To my knowledge this is with 10min connection mid way. This is a big risk to be stuck in the middle waiting for the next train so the big new here is the direct part, making it way more reliable.

It is not in this case at least. The method relies on using a device (usually a ring) to push the testicles hiver in your body, and the temperature there is enough to stop spermatogenesis. The current method involves stopping every 3 years for at l'East 6 months to ensure production returns to normal. There is no documented side effect, though it should be noted that as always in this area, fully documented medical trial are pending. You my ne referring to other methods using higher temps or external device such as heating boxer but i have not experienced not researched those so i cannot answer you.

Yes I'm using it. It works as expected

Yeah my bad for puting both in the same bag i totally agree. I meant to say that thermal contraception is a good alternative to birth control that men can use, just as vasectomy is a viable alternative to tubal litigation. And both are easier and with less side effect than the woman counterpart.

Not saying the pill won't eventually appear but the track record for men contraception hitting the market is not good. It always get cancelled in an endless loop of disapointment.

People serious about sharing the load or protecting women from the aide effect of birth control should look up vasectomy or thermal contraception. It works.

I've been on thermal contraception for 6months myself and my sperm production bas completely stoped with no side effects. Highly recommend.
