Put a Switch on Your Junk to Shut Off Sperm Flow

Every year, a better mouse trap is thought of to make tomorrow even better. Implanting a switch is the new idea. But, before we look at it, let’s see some other alternative methods that aren’t well known.

Boys Will Stay Boys

Gamendazole is used to help cancer patients. Little did they know their patients (men anyway) also would develop low sperm counts. It accomplishes this feat by inhibiting the sperms ability to mature into viable little baby makers. Currently in the monkey research stage. Who would have thought sperm could actually become mature?

Bullish on heat

Ultrasound may be an option. It has been long known that raising the temperature of the testes can reduce sperm count. Over a hundred years ago, farmers with a small herd had this as an option. They would do this by literally ‘kicking’ the bull in the testes knocking it up into his body where body warmth turned him into a steer. Later, when the testes would eventually drop out again, the procedure would be repeated. The ranch-hand would have drawn an extremely short straw to get stuck with this job.

Ultrasound has been found to be ten times more effective. One of the drawbacks is it can be permanent. Results are yet to be consistent.


This one still needs some work. Like Gamenzadole, it causes sperm to be released before they are ready or still immature. It is the method in which you have to take the medicine that brings the problem. It has to be given through injections and only lasts a short amount of time. “Are you ready, Honey? Just a second. I need to give you a shot.” Mood killer extraordinaire.


There are two products getting ready for market. One is called Vasalgel and is being developed here in the United States. The other is Risug and has been developing in India for decades. They are both similar to each other with a small difference.

Both will inject a polymer gel into the man’s Vas Deferens to block travel by sperm. Where Risug is claimed to electrically shred a man’s sperm, Vasalgel will simply block it. Both methods were created as an easily more reversible way for contraception than a vasectomy. Both are close to the clinical trial stage.

Whether you want to zap your sperm or just hold it up for (years) later, the ol’ firehose will still work in the meantime.

Clap on.  Clap off.

And finally, the newest method that brought us all here. The switch, or valve is actually inserted inside the man’s body on the Vas Deferens in the same location that a vasectomy is performed. Only, instead of cutting the supply tube, a valve is placed on the tube that can be turned on and off. Having a hot date tonight? Turn it on. Staying home and watching the game? Turn it off.

Later this year, 25 men have volunteered to have the device implanted for a trial study.

What surprises me the most is who came up with the prototype. It wasn’t a doctor. It was a carpenter. I can see a plumber thinking of this but wouldn’t a carpenter have come up with something that could perform the job in a more nailed-shut way?


Which of these would you be willing to try if proven safe?
