Etynodiol (INN), or ethynodiol (BAN), is a steroidal progestin which was never marketed.[1][2] A diacylated derivative, etynodiol diacetate, is used as a hormonal contraceptive.[1][2]

While etynodiol is sometimes used as a synonym for etynodiol diacetate, what is usually being referred to is actually etynodiol diacetate and not etynodiol.
