New Human Sex Hormone Could Lead to Male Birth Control Pill

Some men already have their own form of birth control: a lame personality. But as National Geographic reports, the discovery of a new human sex hormone, Gonadotropin-inhibitory hormone (GnIH), could lead researchers to develop the first male birth control pill. GnIH suppresses the release of a series of hormones that prime the body for sex and reproduction (TMI, right?).

Researchers suggest this new wonder hormone could slow down the male reproductive system naturally and without side effects. Heaven forbid a male birth control pill that causes weight gain, breast tenderness and becoming inexplicably emotional. But don't resent this double standard just yet... according to the chief of the U.S. National Institute of Health's Reproductive Sciences Branch, Louis DePaolo, "It's too premature" (that's what she said!) to consider a male birth control pill. Researchers still need to learn much more about GnIH, such as exactly how it works in humans and together with other hormones.

So it seems one day there could be a male birth control pill, but there will never be a science to finding a guy with whom you actually want to procreate.
