Prolonged sauna exposure may be detrimental for conception, and using a cold pack on the scrotum may be beneficial.

“Some of this has to do with heat damage to the testes, so potentially cold therapy could be helpful for that.”

“Hot showers are probably fine. But if you're going to go into a sauna, for instance, you might want to rethink that decision. And if you do decide to, you almost certainly would want to bring a cold pack in that you could-- well, hopefully put some material between the cold pack and the scrotum so you don't get a cold burn. But put something there, but keep the scrotal tissue cool.”

“I actually have suggested that that's actually what I do when I go into the sauna”
