sperm count include: eat healthy food, get exercise, sleep well, do not drink to much alcohol or smoke cigarettes.

          Varicoceles tend not to interfere with urination. They are more likely to cause discomfort after long periods of standing (when they are larger) and can cause issues with fertility as they heat up the scrotum, increase pressure and decrease blood flow. Frequent urination is more commonly associated with prostate issues and diabetes or simply drinking lots of water.

          Is this a new thing or has it always been this way? How much water do you drink a day?

      If you feel like your scrotum is too hot during sex and would like to cool it down. Some men do specifically cool testicles at specific times. The best way I’ve seen to do this is a pair of underwear called snowballs with gel packs inside that will cool them down. You could also get old fashioned and use a sack of peas 🙂

      Have you had a semen analysis?

      You don’t need to have them cool when having sex. It is more important to have them cool throughout the day and not let them get overheated.

      Some good ways to make sure you balls stay cool are

      1. take cooler showers — hot water is the fastest way to warm your body. So using cooler water when taking showers will help you not get too hot
      2. try snowballs – these are underwear with nice cooling packs inside
      3. Don’t sit for long periods. When you are sitting, your balls get warmed up by your body. When you are standing they are able to hang down and allow air to cool them.
      4. Avoid hot things – hot rooms, ovens, seat warmers, grills, hot tubs, etc.

        It sounds like you might have a slight infection. It’s not a terribly big deal but it is important to go to the doctor to get it checked out. if not, the pain may get worse. Most infections are easy to treat with antibiotics.

        It’s important to keep your balls healthy.

      Premature Ejaculation is a fairly complex issue. There are many theories about the cause, but most of them have not been proven by scientific studies.

      Clinically defined, premature ejaculation occurs when a man ejaculates within 1 minutes consistently for years and years. The normal range is between 2 – 10 minutes and average is about 4-6 minutes after penetration. Almost all men wish they would last longer.

      Some tips that seem work well include:

      Starting and stopping: Stop moving before ejaculating, then start again and when it feel like you might ejaculate
      Kegel Exercises: Squeezing the muscles that control your pee stream will give you greater control of your ejaculation
      Ejaculate before sex: 2nd ejaculation usually takes longer. If you ejaculate prior to sex (or earlier in the day) then you may be able to last longer
      Use a condom or two to reduce the sensitivity
      Take it slow: slowing down the motion can help you to last longer.

Is it tender to the touch?

    hello months ago i started having a lot of pain on one of my testicles i checked myself and felt a ball and when i would touch the ball i would get so much pain. So i went to the hospital and got an ultra sound and i was told it wasn’t cancer that it was a cyst and i have a varicose vein. The pain was much less within a few days i still get pains and the pain went to the head of the penis i sometimes feel strong pinches on the testicle and pulsing on both the head of the penis and the testicle. I went to the urologist and i got some blood work done and urine test done, i was told that everything was fine to just keep checking myself and that if i feel something abnormal to go back and as in for the pain to just apply something warm on the genitals. I keep getting pains and they don’t seem to go away. It has not only affected my physically since i go to the gym a lot but also has affected me morally. I have no type of motivation for anything anymore when im in pain most of the time now. what can i do?

      Apologies for my delay in responding. I’ve been buried in comments and working hard to respond to everyone.

      Sorry to hear about all your pain. Chronic testicular pain impacts many men. Your case sounds very similar to what many men experience. It can be a very frustrating problem for both men and their doctors.

      How long have you had the pain? Does it occur all the time or just after lots of activity / standing up?

      I met some incredible doctors in florida from the PUR clinic that do remarkable work on testicular pain. Call them for a phone consultation and tell them you found them on Don’t cook your balls. They should be able to point you in the right direction. Here is a recent interview I did with Dr. Jamin on how to treat testicular pain.

      this is called chronic orchalgia or chronic testicular pain. Generally a mild varicocele won’t cause persistent pain (usually they hurt after long periods of standing) But sometimes the nerves flare up and continue to feel pain for not much reason. You can read more to see if you might have other causes of testicular pain in this article I wrote.

      You can also watch some interviews that I did with leading doctors that treat testicular pain.

      You should visit a doctor to be checked for an infection. Lumps on the penis are not normal and you should get it checked out by a doctor.
      If you find out that it is an infection, you should tell the girl what it is so that she can also go to the doctor.

      The nerves that connect your intestine and kidneys are also connected to your testicles. Sometimes pain in one of those places can lead to testicular pain. Doctors call this referred pain. You can read more about it in our article about testicular pain.

      Refraining from ejaculation can cause a build up of pressure that can lead to discomfort. Often this goes away on its own.

      I imagine that in your case, the pain is mostly coming from some issues in your intestines that are irritating the nerves in your testicles. I might discuss this matter with your doctor.

          It is a good idea to get a semen analysis so you can see how bad it is, especially if you are trying to conceive. Many men with varicoceles do not have any impact on sperm. Most doctors will not do surgery to fix a varicocele unless it is causing significant pain or reducing sperm health.

          If you do not get negative results on the semen analysis, then the varicocele will be no problem to you.

          If you have a negative semen analysis result, there are things that you can do to improve your fertility with a varicocele. You can get surgery to repair the varicocele, you can take extra vitamins and cool your testicles and you can try chinese medicine and acupuncture.

          Does your varicocele hurt? Are you currently trying to conceive?

            I think it’s a good time to get a semen analysis just to see where you stand. If you find out that your sperm are good, then you can feel relieved. If you find out that your sperm are impacted then you can figure out if you would like to get a surgery to remove it. It takes about 6 months for sperm to recover after varicocele surgery. So you will want to do it before you start trying to conceive.

            One thing to know about varicoceles is that they tend to get worse with time. If the pain or irritation continue to get worse, you may think about doing something about it.

      Painful intercourse for women can come from a number of factors including tight vaginal muscles, poor lubrication, insufficient arousal, various types of infections or medical conditions can also cause pain during intercourse. She may want to visit her ob-gyn to discuss issues.

      It might be a good idea for you to visit a doctor for a check up. If you do have an infection, the doctor would be able to prescribe some medication to fix it.
      A semen analysis is a relatively quick way to see if you have done any damage to your testicles.

    Hi, thanks for this info. I am curious if you have any detailed info on heat effect on sperm production – for example if I (or anyone) was to take a long hot tub would the sperm be limited for the next 74 days? Also, you’ve mentioned some hot is ok, but not prolonged hot: is there a threshold to watch out for? Could some amount of heating be ameliorated by cooling the balls (snowballs etc) or is it a situation more like my first question where significant heating affects all sperm in the queue?

    Thanks much, my wife and I are thinking of getting pregnant and I’ve a difficult time finding this level of detail.

    • Sara SDx
      Sara SDx January 8, 2016 at 4:58 pm - Reply

      This level of detail is tricky because it is hard to study and fully understand. Scientists do not quite understand the effects on heat and sperm. There are a couple of things going on — heat can impact both sperm count and sperm health.

      So, it takes 74ish days to make a sperm. If you were exposed to heat today. Your germ cells might get overheated and not start the process of making new sperm. If tomorrow it were cool, then they would and the drop in count wouldn’t really be noticable. They do see, however, in cases were someone has a high fever over the course of a couple days that the semen analysis can show up as 0 sperm temporarily. So it is possible to knock production out so hard that it completely wipes production temporarily.

      Part of the equation is how hot is hot? A fever of 101 is quite different than a fever of 104. Some with hot tubs. A few degrees can make a big difference.

      The other side of the equation is the sperm health (motility and morphology) Heat can cause sperm that exist in the pipeline to die (become immotile) or sperm that are developing to develop abnormally (have poor morphology)

      My recommendation if you are trying to conceive is to try to avoid extremes. Don’t stay too long in the hot tub. If you have control of the temperature, turn it down just a little.

      Is your concern primarily about hot tub use or do you have some other form of heat that you are concerned about?

      Also. another thought is what is your baseline? — if you are starting from a high point (like 100-200 million sperm) some heat wouldn’t be the end of the world cause you have plenty. If you are starting out with a lower count (like 30 or 40 million) heat would matter more. You could consider getting a baseline semen analysis done to see where you are at and how careful you would need to be. 🙂

      You might want to have her discuss the issue with a gynecologist.

      Testicles are equipped with a muscle known as the cremaster that helps ensure that they don’t get too cold or too hot. When exposed to warm temperature, the cremaster relaxes and lets the testicle hang lower to help try to cool them off. It is a natural part of biology that can help protect sperm from damage. If the temperature is too hot, sperm can have a reduced motility or bad shape. If heat exposure is over a long period of time, it can reduce your sperm count.

      It is not likely that a minor burn would cause permanent damage.

      6 months is not too long to be trying. It can take up to a year for a healthy fully fertile couple to conceive a baby. If you are concerned about your fertility a sperm test is not very difficult and can give you good feedback about how healthy your sperm are. You can read about sperm testing in this article.

      You could also take our risk assessment to see if there are other things that could be risk factors that may impact your fertility.

      You have no reason to be afraid. When testicles are exposed to cold water, they have a reflex that pull them into the body to keep them from getting to cold. If you want to learn more about it, you can read this article on the cremaster muscle.

      Cold water should not have an impact on your fertility. Testicles are equipped with muscles that help them respond to changes in temperature called the cremaster and the dartos facia. These muscles work together to help your testicles maintain a good temperature for sperm.

      No reason to worry. You should be fine.

    Alright this one might be weird, but I am a 16 yo guy who wrestles. And because i wrestle, i have to cut weight, so a few times in the past I have layered on 3 pairs of underwear, a lot of shorts and a lot of sweat pants + a bunch of shirts and jackets, and i took a trip to the sauna to sweet a lot. I was actually on my way to do it again and i just had the thought that this might affect my balls. which reading this i think it can, I have done this i think twice before, one time i went for 15 minutes, cooled off a bit even though i didnt expose my balls to anything cool, i just stripped down to the bottom layer. and then went back again for another 15. then the other time i went for about 10-15 minutes and then left. and im about to go again, and i dont think that ill stay longer than 15 minutes. but now that im reading this, I obviously wont go again. my balls never hurt or feel over heated, even when i am really hot, even though i think they felt hot the last time i went to the sauna. But i cant recall anytime they have felt hot besides that. And during the summer i work in a pizza place which gets hot, basically im saying that I get really hot often without my balls feeling hot. So basically I am just really affraid that I might have affected my future when i was so young and stupid 🙁 is there any possibility that i have axed my chance of having children? my semen looks like it has sperm in it, but I also barely know anything except what i have learned in biology class.

      Hi Jacob
      Thanks for your comment. First, I’d like to say unless the temperatures are maintained for days or weeks, the damage to sperm is usually temporary. So, it is only hurting the sperm that you are making right now. Even then, each person’s body is different and how heat impacts your sperm is different than how it would impact another guy’s sperm. It’s just something that you need to think about if you are actively trying to have kids.

      Wrestling and working an after school job are great things for a guy your age to be doing and are teaching you great lessons for becoming a dad someday.

      It is a good idea to make sure that you take care of yourself. A more dangerous side effect of dropping water weight quickly is dehydration which can have some long term effects on your body. So while you do what you got to do to make weight, don’t get so intense about it that you hurt yourself.

      The biggest things that can impact your future fatherhood from being an athlete are:

      1. Getting injured. Shots to the nuts are usually not a big deal but they are sensitive organs and if they get hit the right way or twisted, they can get injured.

      2. performance enhancers — do research on any type of supplement you might use for lifting to make sure that it won’t have negative impacts on your testosterone cycle.

      Other than that, keep living healthy — stay clear of cigarettes and drinking too hard or too much in college. protect yourself from STDs and try to eat relatively healthy and you should be fine when the time comes.

      Hope this makes you feel a little better.

      Have you been re-tested for Staph since the antibiotics? We need to find out if you have a methicillin resistant form of Staph. It could be that the infection is treated and you have residual inflammation that is causing issues. Inflammation would be treated with different drugs. Too many different types of antibiotics can cause problems so it is really important to re-tested with a new culture and see if they can determine the strain.

      In the meantime, you should be able to handle pain with higher dose ibuprofen. That should reduce heat and pain. You can also consider icing or cooling down there to try to find relief.

      Let me know. We can find a solution.

      Hard to tell. It depends on how hot the testicles got and for what period of time. It also depends what his baseline numbers are. If he is normally on the high end, knocking down counts temporarily wouldn’t terribly impact chances, while if he was average or slightly low, it could have a more dramatic effect.

      The best course forward is to try to avoid any additional heat exposure. You might have him take a pre-natal vitamin… it could give the sperm that are there a little boost (kind of like taking vitamin C when you get sick — it doesn’t fully stop you from getting sick but it can help on the margins).

      Hope this is helpful. Wish I had more definitive answers.

      Wow. You guys have been through a lot.

      How long ago was the fire? Were any of his man parts impacted by the fire? Has he had a semen analysis?

      Generally, unless burns directly impacted the parts in question, he is still likely to have the ability to father a child even in cases when sexual function is impacted. Since you are going to need to go the route of IVF, I would be very surprised if there weren’t a few good sperm that could be used. 100,000 or more should be enough for classic IVF. ICSI only needs a few. If sperm aren’t present in the ejaculate, they can be retrieved from the testicle directly.

      1st step is a semen analysis to see where you stand, but I think there is plenty of hope for you guys to have a baby together.

      I don’t recognize the medications. Inflammation is different than infection. Sometimes when an infection is treated, there is inflammation that can cause pain and heat. I would recommend taking ibuprofin. This is a common medication for headaches and should be available in the drugstore. Take the full dose for like 2 weeks and see if it helps.

      Its totally normal. Is it warm enough to impact sperm? hard to tell from the description. I would recommend that he try to stand up and walk around for 5-10 minutes every hour or so. I know this can be hard to do when you are focused on work but it takes about 1 hour for the scrotum to heat up to body temperature, which can impact sperm.

      Does it feel hot when he releases inside you?

      Generally, sperm will feel hot on the skin because your skin is cooler than the fluid coming out. Generally it is not because of elevated temperature of the sperm.

      There is very little you can do to optimize chances for a boy vs a girl. I have 3 boys and would love to have a daughter so I’ve done some investigation. Thy only difference between boy and girl sperm are that the girl sperm carry an extra X chromosome. X chromosomes are larger than Y, therefore girl sperm are very slightly heaver than boys. Boy sperm have an advantage to swim fast. The best way to try to optimize is to have sex super close to ovulation and hope that a boy sperm makes it first. You can’t really boost chances that much…

      Hope this helps.

      Let me know if you have any other questions.

    Hi Sara,

    My question for you is does hot showers on a daily basis affect sperm count? I will take hot showers every morning for about 20 minutes

    My wife and I are working on getting pregnant and I have already gone in for for a sperm analysis once and the results were not good. However in the past when I went to a sperm bank, the numbers of sperm count were excessive (good old college days). Not sure if this recent trip was a fluke

    Between the period of my last sperm analysis I have changed up a few factors which included getting away from boxer briefs and going strictly boxers, keeping my balls cool at times, improving diet (no weight or excess fat anywhere, just poor food choices), staying hydrated, etc.

    Any other suggestions? Also, how much does coffee play into the sperm equation?

    • Sara SDx
      Sara SDx March 3, 2016 at 6:38 pm - Reply

      As long as the showers are not overly hot, you should be fine. If they turn your skin red, the water might be a little too hot and you might want to either shorten shower time to 10 min or so or reduce temperature so it’s not quite so scalding. If it’s just normal warm / hot water, 20 min should be ok.

      Coffee is a stimulant for sperm too. Studies show that if you add caffine directly to semen, sperm will kind of wig out and get jittery. There isn’t much research on caffeine consumption and fertility outcomes for men. Overall, my take is keep it moderate and you should be ok. If you are drinking lots of coffee, try to cut back a little.

      Sperm parameters can vary quite a bit from test to test for a couple of reasons. 1. Abstinance period plays a big role. if you abstain 2 days for 1 test and 5 for the next, things might be pretty differnt. 2. small things in life — like heat — can cause pretty big swings in sperm. So a 1 time exposure to something can knock you down for a few days. 3. semen analysis vary quite a bit due to the level of care and skill of the technician performing them. In an absolute best case, you are looking at a 10-20% difference if the same sample was divided and run by 2 different people. So a count of 10 million could really be 8-12. When you add natural varience to varience in testing you can get some pretty big swings.

      My best suggestion is keep up with what you are doing. Living well and avoiding heat is the best you can do. Vegetables are critical for sperm health. You need to get a minimal amount of folate to enable DNA replication. Other vitamins and nutrients play a big role in supporting sperm production and sperm health. Do some more healthy living and go back in for another analysis.

      If test #2 comes back low, I would recommend getting checked for a varicocele. They are known to cause issues and grow over time (so you develop them as you get older and they get worse as time goes by).

      Do you have numbers, what is your sperm count?

      Weight can cause a problem, especially if you are getting a large belly. Can you tell me your BMI?

      Did you take our test? It can give you advice on things to do to improve your sperm count.
      Squeezing your testis shouldn’t be an issue unless you are causing pain.

      There are lots of causes for testicles overheating. Most of them time it is caused by external heat like sitting too long or using a hot tub. Sometimes internal body temperature gets elevated, like when someone gets a fever. Testicles can also get overheated in men that are a little overweight. Body fat can act like a blanket and warm the testicle. Occasionally, testicles can have an infection or injury that causes them to swell, hurt or feel warm to the touch. In these cases, it is important to get them looked at by a doctor to see what type of treatment would be best. Sometimes they will prescribe antibiotics if there is an infection present. Does your boyfriend have pain down there at all or any other symptoms other than heat?

    I am a 25 year old male. I have an overactive cremaster reflex. My testes (both) goes up into my body when cold, during sex and even in a stressful situation. It got worse over the years and I consulted an Urologist. I made the discussion to cut of my cremaster muscle. The doctor cut below my abdominal and below my testes.

    The operation was successful and it was amazing to feel my testes hanging low again. Five days after the operation I climbed into a cold bath and the testes did not go up. The same day I also ejaculated with no pain en with the testes staying low. The volume of sperm increased as well.

    About ten days after the operation my testes started to move up again. It doesn’t go up into my body anymore, but it goes up.

    The volume of sperm is low again compared to the few times my testes did not move up.

    I would like an second opinion before I consult my urologist again. Is it possible for the cremaster muscle to grow back on such short time after the operation after being cut at two places ? Is that the only muscle for the testes moving up or does the scrotum retracts as well with another muscle? Last question, does the volume of sperm have any correlation with the cremaster muscle?

    • Sara SDx
      Sara SDx March 21, 2016 at 3:40 pm - Reply

      The testes should go up sometimes. Going into the body is not good, but there should be a normal amount of up and down. Here’s a more detailed article that I wrote about cremaster. There is a secondard muscle, called the dartos facia which doesn’t move the testicle but controls the skin on the scrotum to help regulate temperature.

      I doubt the cremaster re-grew after operation, my guess is that the operation limited the movement but didn’t completely prevent it from working at all. In the first few days the body was recovering and now it is at a normal level.

      Semen volume is mostly determined by frequency of ejaculation. Temperature of the scrotum doesn’t impact it. It does impact sperm, but I don’t think you are actually looking at sperm under a microscope, correct?

      Do you have any pain? What is your main concern now?

  56. Barend March 22, 2016 at 1:45 pm - Reply

    Thank you so much for you response!

    No, I am not looking at sperm under a microscope. I apologize, I did not mean to say sperm, but semen.

    Today is day 18 after the operation. Yes I do have some pain, but it is getting better every day. I can walk normal and have no discomfort when seated or horizontal. You answered exactly what I wanted to know. My concern was that the cremaster grew back, due to the fact that the first 5 days no movement of the scrotum and testes occurred, but thereafter the testes (scrotum) moved up when cold or when I ejaculte. My other concern was that the contraction influence my semen volume. According to literature there is a 5% possibility of the cremaster growing back and that was my concern, the testes would move up into my body again.

    I presume it is the dartos facia contracting my scrotum at the moment, rather than my cremaster as you explained above. My scrotum shrinks to about half the volume it normally is (for a lack of a better explanation) and this happens multiple times a day. It occurs when I am cold, have to urinate, ejaculate or just randomly.

    Does this mean that my datros facia is overactive? Just like my cremater was before the operation?
    If my datros facia is overactive, what would your Advice be, if any?

    Thank you again.

      I am not too familiar with the procedure that you underwent, so I can’t comment on whether the cremaster grew back. If you would like to send me the name of the procedure, I can review literature on recovery and see if there is indications for cremaster re-growth.

      Dartos typically controls scrotal skin but I do believe it can help with testicular movement. I haven’t much thought of it as separate from the cremaster.

      It is important to have some ability for the testicles to move closer to the body. They do so to protect themselves from injury. You don’t want them always hanging low or you could really hurt yourself. The contraction has nothing to do with semen volume. Semen is made by seminal vesticles up near the prostate. Semen volume is primarily determined by ejaculation frequency. Secondarily, prostate health, diet and various medications can impact semen volume and consistency.

      If you want to send me additional information about the procedure, I’d be happy to do some research and give you additional thoughts.

    Hi, my wife and I have been trying to get pregnant for nine months. No success. I own a sauna and a hot tub and was using the sauna 1-2 times a week and the hot tub 4-5.

    Since I learned about heat and its effect on the nuts I cut sauna and hot tub usage down to 1 times a week. But my wife wants me to stop sauna and hot tub useage completely unti she gets pregnant,

    I am looking to compromise. My question is would it work to wrap my balls in ice while I sauna (or tub)? Would this protect them from the heat? I have rigged up an athletic cup that can hold crushed ice. It fits snug to the groin. Would this work

      This the kind of funny debates that happen when you are trying to conceive… made me smile a little. I salute your creativity.

      I can say that regular heat exposure like that will definitely impact sperm health and potentially count and could make conception take longer, so your wife’s concerns are well founded and backed by science. There was a study where normal men used a hot tub everyday and counts dropped to almost 0. It’s different from man to man, but the impacts are def real.

      You compromise sounds fair. I’m not sure how the ice cup will work in the hot tub, but if you can manage to keep your buddies completely cool throughout the heated experience that should protect sperm.
      It is fair to let you know that sperm take about 3 months to recover from heat exposure — so if you have impacted sperm production through heat exposure you might be 3 months away from getting your count back up.

      Other things that can help is lowering the temperature of the hot tub and staying in less than 15 minutes at a time.

      If you are interested in a way to find out what your sperm count currently is and and monitor it over the next few months, I am working on an experimental kit / app that could help. If you are interested — email me: snaab@sandstonedx.com I offer it, just cause it seems like it could help settle some marital debates and save you both a bit of heartache.

      Good luck bud.

        Well, I tried the ice jock in the sauna and it works like a charm! My balls think it is -20 out and stay really cold while the rest of my body enjoys the sauna. I put ice cubes in the blender and fill the athletic cup with the shavings. I actually have to wear the jock and cup outside of my swim trunks to prevent freezer burn. Now I just need to figure out something for the hot tub!

      Do you masturbate a lot? Do you use lubricants?
      What do you mean by not having proper ejaculation?
      Has it gotten worse or better since you first noticed it?

      If you are not trying to conceive right now, I wouldn’t be too worried. Heat doesn’t typically cause permanent fertility damage unless temperatures are sustained over very long periods of time. (For example, undecended testicles are maintained at body temperature for weeks or months or years or when someone has a super high fever that doesn’t go away for a while.) Hot tubs, saunas, etc will cause a temporary drop in sperm count that will last something in the neighborhood of 2-6 months depending on how frequent heat exposure is and how high temperatures get.

      In your case, I would imagine that stickiness could elevate temperatures, especially if you sit quite a bit but I would only worry about this if you were currently trying to conceive and it was taking a little longer than normal.

      If the stickiness is causing discomfort, you could try some sort of talc / baby powder. Typically these are good to prevent moisture and sticking and could make things a bit more comfortable. You could also experiment with different underwear.

      Hope this eases your mind. Let me know if you have other questions.

      Sorry, yes, it is much more likely to be related to reducing the amount of masturbation. Longer periods of abstinence can make it difficult to last a long time during intercourse especially if intercourse is particularly exciting. There are a couple of strategies that you can consider — you could masturbate ahead, you could also try using foreplay to ejaculate early in the process and then penetrate after recovering so that you can last longer. Experimenting with different things should help you find ways to last longer.

      I would recommend getting the boil examined and treated by a doctor. Especially since you have had it for a while and it is getting bigger. You may need antibiotics or other medication to properly treat it.

      Vicks is probably stimulating the area which is causing your penis to get aroused. I think that is normal.
      It shouldn’t cause damage to sperm count, the heat isn’t really temperature heat, it is a heat sensation. Vicks does tend to impact blood flow. There haven’t been any studies that I have seen of people using it on the scrotum…

After applying the ointment, my crotch part felt like burning and really hurt.

      I don’t think so. Some men experience discomfort from frequent ejaculation. If you feel pain other times or the pain is really intense during ejaculation then there could be something going on that you would want to discuss with a doctor.

  83. […] So… what causes this problem in men? Many factors affect the quality of sperm; from internal genetic causes to STIs and even hormonal imbalances. External factors also affect the quality of sperm produced. Environmental factors can greatly reduce the sperm count, chemical exposure in the workplace can be detrimental to sperm health if necessary protection is not ensured (4). The temperature at which testicles are kept is a fine tuned evolutionary process, hence the location of the testes within the scrotal sac outside the body. Changes in the body temperature cause the muscles to bring the testes to (cold conditions) and from (warm conditions) the body to maintain a temperature 4°C below basal body temperature (37°C) in order to prevent morphological changes in the sperm (5).

      I’m sure that really hurt. It shouldn’t cause a problem long term.

    I have chronic prostate inflammation and low sperm mobility (although sperm count is very good). Recently I found out that I also have prostate bacteria infection. I suspect that my low sperm mobility is from the prostate infection or the chronic inflammation. Another possible reason for the low sperm mobility is overheating the testicles somehow.
    The problem with those two possible reasons for my condition is that they require completely different measures: on the one hand to combat prostate inflammation you need to increase the temperature and thus the circulation in the prostate (I have seen there is underwear for heating the prostate for that reason), and on the other hand you need to cool the testicles. Since I am really going to go crazy with this matter: what do you think should I do? Increas the temperature on that area, decrease it or what?

      Have you had antibiotics to treat the infection? If so, how long ago?

    My wife and I are trying to conceive, and I screwed up and went in a hot tub recently. I would say I was in the tub for about 15 minutes at temperature of about 101-103. Do you think this will greatly affect the sperm? Thanks in advance!!

      Those temps can definitely impact sperm but not usually a single offense. I wouldn’t be too worried about it. If it did have any effects, it should sort itself out in about a month or so.

    What is the highest temperature in a pool that would be safe for sperm before it is damaged?

      Ideally 95 degrees or below. Testicle should not reach body temperature or higher

    If you keep your hot tub at a cooler temperature, such as 94 or 95 degrees, will that prevent lower sperm count? I really like the massage that a hot tub gives, but not at the risk of infertility.

      So — couple of things

      1. exposure to heat will not cause permanent damage. So if you have too much heat, your count will go down but it should come back up in a few months (unless you are hot tubbing for hours every days at high temps — then it could take more like a year to recover)

      2. yes, cooler temps would be perfectly fine. wouldn’t cause issue.

      3. if you wanted to make it slightly warmer, you could limit your time or take regular breaks. The hotter the temperature to more frequent you should plan on taking breaks.

      Hope that’s helpful. Happy tubbing.

    Hi Sara

    For the past 15 years, I’ve been directing hot water to my balls whilst in the shower which results in pleasure. Because the water is fairly hot and I expose my balls to hot water for 1 min each time I shower, I am concerned that I may be damaging my prospect of having children. Can you please advise if I should be concerned ?

      I don’t think this should cause long term damage. So I think you are fine.
      If you are actively trying to conceive, it can reduce your chances and you might want to take a break from doing that.
      If you are really concerned, you can get a semen analysis to test your sperm and make sure they are at normal levels.

    Hi Sara I have Cerebral Palsy so i overheat generally anyway, especially when doing sport. My Scrotum is always warm, My wife and i have been trying with no success. IS there something i can do to reduce my overall and scrotum temperature.

      That’s interesting. I didn’t know that cerebral palsy can increase body temperature. You may want to consider snowballs underwear. They specifically have a cooling wedge designed to lower scrotal temp.

      It might if they get too hot. It won’t cause long lasting damage but could temporarily reduce sperm count which could reduce your chances of getting pregnant if you are currently trying.

        A single exposure to high heat is unlikely to cause significant issues with sperm. You may see a temporary dip. If there was any impact at all, it should pass in 6 weeks. But I wouldn’t worry about it.

    Not suffering from any major disease
    Was not on any medication in my entire life

      Have you had hormone tests or genetic tests done? Have you been evaluated by a urologist?

      Heat effects are generally temporary… I wouldn’t expect them to cause a zero sperm count by themselves unless the exposure to hot water was every day for long periods of time.

        I used to bath for 15 minutes in hot water almost boiling and that too directly on my balls
        I have been doing this for last 7 years at least and on a regular basis, as it gives me satisfaction when I pour hot water on them

        I don’t drink alcohol and smoke at all
        Masturbating for last 10 years almost ( can this also effect the productivity)

        Please tell me if there is any hope for the recovery ?
        Could me system start producing them again if I strictly follow a balanced lifestyle and stay away from heat
        Please reply and thanks in advance

        not seen any urologist yet
        My doc suggested me testicular biopsy

          I would recommend to avoid heat and follow a balanced lifestyle. The heat exposure is enough that it could knock your sperm count down. It will take time to recover your sperm maybe 3 or 6 months.

          You may also have another issue, so it would be a good idea to visit a urologist.

Going to get a sperm analysis done after a use the Sauna to see how infertile I can make myself. Been lucky with pull out method so far and we are more careful during ovulation (condoms/abstinence). Thanks for helping me understand how to cook my balls using my Sauna=)

    Hi Sara, I have been a swim teacher for over 25 years. I work about 5-7 months out of the year in heated pools (5 days a week). Daily, I am in the water for 8-9 hours straight. how do you think this has impacted my fertility? Do you think there is a chance that I can still be fertile? It’s never been an issue before now, but It has recently come up in my current relationship.

    Is it ok to have a sauna and steam a few times a week if I cool my balls after? I had a test and the results are a bit dodgy but I’ve stopped drinking. But I do love a sauna…
