Lynestrenol is a progestogen structurally related to norethisterone; it is used singularly, or as the progestogenic component of oral contraceptives. It is also used in treatments for menstrual disorders. Lynestrenol is typically used as an oral contraceptive, but also for the treatment of menstrual disorders like: Oligo-menorrhea and hypo-menorrhea; Polymenorrhoea; Fibrocystic mastopathy; Endometriosis; Endometrial carcinoma and/or metastases etc. As a synthetic oral progestogen, Lynestrenol has similar effects as that of the natural progesterone hormone. It has a strong progestational effect on the uterine endometrium by transforming the proliferative endometrium into a secretory one. It also inhibits the secretion of gonadotropin, suppresses maturation of follicles in the ovaries and ovulation, and reduces menstrual bleeding. Lynestrenol has minimal estrogenic, androgenic and anabolic effects.

Lynestrenol markedly enhanced the lymphocyte response to phytohemagglutinin, the mixed lymphocyte culture, the active T-rosette test, the autologous red cell rosettes, and the number of nonadherent cells in the leukocyte adherence inhibition test. Lynestrenol also increased monocyte phagocytosis.
