Description

Estrogens direct the development of the female genotype in embryogenesis and at puberty. Estradiol is the major estrogen secreted by the premenopausal ovary.¹ Ethynyl estradiol is a synthetic analog of estradiol used commonly as an oral contraceptive, often in combination with a progestin such as norgestrel/levonorgestrel or desogestrel. Efficacy of oral administration of ethynyl estradiol is facilitated by the ethynyl substitution at the C-17 position, which inhibits first pass hepatic metabolism. Ethynyl estradiol is also rapidly and almost completely absorbed from the gastrointestinal tract.²
