Women are going to college, graduating, and entering the workforce in greater numbers than ever before, and there's good reason to believe that the birth control pill has a lot to do with this. But there's a lot more to the pill than meets the eye. Women go on the pill for a small handful of targeted effects (pregnancy prevention and clearer skin, yay!). But sex hormones can't work that way. They impact the activities of billions of cells in the body at once, many of which are in the brain. There, they play a role in influencing attraction, sexual motivation, stress, hunger, eating patterns, emotion regulation, friendships, aggression, mood, learning, and more. Sometimes these for the better; other times, they're for the worse. More timely than ever, this book helps us understand how the pill works so that we can make the right decisions for our health.
