Sexpert Q&A: Hot Tub Birth Control?
Published January 08, 2015
Hello Dr. Fulbright_ I have heard that heat (such as a hot bath or directly-applied streams of hot water in the shower) can reduce sperm counts (like a natural birth control). How much truth is there to that? DJ
Dear DJ, Exposure to heat impacts a man's semen in primarily two ways: 1. It affects sperm motility. This is in part due to heat exposure damaging sperm as they mature in the epididymis. 2. It affects normal sperm production. (Men with fertility problems are often discouraged from submerging themselves in hot bodies of water).
Heat should not, however, be regarded as a form of birth control. Having sex in a hot environment, like a hot tub, does not prevent pregnancy of sexually transmitted infections.
