What if the birth control you’re taking every day is quietly changing your brain, your mood, your relationships—and even who you’re attracted to? In this groundbreaking episode of hol+, Dr. Taz MD sits down with award-winning researcher and author Dr. Sarah Hill (This Is Your Brain on Birth Control) to reveal the shocking, little-known science of how hormonal contraception shapes not just your reproductive system, but your entire mind and body.

From altered stress responses to shifts in attraction, depression risk in teens, and the controversial “bikini science” problem in medical research, Dr. Hill pulls back the curtain on decades of overlooked studies that every woman and parent should know about. She shares her own journey from evolutionary psychologist to outspoken women’s health advocate, explaining why synthetic progestins are not the same as progesterone, how birth control affects your immune system, and why teenagers may be especially vulnerable to its mental health effects.

If you’re a woman in your teens, 20s, 30s, or 40s—or a parent guiding your daughter—this episode could change the way you think about hormone health, fertility, and your body’s natural rhythms.

Dr. Hill and Dr. Taz discuss:

• How birth control changes the brain’s structure and function
• The difference between progesterone and synthetic progestins (and why it matters)
• Why “bikini science” has failed women in medical research
• The surprising link between birth control and partner attraction
• The immune system’s hidden connection to hormonal cycling
• Teen mental health risks: depression, anxiety, and brain development
• Safer contraceptive choices and how to support your body if you use the pill
• How nutrition and micronized progesterone might help offset side effects

This conversation is more than just information — it’s a wake-up call for how we study, prescribe, and support women’s health.

Topics Covered:

• Hormonal birth control’s impact on the brain
• Synthetic hormones vs. bioidentical hormones
• Partner choice and relationship satisfaction research
• Autoimmunity and immune system differences in women
