Mechanism of action

The progestin desogestrel inhibits the luteinizing hormone (LH) surge necessary for ovulation, while ethinyl estradiol suppresses follicle-stimulating hormone (FSH) to prevent follicle development. Together, these hormones also thicken cervical mucus and alter the endometrium to create a hostile environment for sperm and implantation.
