What is Ethynodiol?
Ethynodiol is a semisynthetic steroid having similar biophysiological effects as progesterone and administered with an estrogen as an oral contraceptive.
Oral contraceptives (also known as "the pill") are highly effective means of preventing pregnancy. Oral contraceptives consist of synthetic forms of two hormones produced naturally in the body: either progestin alone or estrogen and progestin. Estrogen and progestin regulate a woman's menstrual cycle, and the fluctuating levels of these hormones play an essential role in fertility.
Ethynodiol is usually used in combination with ethinyl estradiol, and sold under the trade names Demulen® and Zovia®.
