Heat application to testes and cool down
According to research I’ve read, application of heat to the testes leads to death of sperm, loss of testosterone and a whole bunch of other problems. Is there any concrete evidence behind this? And if so, anyway to combat it when heating the penis?
Also, as I’m creating a “modified” version of the newbie routine (double the length of warm up time with IV lamp & repeated at the end) would creating a “cool down” routine be beneficial? I’m thinking after my final warm down after the session, I apply a cold rice wrap to my penis, then massage with ice. Any feedback would be greatly appreciated.
