In women, it plays a key role in the development and functioning of the reproductive system, as well as in the growth of certain bones. It also governs the distribution of body fat in women and is the main hormone responsible for the fact that women are shorter than men, on average. Both the ovaries and the adrenal glands produce it.

The menstrual cycle in women involves predictable variations in the levels of several hormones, with estradiol being one of them. It is involved in the ovulation process and prepares the inner lining of the uterus for implantation, should the egg be fertilized. Certain tests done on baboons and other primates have indicated that his hormone also plays a continual role in maintaining a pregnancy, helping it to last for the full gestation period.

As a sex hormone, it also triggers many of the developments of the reproductive system that begin in puberty. It is present throughout the reproductive years, and declines during and after menopause. This decline is precisely what causes many of the symptoms of menopause, such as hot flashes and night sweats, vaginal dryness, and the loss of bone mass that may lead to osteoporosis.

Estradiol (E2 or 17β -estradiol) (also oestradiol) is a sex hormone.
Estradiol is the predominant sex hormone present in females. It is also present in males,
And at a higher level because it is being constantly produced.
In females it is only produced 3 out of 30 days of the cycle. It represents the major estrogen in humans.
Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs including the bones.
Estrogens direct the development of the female genotype in embryogenesis and at puberty. Estradiol is 
the major estrogen secreted by the premenopausal ovary. Estradiol benzoate is an estradiol analog 
which contains a benzyl ester at the C-3 position and is often used in combination with a progestin to 
induce estrus in domestic livestock. This compound binds to the human and murine estrogen receptor 
α (ERα), and chicken ER with IC50 values in the range of 22-28 nM. This reflects a 6-10 fold reduction 
in binding affinity compared to estradiol.
