Pharmacological action

Medroxyprogesterone acetate is a synthetic progestogen, which has a longer duration of action than natural progesterone. Medroxyprogesterone acetate affects the hypothalamic-pituitary system, blocking the secretion of adenohypophysis gonadotropic hormones (FSH and LH). Reducing the level of gonadotropic hormones in the blood leads to a violation of folliculogenesis in females, resulting in inhibited follicular ovulation and no fertilization.
