Abstract
Hilgers distinguishes isomolecular hormones -- molecules structurally identical to endogenous estradiol and progesterone -- from heteromolecular artimones, his term for synthetic analogues such as medroxyprogesterone acetate, norethindrone, and ethinyl estradiol, which differ in receptor binding, metabolic pathways, and systemic effects. NaProTECHNOLOGY restricts hormone therapy to isomolecular compounds administered in cycle-synchronized, physiologic doses because artimones suppress the hypothalamic-pituitary-ovarian axis, mask underlying pathology, and produce non-physiologic metabolite profiles incompatible with a restorative reproductive medicine approach.
