The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

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.

Look, it's very clear that avoiding being too close to the phone is probably better for your sperm quality than putting the phone very close to your testicles or anywhere else on your body.
I would suggest yes, if you are somebody who is seeking to conceive. I'm not somebody who is going to stop using my smartphone. I don't expect anyone's going to stop using their smartphone. The question is, should you carry it in your front pocket if you're a male? I think, to be on the safe side, the answer is probably avoid doing that too much of the time.
But the temperature effects of the phone, it turns out, are enough, even under conditions in which people don't report it to be uncomfortably warm, that it can change the temperature milieu of the testicle in ways that can diminish sperm quality.
Why? Well, because you might have heard that carrying your phone in your pocket can reduce your testosterone levels and sperm count. And guess what, that is true.
The discussion I'm about to have with you relates to the fact that the electromagnetic fields and the heat-related effects of smartphones can indeed have a detrimental effect on sperm quality and, yes, indeed, on testosterone levels as well.

I believe there are studies showing that if you put your cell phone in your pants it can reduce sperm counts and potentially testosterone
