Understand Female Desire, Attraction, and Partner Choice | Sarah Hill EP 227
In a Nutshell
Hormonal birth control dampens women's natural estrogen-driven preferences for masculine, genetically compatible male faces and scents, leading 20-30% of women to lose attraction to partners chosen while on the pill after discontinuing, potentially contributing to relationship dissatisfaction, infertility, and suboptimal offspring health. Naturally cycling women experience two hormonal phases: high estrogen in the follicular phase boosts sexual desire, energy, and partner discrimination for conception, while luteal-phase progesterone prioritizes pregnancy optimization, raising metabolism (needing 140-200 extra calories), threat sensitivity, and pair-bonding over raw lust. Sarah Hill's *The Period Brain* empowers women to embrace cyclical brain shifts for better health, mood, relationships, and identity—effects often misattributed to flaws until years post-pill, as receptors resensitize and false self-narratives rewrite.

When women use hormonal birth control, they create a more feminized male face in digital programs testing ideal male faces, compared to naturally cycling women. Women have been led to believe the only way to promote an egalitarian society is to deny biological differences with men 100%. Most insights on heart attacks, good nutrition, and sleep requirements are based on research conducted in men. Beginning to understand what your brain and body are doing as you move between different cycle phases—what 50% of the population is female. Even men trying to avoid women will interact with them.
Sarah Hill, welcome back. This is exciting. New book, The Period Brain.
Dr. Sarah Hill is an evolutionary psychologist, researcher, and professor. She studies women's brains and psychology, specializing in women's hormones and hormonal changes influencing how women think, feel, and experience the world. Focuses on naturally occurring hormones and impact of hormonal birth control on women's psychology.
She taught a course at Peterson Academy on evolutionary approaches to human behavior, sex differentiation, biological differences between men and women, men's and women's hormones, and effects of hormonal birth control, which flatlines hormones and replaces them with synthetics. Covers evolutionary approaches, sex differentiation, neuroendocrinology, and the pill.
After previous podcast, information on birth control effects should be known by everyone, including men dating women. A clip on mate selection and birth control went viral on TikTok.
