German Carpenter's Testicluar Valve Could Mean An On/Off Switch For Sperm

Posted by timothy on Thursday January 7, 2016 @07:04AM from the this-one-goes-to-zero dept.

Press2ToContinue writes: A German carpenter has invented a valve which he claims will revolutionize contraception, by allowing a man to turn the flow of sperm from his testicles on and off at the flick of a switch. It (the switch, of course) is nearly an inch long and weighs less than a tenth of an ounce. It is surgically implanted on the vas deferens, the tube that carries sperm from the testicles, in a half-hour operation, and controlled by a switch beneath the skin of the scrotum.

So far Bimek is the only man who has the switches implanted, one for each testicle. I wonder what other switches we will see implanted into humans in the future? I think I'd like a valve for adrenaline control.

Recall my doctor telling me there would be residual viable sperm around for sometime after I was snipped. Pretty sure you can't just go flippedy flip on the switchety switch and not make a baby with your baby.

I got a vasectomy a few years ago and I was told that there were about 20 'loads' in storage past the vas deferens. So this is not something you can switch on Friday afternoon and expect to be sterile over the weekend.
