There was this gel that got injected into the tube connecting the balls to the urethra(vas deferens?). It would destroy the sperms as it went through and you where basically sterile. To reverse they injected you again with something and it would become a liquid and you ended up busting it out in a few ejaculations. It's been stuck in early human trials for a decade.

Jesus, I read about that technique in a science magazine in the 90s.
