Key Takeaways

  • Attraction myths debunked: Studies claiming the pill changes mate preference failed to verify ovulation timing. Newer research with 6,500 participants using hormone verification found no difference in facial preference between pill users and non-users, contradicting evolutionary psychology theories about masculine versus feminine face attraction.
  • Mental health risks confirmed: Clinical trials show four to ten percent of pill users develop depression symptoms. The pill reduces sexual desire, arousal, and pleasure by approximately seven to eight percent on average. Mechanisms involve hormone receptors interacting with neurotransmitters like serotonin, not brain structural changes.
  • Actual medical risks quantified: Blood clot risk increases from three per ten thousand to six per ten thousand. Breast cancer risk rises from five to six per ten thousand to seven per ten thousand. The pill reduces endometrial and ovarian cancer risk, contradicting claims about widespread dangerous side effects.
  • Fertility awareness effectiveness: When tracking cervical mucus texture, basal body temperature, and ovulation test strips perfectly, fertility awareness methods achieve 99.6 percent effectiveness matching the pill. However, method requires daily monitoring and fails with stress, fever, or infections affecting body signals, making consistency challenging.

Notable Moment

A study analyzing armpit odor throughout menstrual cycles using chemical pumps found no distinct ovulation scent. Men could not identify fertile window samples by smell, disproving theories that hormonal birth control masks natural fertility signals that attract partners.

Hi. I'm Wendy Zuckerman, and you're listening to Science Versus. This is the show that pits facts against fallopian tubes. Today, we are tackling the pill. The pill burst onto the scene in the nineteen sixties. And for tons of folks, it was seen as this wonderful thing. Country singer Loretta Lynn even wrote a song about how the pill was gonna open up all of these possibilities for women. But all I've seen of this old world is a bed and a doctor bill. I'm tearing down your frugal ass because now I've got the pill.
