How Birth Control Pills Change Which Men Women Are Attracted To

Women’s behavior changes in several ways when they reach the most fertile part of their menstrual cycle--that is, when they ovulate. Among other things, research has found that ovulating women fantasize about sex more often and are more likely to wear red or pink clothing. Interestingly, ovulation also appears to change which kinds of men heterosexual women find most sexually attractive, such that they tend to be drawn to “manlier” men during peak fertility.

So what happens when women take birth control pills or other hormonal contraceptives that prevent ovulation? The end result is that they don’t experience these same cyclical shifts in their patterns of sexual attraction and behavior.

Given that they influence the kinds of men that women find attractive, what implications do birth control pills have for women’s relationships? That's the subject of my latest column over at Playboy. Research suggests that being on the pill might not only influence who heterosexual women choose as partners, but how satisfied they are with their relationships in the long run.
