Added 2021-08-27 17:15:32 +0000 UTCAs a man on a constant quest to optimize my brain and body (including my own balls), I decided to actually look into the health effects of UV light on the genitals. To my surprise, some studies have actually demonstrated that exposing the torso or the testes to light can potentially increase testosterone. In fact, studies on the effects of light on the testes go way back to 1939, when researchers exposed various parts of men's bodies to UV light. They found that men’s testosterone levels went up by 120% when the participants’ chests were exposed to UV light, and they went up by 200% with UV exposure to the genital area. (This was the same study former professional baseball player Gabe Kapler cited back in 2015, when he advocated for tanning your testicles in a blog post that later went viral.)
