The science of menstruation in 10 minutes | Dr. Jen Gunter


Listen Later

đŸ©ž **“No, Periods Aren’t for Detox – And Humans Don’t ‘Cycle Sync.’”**

Renowned OBGYN Dr. Jen Gunter busts some of the most harmful myths about menstruation, from the fantasy of pheromones and "cycle syncing" to the false idea that periods cleanse the body of toxins. Menstruation isn’t a monthly detox—it’s a complex biological process deeply tied to human evolution, reproduction, and health.

She warns: most people, including many doctors, are dangerously underinformed about what a normal cycle looks like. And that ignorance isn’t just annoying—it’s being weaponized by laws that treat women as little more than vessels for pregnancy.

Dr. Gunter explains the real science behind menstrual cramps, PMS, and the role of prostaglandins—the real culprits behind period pain and menstrual diarrhea. Apps and social media may glamorize menstrual tracking or fitness syncing, but she emphasizes: much of that advice is based on bad or no science—and in some cases, tracking apps could be used against women in places where reproductive rights are under attack.

đŸ”„ "Evolution doesn’t care if you suffer,” she says. “It just wants you to reproduce." That’s why **understanding your cycle is not just about health—it's about power**.
