The German invented and tested the implant with a switch for sperm

A carpenter from Germany announced a contraceptive revolution . Clemens Bimek believes that his invention will be in demand and popular: he patented and developed valves with switches that are surgically implanted in the vas deferens of men. Closing the valve stops the release of sperm.

A vasectomy , ligation or removal of a fragment of the vas deferens in order to achieve sterility has been carried out for a very long time. The first experiments have been known since the 18th century, and in normal mode, this operation was first carried out in 1899. After the operation, while fully maintaining sexual functions, the ability to conceive disappears in men due to the blocking of sperm output.

In principle, this operation is not considered 100% reversible, and therefore it is recommended for people of a sufficiently large age, or already having children. The laws of some countries formally limit the scope of this operation. For example, in Russia, in connection with the campaign to end the demographic crisis and increase the draft plan in the RF Armed Forces, Russian citizens can only perform vasectomy (and also sterilize women) if they are over 35 years old or if there are 2 or more children, or medical indications.

However, it happens that life circumstances and priorities change over time. Therefore, since 1971, successful operations have been performed that reverse a vasectomy and restore the normal functioning of the reproductive system.



The invention of Bimek, in fact, does not fall under the definition of sterilization, but only gives control over the process of conception. It is possible that in the case of successful tests, the implant will indeed be in demand among the male population.

Bimek said that the idea of ​​such a device came to him 20 years ago, while watching a popular science program. After making sure that no one had registered such a patent, he proceeded to develop the device. “Many doctors did not take my idea seriously. But there were those who inspired me to research and helped with my knowledge, ”he admits.



This year, the first tests of devices on 25 volunteers will already begin. The valve with a switch weighs about 3 grams and is approximately 2 cm long. The implantation operation is performed within half an hour. Access to the switch is through the skin of the scrotum.

Bimek himself has already undergone the implantation procedure - it was carried out under local anesthesia so that he could lead the surgeons. The urologist who assisted during the operation said that in his opinion such an implant is preferable to standard vasectomy. According to him, almost a third of patients after a vasectomy want to return everything back, but this, unfortunately, is not always possible.

Possible problems with valve implantation, according to experts, may be associated with the appearance of scars at the junction with the ducts. In addition, if the valves are left closed for a long time, they may become clogged.

In the case of a successful implementation of the invention, it remains only to integrate the remote control from the smartphone into the switches.
