The first females to take the birth-control pill - way back in 1960 - were amazed by its life-changing strength (yay, reproductive freedom!). But today's women don't give the ultra-common contraceptive much thought. They should: Turns out, the Pill can affect everything from your bones to your brain to, yes, your sex appeal.

The Pill works by tricking your body (via artificial versions of the female hormones estrogen and progesterone) into thinking it has already ovulated. In other words, your ovaries don't release a monthly egg (sorry, eager-beaver sperm). The process sounds deceptively simple, and it works. But the steady levels of excess hormones floating through your bloodstream are doing much more than pushing the pause button on reproduction.
