Overview of Reproductive Hormone Pharmacology: Estrogens, Progestins, and Androgens

Reproductive pharmacology organizes gonadal hormone drugs into three parallel axes—estrogens, progestins, and androgens—each paired with corresponding antagonist classes, where agonists and antagonists at times produce overlapping downstream effects rather than strictly opposite ones. Within each axis, agents are further subdivided by mechanism, such as receptor antagonists (full or selective), aromatase inhibitors, synthesis inhibitors, 5-alpha-reductase inhibitors, and GnRH agonists/antagonists. This is a topic within endocrine/reproductive pharmacology, focused on the mechanistic classification of hormone-modulating drug classes rather than specific agents.
