Ethinyl estradiol, also sometimes written as 17α-ethinyl estradiol, ethinylestradiol, ethynyl estradiol, or ethinyl œstradiol, is a derivative of 17β-estradiol (E2), the major endogenous estro-gen in humans. EE2 is an orally bioactive estro-gen used in many formulations of combined oral contraceptive pills and is one of the most commonly used medications for this purpose.

Transdermal ethinyl estradiol carries a greater risk of clot formation and venous thromboembolism than naturally occurring 17β-estradiol, which some have theorized to be related to different amounts of hepatic metabolism after absorption. The same contraindications and precautions apply for EE2 as with other estro-gen medications.

Estinyl was a preparation of EE2 alone that was used for the management of menopausal symptoms and female hypogonadism.

EE2 is released into the environment as a xenoestro-gen from the urine and feces of people who take it as a medication.

The major concern with unopposed estro-gen (without progestogen) is of endometrial cancer. As such, the medication is generally prescribed with progesterone in the setting of birth control.
