Estradiol - the norm in women

Estradiol - a female hormone, which is judged on the function of the ovaries. He is responsible for the maturation of structures that determine the secondary sexual characteristics of a woman. Probably, you are wondering why estradiol is considered the "main" estrogen in a woman's body, if there are two more hormones with very similar functions? The thing is that the activity of estradiol is 80 times higher than that of estriol and estrone combined! That is why, the dosage of estradiol can give the doctor the correct information about the status of the hormonal background of a woman and about the function of her ovaries.

Estradiol - the norm in women

It will be fair to note that the norm of estradiol in women is a relative term. After all, the indicators of estradiol are strictly dependent on the phase of the menstrual cycle, and also they vary greatly during pregnancy.

Next, we give the norms of estradiol in women, and we will make some clarifications as to the hormonal background during the menstrual cycle and pregnancy.

On the day of the onset of menstruation, the follicular phase of the cycle starts - the dominant hormone is follicle-stimulating. He directs the growth of one of the eggs, which is encapsulated in the follicle. In the middle of the cycle, when the follicle is sufficiently developed, it begins to produce estrogens. Then, within 36 hours, ovulation occurs. After the "adult" egg leaves the bursted follicle, the concentration of estradiol significantly decreases.

So, the norms of estradiol in women:

When a woman becomes pregnant, the function of producing the hormone estradiol is taken over by the placenta. Below, we give weekly estradiol values ​​in a pregnant woman.

Elevated estradiol in women

The level of estradiol in women is checked by means of a blood test. If the rates of estradiol in your body are high - it indicates a malfunction with the ovaries. Perhaps you have problems with regard to conception of the child or the results of infertility treatment remain unsatisfactory. If you are on hormonal treatment, it is very important to notify your physician about it.

What is the danger of an elevated level of estradiol in women?

It has been proven that high levels of estradiol in women are often associated with a risk of endometrial cancer (the inner layer of the uterus). In addition, increased rates of estradiol in women are associated with risk of stroke and breast cancer. If you notice numbness of one side of the body, redness and heat in one or both breasts, changes in the form of a nipple - see a doctor as soon as possible and give the test for estradiol.

Reduced estradiol in women

Reduced estradiol in women - the situation is not so common, can cause a serious "headache" in planning pregnancy.

As we noted above, a high level of estradiol during the cycle stimulates the process of "bursting" of the follicle and the process of ovulation. Consequently, when there is a shortage of estrogen, ovulation does not take place, and a woman can not become pregnant.

The classic manifestation of estradiol deficiency is polycystic ovary syndrome.

Also, after a long intake of oral contraceptives, which cause a low level of estradiol, the endometrium is thinned. This prevents the normal introduction of a fertilized egg into the uterus.

Fortunately, there is a therapy that adjusts the level of estradiol and helps women become pregnant.
