Sperm warfare: From from radio-controlled valves to ultrasound male contraception is going high-tech
Times Online ^ | September 20, 2008 | Liz Hollis

Men are short-changed when it comes to birth control. Vasectomy is painful and not always reversible. Condoms blunt pleasure, break and slip off. Or there is that Russian-roulette standby, coitus interruptus.

But science finally may have found an answer for reversible, reliable and easy contraception for men with a new breed of futuristic, nonhormonal gizmos that promise a high-tech solution to sperm control.

Teams around the globe are developing new techniques that can block ducts in the testes, zap sperm before they come out of the body or even scramble sperm production.

“Men want new contraceptive methods,” says Elaine Lissner, director of the 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.”

Professor Derek Abbott and his team from the University of Adelaide 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.

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.

“Vasectomy entails surgery, pain and it might not be reversible. Our micro-valve provides an alternative,” says Abbott. Demand for the new valve has been unprecedented. “I've been inundated with inquiries from men from all over the world,” he says. The device will now need five years of animal trials before it can be used in human beings.

A California team is developing an implantable ring that circles the vas deferens. Doctors can switch it on to zap sperm

I just got an app that turns my iPhone into an air mouse/touchpad. Pretty cool and useful for presentations. I can only dream what’s coming down the pike (no pun intended).

A decade ago demand wasn't there and it was assumed women wouldn't trust men to take charge of birth control anyway.

I honestly do not get this kind of thinking.

With all the whining that men do about how "she got pregnant on purpose" I don't see how the demand could not have been there.

Why would you depend on the other person anyway? You should take responsibility for your own birth control.

I have to say that, as a man who has been single since 2002, I would have loved an additional birth control option for me as a man besides condoms, vasectomy and abstinence.

Yah, right! Sperm cut-off valves only work if you give the body 4-6 weeks to expel all of the sperm that are stored in the seminal vesicles, downstream from the vas deferens where you’ve put the valve. Back to the drawing board, folks.
