Estradiol is the most potent and predominant form of estrogen - the primary female sex hormone. It plays a vital role in the development and regulation of the female reproductive system and secondary sex characteristics.
Estradiol is produced primarily by the ovaries, adrenal glands, and fat tissues in women. Smaller amounts are also produced in men's testes and adrenal glands. It circulates in the bloodstream and binds to estrogen receptors in various tissues throughout the body.
Some key functions of estradiol include:
Abnormal estradiol levels can indicate issues like polycystic ovary syndrome (PCOS), ovarian failure, tumors, or menopause in women. Deficiency can cause infertility, osteoporosis, heart disease risks to rise.
So in summary, estradiol is an integral sex hormone that coordinates many aspects of female health. Tracking its levels ensures normal biological and reproductive processes. Supplementing when low or interacting with receptors may alleviate certain conditions. Consult endocrinologists if this critical estrogen is too high or low.
