We all want to be that guy at the gym. You know, the guy with the tree trunk neck dead lifting weights the size of two modest Hyundai sedans. No one would ever accuse that guy of shooting blanks, not just because he looks like he could probably crush you without even setting down his protein shake, but because he looks like the model of testosterone. Testosterone can get you ripped, but it can also hit a guy right where it counts. We sat down with Dr. Werthman to find out exactly what testosterone does to your fertility. Trust us, you might not envy that guy at the gym anymore…
It Rubs The Lotion on Its Skin
So let’s get one thing out of the way: any kind of testosterone, when taken externally, can cause men to stop producing sperm. Testosterone lotions or gels contain chemicals whose side effects can cause azoospermia. They are just as bad for you as testosterone injections. If you have low testosterone and are trying to conceive, there are other medicines that can boost testosterone internally, without hurting your swimmers.
Who messed with the thermostat?
Here’s a bio lesson: your brain makes the hormones FSH and LH, which go in to the bloodstream and are taken up by the testicles. The testes’ job is to produce testosterone and make sperm. The LH causes the release of testosterone. The FSH causes and sustains sperm production. Once the testosterone is produced, a signal is carried to the brain. The brain gets the signal that testosterone is being produced, so it stops making FSH and LH. No FSH and LH means no testosterone or sperm. When the levels of testosterone start falling, the brain clicks on like a thermostat, producing those hormones again and starting the cycle over.
When you take external testosterone, either through a shot or a lotion/gel, you are flooded with testosterone that could last from 24 hours to 3 days. This causes the brain to shut off because your receptors are so saturated, meaning no FSH/LH gets sent to the testicles, so they stop making testosterone and sperm.
If you’re azoospermic (shooting blanks) because of external testosterone supplements, it’s fairly easy to treat. Your doctor will take you off of the testosterone and increase FSH and LH. 90% of men who are azoospermic because of external testosterone will make a full recovery, while 10% will remain sterile.
You aren’t the only one
If you’ve taken external testosterone and are suffering from azoospermia, you aren’t alone. Dr. Werthman has seen an increase in testosterone caused azoospermia. He says this is due to the increased advertising by drug companies, as well as a lack of information on behalf of the doctors who prescribed the testosterone.
What we learned
Juicing is really, really bad for babymaking. Seriously. Don’t do it. Just don’t. Also, long term use of testosterone can cause permanent damage to your testicles. If you are on external testosterone now, talk to your Doctor about natural alternative. Don’t be that guy at the gym.
