Estradiol (Oestradiol)

Estradiol: the main female sex hormone

Estradiol (Oestradiol) is the main female sex hormone that is produced in the ovaries. It belongs to the class of estrogens, which play an important role in female reproductive health, as well as in a number of other physiological processes.

Functions of estradiol

Estradiol performs several key functions in a woman's body. First, it regulates the growth and development of the female reproductive organs, including the uterus, ovaries and vagina. It is also involved in regulating the menstrual cycle and maintaining pregnancy.

In addition, estradiol affects bone health, helping to keep them strong and healthy. It may also affect blood cholesterol levels and heart health.

Lack of estradiol

A lack of estradiol can lead to a number of health problems, including bone diseases such as osteoporosis and cardiovascular problems. Low estradiol levels can also lead to premature aging of the skin and mucous membranes.

Excess estradiol

On the other hand, excess estradiol can lead to various health problems, including breast, endometrial and ovarian cancer. Excess estradiol can also be associated with circulatory problems such as thrombosis.

Use of estradiol in medicine

Estradiol can be used medicinally to treat a variety of health problems, including symptoms of menopause, osteoporosis, and some types of cancer. Estradiol may also be used to control reproductive health.

In custody

Estradiol (Oestradiol) is an important female sex hormone that plays an important role in women's reproductive health and in a number of other physiological processes. Too little or too much estradiol can have serious health consequences, so it's important to maintain normal levels. If you have health problems related to estradiol, contact your doctor for advice and treatment.



Estradiol is the main female reproductive hormonal product that is necessary for the proper functioning of the woman’s body. Estradiol is equally important in the reproductive system and in other systems of the human body, such as bones, skin, heart and brain. This hormone is active in women throughout all periods of life - puberty, menopause, during pregnancy, during lactation and, of course, during sexual arousal.

Estradiol is produced by the ovaries. Physiologically, estradiol is released under the influence of FSH (follicle stimulating hormone), while estrogen is produced by the adrenal glands in response to testosterone, and lutein is produced by the corpus luteum in the ovary. Thanks to this interaction, these hormones normalize hormonal regulation and function of the fertilized egg.

The formed estradiol is distributed throughout the body through the bloodstream and is found in almost all organs and tissues. Regardless of the phase of the menstrual cycle, this hormone is responsible for regulating the tissue of the uterus, ovaries, mammary glands and bones. Estradinol continuously interacts with estrogen, enhancing its effect and at the same time protecting the egg all the way to the uterus. In turn, estradizole protects estrogen molecules from intoxication by suppressing the enzymatic decomposition of its receptors.
