>> a non-significantly higher rate of abnormal sperm concentration was found (47.1% versus 11.1%). As someone contemplating a vasectomy, that's not quite the result I was hoping for. Sure would be easier to just keep my phone in my front pocket. Though, I suppose I'm not really sure what "abnormal" sperm end up doing. It's kind of implied that means they just don't work when the abstract starts out "Male infertility constitutes 30–40% of all infertility cases." but what if those sperm cause birth defects instead? Seems like that's a far from ideal result as well. As always... "Investigation using large-scale studies is thus needed."

Maybe somebody could create an app for that, somehow optimize the radiation for killing sperms...

  There is research on ultrasound devices which do what you're asking. Designed to work as short-medium term contraceptives[0]. That isn't how smartphones kill sperm however, just as an aside for getting the same-ish results.

    Thanks for that link. Interesting. There's also the evidence... which needs more corroboration to be sure... that heat above a certain temperature kills them or weakens them. Small scale experiments and survey of blast-furnace workers provided evidence for it. With both, the fertility went back to normal I think a few months after they left the environment where they were overheated. So, initial evidence for sperm-killing heat to be a safe and effective contraceptive. Doesn't feel as bad as you'd think, either.

Perhaps you can boost radiation levels by leaving your phone on a call with a white noise generator and tuck the phone in the front of your [under]pants.
