Progestogens

Progesterone (P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. Progesterone receptor. (1a28). Water molecules are shown as red spheres. Progesterone is a negative allosteric modulator of nicotinic acetylcholine receptors, and a potent antagonist of the mineralocorticoid receptor. Hydroxysteroid dehydrogenase, 20-α HSD is involved in the control of progesterone level in pregnancy of mice. 17-β HSD is involved in the conversion of androstenedione to testosterone.
