This episode explores estrogens and progestins as the pharmacology of cycles and transitions. Rather than single on–off effects, these hormones choreograph phases: growth, differentiation, maintenance, and shedding. We examine receptor subtypes, tissue-selective actions, feedback effects on the hypothalamic–pituitary axis, and the clinical logic behind contraception, hormone replacement therapy, and fertility modulation. The emphasis is on understanding context: the same hormone can protect, provoke, or harm depending on timing, dose, and tissue.
Key takeaways to hold the thread:
Cyclic logic: why sequence matters more than concentration alone.
Receptor diversity: ERα, ERβ, and progesterone receptors as context-shapers.
Central vs peripheral effects: feedback, suppression, and escape.
Therapeutic intent: contraception, replacement, induction, and suppression.
Risk–benefit framing: thrombosis, cancer risk, and cardiovascular nuance.
