I stumbled across this possible future form of sperm inhibition today and thought I'd share it with you all. It's called RISUG (Reversible Inhibition of Sperm Under Guidance.) It's an injection into the vas deferens containing polymer styrene maleic anhydride. It seems to be potentially effective for up to 10 years, and is reversible via another injection of dimethyl sulfoxide or sodium bicarbonate. It's far from being approved, and is still in research phases, but I think it poses an awesome answer to a serious problem. It does not protect from STI's, but when in a committed relationship where both partners are tested it could be an awesome tool. I don't know if this breaks the rules or not, but heres a link with some information on it by Bill Gifford, on April 26, 2011.

I understand this thread is about future forms of birth control but tried & true method without possible side effects seems the safest route.

Upside was that we had to try a lot But seriously, the microwaves do end up effecting you long term. Most of the guys I worked with had similar issues, but we were working with much higher energy levels than what the medical community is doing. If you plan on having kids in the future, I would recommend the good old rain coat.

I'm totally game for the idea of male birth control, I've had numerous female partners that have struggled with finding a female option that doesn't wreck havoc on their hormones and mood which makes me think it might be a preferable option.

Either way, microwaving my nuts seems a bit scary lol. And I'd be curious to see long term affects on the body,would there be any mutation or change in the sperm that survive? I concur with the use of a male birth control, I think it'd be something a majority of the american population would use readily. Logically you'd think our reproductive system is easier to manage and interfere with than theirs right? I'd be really interested in reading any other ideas/studies/options people can dig up.
