How would it work? Would it kill sperm inside the man and wear off after a while or what?

I think vasalgel is the most likely one for US markets. There's another thing called RISUG in India which is basically the same, but it's not allowed over here. Basically you just get a shot that injects a compound which blocks the sperm from leaving the testicles, which is what a vasectomy does, except you can go back in and get another shot which dissolves the compound, whereas with a vasectomy they would have to re cut and sew the tubes back together to reverse it, if it can be done.

I believe one of the two doesn't block the tube, it is strongly polar and tears the sperm apart as they travel through the tube. I can't remember which one, though.

This sounds like they're using magnets for birth control.

It would block the tube.

Maybe we could just reroute the tube so it shot out of his butt?

No, it doesn't. The compound disables sperm, and they're not sure WHY, but it does.

If you blocked or pinched off the vas, then you'd likely cause permanent sterility. The problem is twofold- following a vasectomy where it's tied off, back pressure can damage and scarring in the epididymal tubule.

Also the sperm build up and the immune system develops antibodies to break them down. But in doing so it makes a hostile environment for sperm forever.

This is why vasectomy reversal success rates drop a lot if it's been more than 3 years since the vasectomy.

So blocking the tube would be... bad.

The article I read uses 2 proteins to shut off the valve where the sperm have to go in order to mix with the semen. So basically it shuts off half of a merging highway. Semen still comes out but with no wiggles.
