Magic microchip = super-eco contraception

If you've ever worried about the environmental impact of all those discarded latex condoms, this might be the super-futuristic invention for you! Australian scientists have apparently figured out how to insert a microchip in the vas deferens (that's the part of the male equipment that delivers semen - it's also the tube that gets snipped when a guy gets a vasectomy).

When the man is about to have sex, and doesn't want procreation to result, he can press "pause" on a device that sends RF waves to his intimate microchip. The chip translates the waves into acoustic waves, which then cause the chip to expand, blocking sperm from passing through the vas deferens. When the man wants to switch back to having possibly reproductive sex, no return visit to the doc is necessary - he just presses the reverse function button, and the chip contracts, allowing sperm to pass.

I'm not sure if I quite trust this technology yet, but I sure hope they perfect it soon.
