An Australian group of scientists led by Professor Derek Abbott from the University of Adelaid have invented the first remote-controlled key fob that allows men to control a valve that can switch their sperm flow on and off as required.
“Men want new contraceptive methods,” says Elaine Lissner, director of the non-profit Male Contraception Information Project in San Francisco. “A decade ago demand wasn’t there and it was assumed women wouldn’t trust men to take charge of birth control anyway. That has changed.”
The size of half a rice grain, the “fertility control micro-valve” is injected by a doctor into the vas deferens, the duct that carries sperm from the testes, a process that needs only a local anaesthetic. The valve can then open and close to control sperm flow out of the body.
Demand for the new valve has been unprecedented. “I’ve been inundated with inquiries from men from all over the world,” Professor Abbott says. The device will now need five years of animal trials before it can be used in human beings.
In five years, we might not be interested in the contraceptive, but there will be a whole new breed of men that will want to avoid getting a girl knocked up by any means necessary.
