Q: My husband goes two to three times a week into our hot tub. Can he do that while we TTC?
A: Heating up the testicles may decrease the sperm count and studies have shown that men whose testes were exposed to heat had decreased sperm counts. Going into a Jacuzzi or hot tub 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, your husband should do anything to prevent the testes from heating up. That may mean staying out of the hot tub or Jacuzzi throughout the time you're trying to get pregnant.
