Estradiol is the major estrogen secreted by the premenopausal ovary. Ethynyl estradiol is a synthetic analog of 17 β-estradiol. 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.
