What does it do?

Ethinyl estradiol is a synthetic component of the estrogen class, a reproductive hormone in women. It is mainly included in oral contraceptives for the purpose of preventing pregnancy. This component helps regulate the menstrual cycle in women.

Ethinyl estradiol acts on the hypothalamus and pituitary gland in the brain to inhibit ovulation. It also modifies the endometrium to make it difficult for a fertilized egg to implant. As a result, pregnancy is prevented.

Approved uses differ by product. Check each product's information for its actual use.
