Medical uses[edit | edit source]

Etynodiol is used in combination with ethinylestradiol in birth control pills to prevent pregnancy. It works mainly by stopping the release of an egg during the menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg.

Side effects[edit | edit source]

Common side effects of etynodiol include nausea, bloating, breast tenderness, headache, change in vaginal discharge, mood swings, blurred vision, and changes in sexual desire. Serious side effects include blood clot, stroke, heart attack, and liver disease.

Pharmacology[edit | edit source]

Etynodiol is a progestogen, or an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has weak androgenic and glucocorticoid activity and no other important hormonal activity.

History[edit | edit source]

Etynodiol was discovered in 1954 and was introduced for medical use in 1965. It is sometimes referred to as a "first-generation" progestin.

Society and culture[edit | edit source]
