Mechanism of action

Ethinylestradiol is a synthetic estrogen and levonorgestrel is a synthetic progestin. Together they suppress the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) surges needed for ovulation. The progestin component also increases cervical mucus viscosity to impede sperm transport. The placebo tablets in the pack contain no active ingredients and allow for withdrawal bleeding during the hormone-free interval.
