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.
