He is concerned that potential scarring may prevent sperm from flowing even if the valve is switched open, and that the valve may become clogged if it is switched closed for too long. The valve is set to be implanted in 25 men during trials starting this year. “My assessment is that implanting the valve could cause scarring where it meets the vas deferens,” Wolfgang Bühmann, spokesman for the Professional Association of German Urologists, said. Under local anesthetic, he was able to guide the surgeon during his own operation, which proved to be successful. According to German magazine Spiegel (via The Telegraph), Bimek filed a patent in 2000, then built the first prototype of the Bimek SLV in 2006. The Bimek SLV website describes the switch as being “as small as a gummy bear. end-of.

The result is similar to a vasectomy, except the patient can allow the sperm to flow at any time whereas vasectomies sometimes cannot be reversed. “Many of the doctors I consulted didn’t take me seriously.Clemens Bimek first came up with the idea of a spermatic duct valve around 20 years ago while watching a documentary about contraception.” When the valve is closed, sperm cells are prevented from being released during ejaculation, leaving the seminal fluid sterile. But there were some who encouraged me to go on tinkering and helped me with their expertise,” he said.COM Published: Jan 12, 2016, 11:19 pm IST Updated: Jan 12, 2016, 11:19 pm IST Carpenter invents a male-birth control that can be turned on and off A still from the pilot episode of Master of None, where the lead couple have a pregnancy scare.During a half-hour operation, tiny valves are implanted in the vas deferens (duct which conveys sperm from the testicle to the urethra) and controlled by a switch that is easily accessed by hand through the scrotum skin.
