Ethinyl estradiol
Ethinyl Estradiol
Ethinyl estradiol (pronounced: eh-thin-ill ess-tra-dye-ol) is a synthetic form of estrogen that is often used in combination with progestins in contraceptive products. It is also used in hormone replacement therapy for transgender women.
Etymology
The term "ethinyl estradiol" is derived from its chemical structure. "Ethinyl" refers to the ethinyl group (C2H3) attached to the estradiol molecule. "Estradiol" is a type of estrogen, a hormone that plays a crucial role in the reproductive system.
Usage
Ethinyl estradiol is used in many different types of birth control pills, often in combination with a progestin. It works by preventing ovulation and by causing changes in the cervical mucus and the lining of the uterus, making it harder for sperm to reach the uterus and for a fertilized egg to attach to the uterus.
In addition to its use in contraception, ethinyl estradiol is also used in hormone replacement therapy for transgender women. It helps to develop and maintain female secondary sexual characteristics.
