Scientists discover reversible male birth control that stops sperm production
(www.sciencedaily.com)
I thought this was being tested a couple of years ago?

Kinda hard to make male contraceptives. Women are naturally infertile for most of the time not spent actively ovulating. They are permanently infertile during pregnancy, real or synthetic. But men? We're always churning out swimmers. When that process stops, something has gone very wrong.
So, artificially induce a naturally occurring phenomenon vs artificially terminate a constant mechanism.
Well not with that attitude!
It is more difficult, but still worth working towards it.
…in mice, after massive, cancer-causing doses, probably.
I'm tired of hearing about this shit. Put it to market or stop talking about it.
Yeah just push it out to public. Just like they did with women's contraceptives.
I have a different solution, its called being a transbian :3
How so? Unless you remove testicles, or your partner is also a trans person, you're still 100% able to have offspring together
I was being more silly than serious :3
Hehe alright!
This kind of news is an annual event at this point.
I just use my personality. Seems simpler.
The new stuff is reversible

That's great but I've been seeing articles like this for decades so I'll believe it when there's an actual working product you can actually get

Easier to target one egg cell than millions of sperm germ cells.
Sure. But the demand is here on both sides, not just one.
Male contraceptives allow men to have reproductive agency beyond condoms and vasectomy, and they can be used in couples where women prefer not to use non-barrier contraception for health reasons or personal reservations.
My situation right here. Condoms suck, vasectomy is too much, and birth control isn't on the table. Please give me a pill already.
Didn't they figure that out with Vasalgel?
If it did, you'd think it would be promoted, like at all. I never hear about it.
Cool. More options for reproductive agency are always welcome.
Last I heard there were some of these contraceptives moving into clinical trials, the ones with gel in the vas deferens,
Anyway it is irrelevant for regular people, because it isn't available and probably won't be within 5 to 10 years if lucky. Maybe it would be relevant if it had a chance of being available in 1 to 2 years , even then who knows how expensive it would be or how long it would take to be accessible, as in a lot of doctors doing it.
Vasagel, based on an Indian product called RISUG
Noone funds it because it's too cheap? No real profit potential?
Essentially -- it's a gel that's injected into the vas def which doesn't actually block the flow totally (which sometimes causes side effects like granuloma in vasectomy), but rather it disrupts sperm cell membranes, but allowing the remains to pass through.
It is reversed simply by flushing it out with saline.
Last time I donated to the project it was at the live rabbit trials stage with Parsemuns Foundation?
(OH WAIT IT HAS BEEN USED IN HUMANS IN THE USA (see wired link below)
RISUG was used in humans for like 20 years with good results I believe.
Really don't understand why this one hasn't gained traction.
