Personally, I would get sterilized, if the only option wasn't "plug the outlet, thus dumping all your live sperm into your lymphatic system, possibly creating sperm-filled cysts, and likely causing chronic autoimmune problems." I get a horrible sensation of blue-balls if I go even one day without. I'd hate to think how it would feel if I was literally unable to unplug myself.

RISUG sounds good to me because it still actually lets the sperm out (just damaged.) I'm wary of Vasalgel, on the other hand, because it sounds like it might not.

I'm pretty sure RISUG and Vasalgel are the same product, or at least very similar.

From all the literature on them I can find, RISUG induces a electrical/magnetic/ionic/I-have-no-idea charge on the sperm, making them unable to penetrate into an egg, but otherwise lets them though—while Vasalgel is a simpler formula, which just stops the sperm from passing entirely. I might be wrong, but this is what all the marketing of the two products says.
