The future of contraception may allow men to control their fertility with just a flip of an on-off switch! This switch, called the Bimek SLV, was developed by German researchers. This might just be the most innovative uses of technology when it comes to birth control for men.
How exactly does it work?
It’s a small device about the size of a gummy bear that attaches to each of the two spermatic ducts and functions to regulate the release of sperm cells. In its closed state, the device obstructs the release of sperm during ejaculation. It diverts only the flow of the sperm cells, not the ejaculatory fluid. So men can expect to ejaculate normally. Sperm actually makes up only about 5% of the ejaculatory fluid. The rest is made of other substances such as proteins, enzymes, and water.
Conversely, the valve can be easily switched open and allow the release of sperm, immediately restoring fertility. The sperm cells that are blocked are ejected out of the spermatic duct through several outlets on the device. Outside of the ducts, special cells known as phagocytes break down sperm. The Bimek SLV is proposed as a life-long, hormone-free method for men to control their fertility.
What would the experience of getting this entail?
First off, a medical examination would be required to make sure that he is a good candidate for the device. An incision is made on the testicles and the devices inserted. The procedure to implant the switch is similar to undergoing a vasectomy. Therefore, the risk of complications or adverse effects after insertion is very low. The procedure itself takes only 30 minutes and is done under local anesthesia. And although it only takes only 1 day to recover, it does take 3 to 6 months before the device becomes completely functional and is able to divert sperm from the ejaculatory fluid.
How much does it cost?
Estimated costs for the surgery and the two Bimek SLV valves is about €5000 Euros or about $5,400 US dollars. Pricey, indeed!
It may be years before this device even lands in the US marketplace because it still needs to undergo clinical trials to make sure it’s safe and effective. If everything runs according to schedule, the device is projected to receive European market approval in 2018.
