Mechanism of action

Ethinylestradiol is a synthetic estrogen and levonorgestrel is a synthetic progestin. Together, they provide negative feedback to the hypothalamic-pituitary-ovarian axis, preventing follicle-stimulating hormone (FSH) and LH secretion. This dual hormonal action prevents ovulation, thickens cervical mucus to impede sperm transport, and alters the endometrium to reduce implantation likelihood.
