Aside from vasectomies, few viable male contraceptive options exist. The latest entrant into the market, called the Bimek SLV, is a proposed “sperm switch” created by German inventor Clemens Bimek. The small device works by attaching to the spermatic duct valve and can be switched to the “off” position to divert the flow of sperm back into the testicles upon ejaculation. According to Bimek, the device could then be turned back on at any point, making it a temporary contraceptive unlike vasectomies, which are sometimes irreversible.
