List of hormones in pregnancy planning
Consider what kind of hormones they are, what they answer for, and why we need to know about their quantity.
Estradiol - the amount of this hormone in the female body is unstable and depends on the monthly phase. Estradiol is synthesized in adipose tissue, as well as in ovaries and follicles under the influence of other hormones - LH and FSH. Under the influence of estradiol, the uterine cavity is prepared for implantation, a natural growth of the endometrial layer occurs. Most often, the blood for estradiol is taken at 2-5 or on the 21-22 day of the cycle. The analysis is taken in the morning on an empty stomach, on the eve you can not eat fatty foods, take alcohol, smoke and engage in heavy physical labor.
Progesterone - this hormone is synthesized by the ovaries and in a smaller amount by the adrenal glands. In pregnant women, progesterone synthesizes the placenta. It helps implant the egg, activates the uterus during pregnancy, protects it from excessive contractile activity, which contributes to the preservation of the fetus in the uterus. The analysis for the hormone is taken during ovulation (approximately on day 14), and also after 22 days, depending on the duration of the monthly cycle. Venous blood for analysis is taken in the morning before meals.
Follicle-stimulating hormone (FSH) - activates the development of follicles and the production of estrogens in the body. The normal level of this hormone contributes to ovulation. Blood for study is given for 2-5 or 20-21 days of the monthly cycle, on an empty stomach.
Luteinizing hormone (LH) - together with follicle-stimulating hormone takes part in the growth of follicles, ovulation, the formation of the yellow body of the ovaries. The peak amount of the hormone is observed during ovulation, while during pregnancy LH levels decrease. The analysis on LH is prescribed, as a rule, along with FSH, since one hormone without another is of little indication. It is much more important to determine the quality of the ratio of the two hormones. We will talk about the norms of hormonal parameters below.
Testosterone - is rightly considered a male sex hormone, although it is formed in a woman, in the ovaries and adrenal glands. A high level of hormone can disrupt the process of ovulation and provoke miscarriage in the early stages. The greatest amount of the hormone in the body is formed during the luteal phase and in the ovulatory period.
Prolactin is a hormone synthesized in the pituitary gland. It provides development of mammary glands in women, activates the production of breast milk. The amount of this hormone is closely related to the amount of estrogens and thyroid hormones. The analysis is taken in the morning before meals. The day before the analysis is not recommended to have sex and stimulate the mammary glands, and also not to be nervous, because because of this, the hormone levels can be high. Most often, prolactin is given on the 5th-8th day of the cycle.
Thyroid hormones - they must be given to all patients who turn to a doctor with violations of the monthly cycle, with miscarriage or unsuccessful attempts to become pregnant. First of all, we need the indices of thyroid-stimulating hormone (TSH), and, at the doctor's discretion, free T4 and T3. The hormone TTG takes part in stimulating the production of prolactin, the necessary hormone for pregnancy. Disorders in the functioning of the thyroid gland can adversely affect ovulation and the functioning of the yellow body.
DHEA-S - adrenal hormone, androgen, its name stands for dehydroepiandrosterone sulfate. Thanks to this hormone, a pregnant woman starts producing estrogen by the placenta. Analysis for this hormone is often used to diagnose the pathology of the ovaries. Blood serum is taken on an empty stomach, for 24 hours alcoholic drinks and fatty foods are excluded, for an hour and a half before the study you can not smoke and exercise.
The level of anti-Muller hormone (AMG) is checked, mainly, in women who plan pregnancy after 30 years. As is known, female ovaries can not indefinitely produce follicles, and sooner or later their reserve runs low, a woman can not become pregnant herself. So the amount of AMG determines the ovarian reserve of the ovaries, that is, indicates how likely the maturation of the follicles and the onset of ovulation, and also indicates the possibility of early menopause.
