progesterone One of the progestogens, steroid
sex hormones, which are synthesized in the initial steps in the biosynthetic pathway in the gonads that converts cholesterol to androgens and to oestrogens; or any natural or synthetic steroid having a progesterone-like action. Progesterone is the main progestogen produced by the ovaries, particularly in the second half of the
menstrual cycle after ovulation has occurred and the empty follicle has formed a
corpus luteum. They are also important hormones in
pregnancy and secreted in increasing concentrations during gestation.
