Q: Can the male use a sauna while trying to conceive (TTC)?
A: Heating up the testes may decrease the sperm count. Going into a sauna can heat up the testes and have a negative effect on the sperm even many weeks later. If he wants to improve his sperm quality, he should stay in the sauna only a very short time so that his testes and body won't heat up.
