I am a health hacker and engineer who is using Trak to keep tabs on my sperm concentration. Here are my thoughts and impressions of the product.
Can heat be used to lower sperm count? Sperm are much more sensitive to heat than the rest of the body. Prolonged exposure to heat sources such as hot tubs is a well-known cause of reduced sperm count. Repeated and consistent exposure to heat can knock down sperm count so low that it can render a man temporarily infertile.
