ICD-10 Specific code N80.9: Endometriosis, unspecified

Danazol is a synthetic steroid derived from ethisterone an is indicated for the treatment of endometriosis and benign fibrocystic breast disease.

Dienogest is a nortestosterone derivative with no androgenic but rather an antiandrogenic activity of approximately one third of that of cyproterone acetate. Dienogest binds to the progesterone receptor of the human uterus with only 10% of the relative affinity of progesterone.

Dydrogesterone is an orally-active progestogen having an activity comparable to parenterally administered progesterone.

Goserelin is a synthetic analogue of naturally occurring LHRH. On chronic administration goserelin results in inhibition of pituitary LH secretion leading to a fall in serum testosterone concentrations in males and serum estradiol concentrations in females.

Leuprorelin is inactive when given orally due to poor membrane permeability and an almost complete inactivation by intestinal proteolytic enzymes. Leuprorelin has potent LHRH agonist properties when given during short-term and intermittent therapy, however, when administered in a continuous, nonpulsatile manner, LHRH analogs induce inhibition of gonadotropin secretion and suppression of testicular steroidogenesis.

Medroxyprogesterone acetate exerts anti-oestrogenic, anti-androgenic and antigonadotrophic effects.

Norethisterone has progestational actions similar to those of progesterone, but is a more potent inhibitor of ovulation and has weak oestrogenic and androgenic properties. It is used to treat a number of disorders of the menstrual cycle.
