It's no secret that women have it harder than men. But they don't mind. It allows them to complain more. Still, they'd probably like it if the world took some burden off of their dainty backs and handed it to the men in their lives.

That's just what some scientists in China are trying by developing male birth control. A study in which men were injected with testosterone undecanoate in tea-seed oil was recently completed and the results were promising: only a 1.1 percent failure rate, equal to the female pill.

Sounds great for women, right? But would getting shot up full of pregnancy-fighting hormones be cool with you?
