German carpenter surprises with "contraceptive valve" invention

A German carpenter has invented a new family planning method for men, using a tool that can regulate semen volume.

According to German magazine Spiegel, Clemens Bimek said he has found a way to attach a wooden valve to the male scrotum, allowing him to control the flow of semen.

​

“I consulted many doctors, and most of them did not take me seriously. But there were still some who encouraged me to pursue this idea and helped me.”

​

To date, Bimek is the only person to have had this special valve implanted in a human. The device, which he invented, is less than an inch long, weighs less than a tenth of an ounce, and is placed in Bimek's vas deferens.

​

Hartwig Bauer, the urologist who performed the valve surgery on Bimek, said the implantation of the valve was a better option than a vasectomy. However, Wolgang Buhmann, representative of the German Association of Urologists, disagreed.

“In my opinion, the placement of this valve would cause scarring of the vas deferens,” he said. The scarring would block the flow of semen even when the valve is open, and the valve could become blocked if left in place.

​

Anneke Loos, director of the Center for Testing Medical Products in Hannover, said the Bimek valve could be used for transplants in other parts of the body. The only remaining question is whether the valve will cause problems when implanted.

This special valve will be implanted in 25 men participating in the trial, starting earlier this year./
