Can cold packs protect the scrotum?

Using cold packs can be helpful in protecting the scrotum during exposure to high temperatures, such as those in saunas or hot baths. Cold packs can help keep the scrotum cool, which is beneficial for maintaining sperm quality and overall testicular function. The scrotum and testes are designed to operate best at temperatures slightly cooler than the body's core temperature. Excessive heat can negatively impact sperm production and hormone levels.

Andrew Huberman notes that using a cold pack inside the sauna helps mitigate the detrimental effects of heat on the testicles, which can otherwise reduce sperm count and affect fertility 1. He also advises that while it's important to keep the scrotum cool, there should be a layer between the cold pack and the skin to prevent any risk of frostbite or skin damage 1. Ultimately, maintaining a slightly lower temperature for the testes is crucial for spermatogenesis and overall sperm health 2.
