text: Don't worry about it.  You might kill off sperm in your system during the spa time, but those balls are hardier than you think.  Sperm produced outside of the hot tub should be fine. \nI used a very hot hot tub every day for years at the Y--usually 110-112; also have 3 kids from that same time period.  If you do have very low sperm count, or the sperm fertility is very low, you might want to forgo hot tubs completely if you are trying to reproduce. \nIf you are not trying to reproduce, then enjoy the hot tub. We have too many experts out there telling us how we need to be living,  and we forget to just enjoy life.
