Did you know that a woman can only get pregnant a few days each month — and that her body gives her clear signs of when those days are?

In this episode of The Bioethics Babe Podcast, Dr. Marguerite Duane, board-certified family physician and co-founder of FACTS About Fertility, reveals the science behind fertility awareness and restorative reproductive medicine.

Dr. Duane shares how a night hospital shift changed her entire understanding of women’s health, why fertility awareness is not the old ‘rhythm or calendar method,’ and how tracking a woman's natural biomarkers — like cervical fluid, basal body temperature, and hormone levels — can help women and couples understand their fertility, address root causes of reproductive health issues, and move beyond the era of unhealthy hormonal contraception. Dr. Duane has become a national leader in fertility awareness education.

Whether a woman is trying to conceive, manage her health naturally, or simply wants to understand her body better, this conversation will change how you think about women’s health and couples’ fertility.

We discuss:

  • How Dr. Duane discovered fertility awareness during residency
  • The truth about fertility awareness-based methods (FABMs) vs. the rhythm method
  • How cervical fluid, hormones, and temperature reveal fertility
  • The medical science behind FABMs
  • What apps and tools actually work — and which ones to avoid
  • The mission of FACTS and how it’s transforming medical education
  • Why fertility awareness is for every woman and for couples
