Estradiol is the most potent and predominant form of estrogen in the human body. It is a steroid hormone that is essential for sexual and reproductive development, mainly in women.
Some key points about estradiol:
- Produced primarily by the ovaries, estradiol plays a vital role in the menstrual cycle, fertility, and pregnancy.
- It regulates the growth and function of the female reproductive organs like the uterus, cervix, fallopian tubes and vagina. Estradiol thickens the endometrium (uterine lining) to prepare for a potential pregnancy.
- Together with other hormones, estradiol influences bone growth and helps maintain bone density. It also affects cardiovascular health and plays a subtle role in lipid metabolism.
- Estradiol levels fluctuate through the menstrual cycle - higher prior to ovulation and lower during menstruation. Declining estradiol levels are responsible for perimenopausal and menopause symptoms as women age.
- Abnormal estradiol levels may indicate issues like ovarian cysts, endometriosis, uterine fibroids or cancers. Hormone testing can determine if levels are within normal ranges.
- Synthetic versions of estradiol are present in many contraceptive formulations like oral contraceptive pills, vaginal rings and patches. As hormone therapy, it helps relieve menopausal symptoms like hot flashes in middle-aged women.
