Vasectomy or simply male sterilization could soon by a new Invention thing of the past. The German carpenter and inventor Clemens Bimek allows men, A simple flip of „sperm switch“ their fertility to the inside of the scrotum control. Some urologists are skeptical, others speak of a medical revolution.
The story of Clemens Bimek is a, when you are amazed and surprised at the same time. It is also a story, which the listener wrests respect for Bimeks perseverance and his will. Because he believes in his idea. She began watching television, sometime in the late 90s in the suburbs of Berlin. After a hard day on the construction Bimek sitting exhausted in front of the television and watched a documentary about prevention. It was just not so good at his job. The jobs were scarce. And in his trained profession as a cabinetmaker master it looked worse. In the documentary was the Anatomy declared the man: As the sperm are produced in the testicles, flow through the epididymis and vas deferens, the two direction urethra and mix with the ejaculate. And as in the so-called vasectomy, sterilization, the vas deferens are severed. A surgery, which often ends the fertility irretrievably.
Bimeks first thought, when he saw the diagram: Why not just build one valve in both vas deferens a? The idea revolved henceforth in his head. He probably would have done so long, until he would eventually disappeared, if Bimek would not be passed on his way to work every day at the Berlin Patent Office in Kreuzberg. Always when he passed there, he thought of the valve. And it, that certainly must have had someone the same idea before him. Eventually he stopped finally and asked for. A patent for a vas deferens valve does not exist, told him the officials with. „How it all began“, says Bimek.
So he began to tinker and to circulate literature, briefed at medical technology companies about possible materials for a valve. In order to plan the diameter of the valve ports, He even asked for pathologists to, if he could not have the seed head of a dead – without success. Also from the urology world there was plenty of head shaking for the enterprising carpenter. „Many doctors, I asked for advice, did not take me seriously. But there were also some, who encouraged me, to continue tinkering and who have supported me with knowledge“, says Bimek. The longer he was investigating and reading, the less reasons he found, who spoke against his idea. Finally, he actually filed a patent. Year 2000 was the „Shutter to contraception for use in man“ approved. 2006 he built the first prototype. The Bimek SLV is in a half-hour operation – similar to a vasectomy – can be used in both vas deferens. When closed, it prevents the flow of sperm – the man is sterile, but can ejaculate normally during sex with a woman. If he wants to have a child, he puts a switch on the valves, he can grope under the skin in his scrotum. Now he is immediately procreative. Bimek protests, that it should come to the valve support to no complaints. Neither was the libido restricted nor get it otherwise any adverse health outcomes. For this purpose, neither the two-gram valve the size of a jelly baby still, the switch should be felt.
Arguments for the benefit of its development, there are enough: Prevention is no longer just women's business – about half of all adults sat in the prevention on the pill. A corresponding product, for the man has not been brought to market. Moreover, would have to Women no longer deal with the hormonal stress on the pill, the many poorly tolerated. That did also good for the environment. Because so far are hormonal residues, which enter via the urine in the water cycle, not filtered out of wastewater treatment plants. This leads to strong water pollution. The cost of the pill, Condoms or other contraceptives would pay for itself in a valve sometime. The Bimek SLV to last a lifetime – is according to current state with an estimated retail price of 3000 Euro but not low. The cost in mass production are likely to be lower but significantly.
