What's Ethynyl Estradiol?
Ethinyl estradiol (EE) also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl œstradiol, is a derivative of 17β-estradiol (E2), the major endogenous estrogen in humans. EE is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills. It is one of the most commonly used medications for this purpose.
Ethinylestradiol is used to supplement or replace the body's natural oestrogen. It helps to relieve many of the problems associated with the menopause, such as hot flushes, night sweats and vaginal dryness. It can also help to protect against osteoporosis although other treatments are usually preferred for this.
Ethynyl Estradiol Application:
1) used to prevent pregnancy. It contains 2 hormones: a progestin and an estrogen. It works mainly by preventing the release of an egg during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg and changes the lining of the uterus to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body.
2) preventing pregnancy, birth control pills may make your periods more regular, decrease blood loss and painful periods, decrease your risk of ovarian cysts, and also treat acne.
3) Ethinyl Estradiol is a semisynthetic estrogen. Ethinyl estradiol binds to the estrogen receptor complex and enters the nucleus, activating DNA transcription of genes involved in estrogenic cellular responses. This agent also inhibits 5-alpha reductase in epididymal tissue, which lowers testosterone levels and may delay progression of prostatic cancer. In addition to its antineoplastic effects, ethinyl estradiol protects against osteoporosis. In animal models, short-term therapy with this agent has been shown to provide long-term protection against breast cancer, mimicking the antitumor effects of pregnancy.
