Science hasn't really gotten birth control down pat. After my wife got pregnant while on some chewable (I'm not kidding) baby regulating pills, you can say I kind of lost my faith in the system. It's not like that was the only options we tried or considered. The IUD was uncomfortable (for both of us, it was like a tiny copper wire would randomly assault my pee-hole whenever we had sexy times), and her previous contraceptives made her feel all bloat-ey and un-pretty, not something she was really into. She wasn't really crazy about my gung-ho-ness about getting a vasectomy because children. And condoms just defeat the purpose of getting married in the first place. So my wife and I would sit around, dreaming of a day when I'd be able to just turn my fertility on and off.

And it looks like Science is doing just that.

Clemens Bimek is a German inventor who's developing a "sperm switch" which will allow men the ability to stop/start their semen flow.

Sperm Switch

It's about the size of a gummy bear (not the best of comparisons).


The switch is inserted into a man's scrotum with a 30-minute procedure. Here's the normal flow of sperm from testes to tip.

This is what happens when the switch is off.


So you flick the switch through the skin of your ball-sack.

Sperm stopping powers, activate!


And watch the sperm cells stop dead in their tracks.

Take that child support!


You'll still have ejaculatory fluids, they just won't be riddled with all of the pesky, baby-making cells in your sperm.

“After the valve is closed there will still be sperm cells present in your ejaculatory fluids for up to 3 months or about another 30 ejaculations. To be completely sure of sterility it is essential that you undergo a sperm analysis, or spermiogram, with a urologist. This is the only way to be 100% sure.”


So it takes about 3-6 months until your semen is devoid of any sperm cells entirely, but once you flick that switch back on, you're virile again.

It's good to see that more and more male contraceptive options are becoming available that don't include potentially irreversible surgical procedures. Now it'd be great if it vibrated just a little, so you know it's on or off, but then again if it shakes while it rubs up against the testes...that'd be pretty painful.
