Ethinyl Estradiol (EE) is a synthetic estrogen with the chemical formula C20H24O2 and a molecular weight of 296.41 g/mol. It is a potent derivative of 17β-estradiol, modified by the addition of an ethynyl group at the C17α position, enhancing its oral bioavailability and resistance to metabolic degradation. EE is widely used in hormonal contraceptives, hormone replacement therapy (HRT), and the treatment of estrogen-deficient conditions.

 

1. Contraception: Acts as a key component in combined oral contraceptive pills (COCs) by inhibiting ovulation through suppression of  LH and follicle-stimulating hormone (FSH).
2. Hormone Replacement Therapy: Administered to alleviate menopausal symptoms (e.g., hot flashes, vaginal dryness) and prevent osteoporosis in postmenopausal women.
3. Oncology: Utilized in treating estrogen receptor-positive breast cancer (postmenopausal women) and prostate cancer (via androgen suppression).

1. Endocrine Regulation: Binds to estrogen receptors (ERα/ERβ) to modulate gene transcription, influencing reproductive, skeletal, and cardiovascular systems.
2. Menstrual Cycle Control: Suppresses secretion, thereby preventing follicular development and ovulation.
3. Metabolic Effects: Enhances hepatic synthesis of sex hormone-binding globulin (SHBG) and thyroxine-binding globulin (TBG), impacting thyroid and sex hormone metabolism.
