Etynodiol diacetate, or ethynodiol diacetate, sold under the brand name Ovulen among others, is a progestin medication which is used in birth control pills.[4][5][6] The medication is available only in combination with an estrogen.[7] It is taken by mouth.[8]

Etynodiol diacetate is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[9][10] It has weak androgenic and estrogenic activity and no other important hormonal activity.[11][12][13] The medication is a prodrug of norethisterone in the body, with etynodiol occurring as an intermediate.[9][10][14]

Etynodiol, a related compound, was discovered in 1954, and etynodiol diacetate was introduced for medical use in 1965.[15][16] The combination ethynodiol with mestranol (Ovulen) was approved for medical use in the United States in 1966.[17] The combination ethinylestradiol with ethynodiol (Demulen) was approved for medical use in the United States in 1970.[18]

In 2021, the combination with ethinylestradiol was the 276th most commonly prescribed medication in the United States, with more than 800,000 prescriptions.[19][20]
