Ethinylestradiol is a synthetic derivative of estradiol, which is a naturally occurring form of estrogen. It is commonly used as a component in combination oral contraceptives (birth control pills) along with a progestin. Ethinylestradiol works by mimicking the effects of endogenous estrogen in the body, which helps to suppress ovulation, inhibit the maturation of eggs, and create changes in the cervical mucus that make it more difficult for sperm to reach the uterus. In addition to its contraceptive effects, ethinylestradiol is sometimes prescribed for hormone replacement therapy (HRT) in postmenopausal women to alleviate symptoms of menopause, such as hot flashes and vaginal dryness. It is important for individuals using ethinylestradiol-containing medications to follow their healthcare providers instructions carefully due to potential side effects and interactions with other medications.
