Estriol (Oestriol): description, functions and role in the female body

Estriol (Oestriol) is one of the main female sex hormones that is synthesized in the ovaries. It belongs to the class of estrogens, which play an important role in regulating the female reproductive system.

Functions of estriol

The main function of estriol is to maintain pregnancy. It is produced in the placenta and is the main estrogen released during pregnancy. Estriol performs a number of important functions in the body of a pregnant woman, such as:

  1. Development of the female genital organs of the fetus;
  2. Maintaining blood circulation in the placenta;
  3. Preparing the mammary glands for lactation;
  4. Softening of ligaments and joints before childbirth;
  5. Regulating levels of other hormones such as progesterone.

Estriol is also involved in the regulation of the menstrual cycle and affects the general condition of the female body. It helps maintain healthy bones, skin and mucous membranes, improves mood and increases energy levels.

The role of estriol in the female body

Estriol plays an important role in the female body throughout a woman’s life. As we age, estrogen levels in the body decrease, which can lead to various health problems such as osteoporosis, menstrual irregularities, and vaginal dryness.

Estriol is often used as a hormone replacement therapy in menopausal women. It may help reduce symptoms associated with insufficient estrogen levels, such as hot flashes, sleep disturbances, and mood changes.

However, like any other drug, the use of estriol should only be done under the supervision of a physician, who will evaluate the indications and possible risks of its use.

Estriol is one of the female sex steroid hormones, secreted in the ovaries and responsible for the development of the uterus, vagina, mammary glands and other reproductive organs in women. It also plays an important role in regulating the menstrual cycle and preparing the body for pregnancy.

Estriol is produced from estradiol, which is the main female sex hormone, and its levels in a woman's body can vary depending on various factors such as age, pregnancy, menopause and other hormonal changes.

A lack of estriol can lead to menstrual irregularities, infertility, amenorrhea, osteoporosis and other diseases of the reproductive system.
