But reducing the total amount of time that you spend seated is really important if you want to keep the temperature milieu of the scrotum optimal for sperm quality and fertilization.
The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Really the principle is what's most important, which is to keep the temperature of the scrotum and testicles lower than the rest of your body.
I think the spermatogenesis or sperm production is certainly a lot more sensitive you know whether you can sort of thwart the effects of external heat with a cooling pack I think it makes sense there are studies that have looked at different ways to cool the scrotum and have compared you know semen quality before and after and there's some data that may help
