Mechanism of action

Estradiol valerate is an estrogen that provides estrogenic activity, while dienogest is a progestin that suppresses the luteinizing hormone (LH) surge necessary for ovulation. Together, they create a hormonal environment that prevents follicle development and ovulation, and also thickens cervical mucus to impede sperm penetration. This combination is used in oral contraceptive formulations.
