ENDO/REPRO WEEK 2: Hormones, Pregnancy, Labor, and Lactation

This video provides a high-yield, mechanism-driven overview of reproductive physiology, focusing on how hormonal signaling, embryologic development, and neuroendocrine feedback integrate to control gametogenesis, pregnancy, labor, and lactation. Rather than memorizing isolated structures or hormone lists, this review emphasizes physiologic logic: how genetic sex determines gonadal development, how hormones guide reproductive differentiation, how the hypothalamic–pituitary–gonadal axis regulates reproductive cycles, and how coordinated endocrine signals allow fertilization, pregnancy maintenance, childbirth, and breastfeeding. Topics covered (in order) include: • Pelvic anatomy and reproductive compartments • Autonomic pathways to pelvic organs and reproductive function • Gametogenesis and the biology of fertilization • Genetic sex determination and the role of the SRY gene • Development of testes and ovaries from the indifferent gonad • Anti-Müllerian hormone and testosterone in male differentiation • Dihydrotestosterone (DHT) and development of male external genitalia • The default female developmental pathway in the absence of testicular hormones • Enzymatic regulation of sex hormones, including aromatase and 5-alpha reductase • Hypothalamic–pituitary–gonadal axis regulation of reproductive hormones • The ovarian cycle: follicular phase, ovulation, and luteal phase • Corpus luteum function and progesterone-mediated endometrial preparation • Early pregnancy hormone support and the luteal–placental shift • Placental endocrine function and hormone production during pregnancy • Hormonal changes near term and the functional withdrawal of progesterone • Estrogen-mediated increases in uterine contractility before labor • Prostaglandins and their role in uterine contractions and cervical ripening • Oxytocin physiology and its role in coordinating labor contractions • The Ferguson reflex and the positive feedback loop driving childbirth • Lactation physiology: prolactin and oxytocin regulation of milk production and ejection • Lactational amenorrhea and prolactin-mediated suppression of GnRH • Lymph drainage of the pelvis This video is intended as a supplemental conceptual review, not a replacement for lectures, labs, or assigned course materials.
