Hot tubs. Are they really a problem??

[EmberR]

My husband has had a sperm analysis and has good motility and count (he did a home test so don’t know morphology but I will get him to test in a clinic).

he really wants to buy a hot tub - I read all about hot water being bad for fertility. Does anyone think this is really true? If we use it once a week? I don’t want to make him stop doing anything fun whilst TTC. I’ve already pushed on alcohol, coffee etc…

So I looked into hot water as my partner has baths for psoriasis. The information I found out was even just 2-3 times a month was enough for them to see a drop in quality in three months time. The heat fragments the DNA meaning more chance of a chemical pregnancy etc.
The study removed the hot baths and saw such an improvement again at three months that they said you could effectively use heat as a contraception! I was so shocked. Lower quality was also recorded from people using laptops on their laps.

They really don’t like heat, and I thought it would be fine as we’d just avoid the fertile week, but I hadn’t realised sperm mature for 90 days inside the body before release, and during that time they’re exposed to diet and lifestyle.
