Hormones during pregnancy planning |List and the rate of hormones during pregnancy planning

balance of hormones in the female body changes periodically, so it is very important to check blood on hormones during pregnancy planning.After all of the required hormone levels may depend on the very possibility of conception, as well as the normal course of gestation process.

In particular, attention should be paid to changes in hormonal levels to those women who have previously been observed menstrual disorders, pregnancy failed, or a couple can not conceive a child for a long time.

What hormones should be checked when planning pregnancy?

What hormones should be checked when planning pregnancy?How does a particular hormone is the ability to get pregnant?

to start with a list of hormones during pregnancy planning, the level of which is recommended to check the specialists, gynecologists, reproductive system.

  • Estradiol.
  • Progesterone.
  • FSH.
  • LH.
  • Testosterone.
  • Prolactin.
  • Thyroid hormones.
  • DHEA-S.

women after 30 years when planning a pregnancy can also be assigned to AMH analysis.

hormones list when planning a pregnancy

Consider what kind of hormones for which they are responsible, and why do we need to know about their numbers.

Estradiol - the amount of this hormone in the female body is not constant and depends on the monthly phases.Estradiol is synthesized in adipose tissue and in ovarian follicles and influenced by other hormones - LH and FSH.Under the influence of estradiol, the uterus prepares for implantation, there is a natural growth of the endometrial layer.The most common blood estradiol take 2-5 or 21-22 day cycle.Analysis of the rent on an empty stomach in the morning, on the eve can not eat fatty foods, drink alcohol, smoke or engage in heavy physical labor.

Progesterone - This hormone is synthesized by the ovaries and to a lesser extent - by the adrenal glands.In pregnant women, the placenta synthesizes progesterone.It helps implantation of the egg, stimulates an increase in the uterus during pregnancy, protects it from excessive contractile activity that contributes to the preservation of the fetus in the uterus.Analysis for taking hormone during ovulation (approximately 14 days) and after 22 days depending on the length of the menstrual cycle.Venous blood for analysis pass in the morning before a meal.

follicle-stimulating hormone (FSH) - activates follicular development and the production of estrogen in the body.The normal level of the hormone promotes ovulation.Blood studies for rent for 2-5 or 20-21 days of the menstrual cycle, on an empty stomach.

Luteinizing hormone (LH) - together with follicle stimulating hormone participates in the growth of follicles, ovulation, corpus luteum formation.The peak number of hormone observed during ovulation, when pregnancy LH level goes down.Assay for LH administered, usually along with FSH, as one without the other malopokazatelen hormone.Far more important to determine the quality ratio of the two hormones.On the norms will be discussed below hormonal parameters.

Testosterone - is considered to be a male sex hormone, although it is formed, and a woman in the ovaries and adrenal glands.High hormone levels can disrupt the process of ovulation and cause miscarriage in early pregnancy.The greatest amount of hormone produced in the body during the luteal phase and in the ovulatory period.

Prolactin - a hormone synthesized in the pituitary gland.It ensures the development of the mammary glands in females, stimulates the production of breast milk.The amount of this hormone closely related to the amount of the estrogen and thyroid hormones.Analysis of charge in the morning before a meal.One day before the analysis is not recommended to have sex and to stimulate the mammary glands, as well as not to be nervous, since because of this hormone rates can be high.Most often rent prolactin 5-8 day cycle.

Thyroid hormones - they must take all patients who were treated to the doctor with menstrual cycle disorders, with miscarriage or unsuccessful attempts to become pregnant.First of all, we need parameters thyroid stimulating hormone (TSH), and, at the physician's discretion, free T4 and T3.TSH hormone is involved in the stimulation of prolactin, a hormone necessary for pregnancy.Disorders of the thyroid gland work can adversely affect ovulation and function of the corpus luteum.

DHEA-S - adrenal hormone, androgen, its name stands for dehydroepiandrosterone sulfate.Due to this hormone in a pregnant woman's placenta begins to develop estrogen.Analysis of this hormone are often used for the diagnosis of ovarian pathology.Serum was taken on an empty stomach, one day eliminate the use of alcohol and fatty foods, and a half hours before the study can not smoke and exercise.

level antimyullerovogo hormone (AMH) is checked, mainly women, who are planning a pregnancy after 30 years.As is well known, women's ovaries can not produce infinitely follicles, and sooner or later their reserves run low, independently pregnant woman can not.So the amount of AMH determines ovarian ovarian reserve, ie indicate how likely follicle maturation and ovulation offensive and suggests the possibility of occurrence of early menopause.

Norma hormones during pregnancy planning

Estradiol (E2):

  • in the follicular phase - 12,5-166,0 pg / ml;
  • in the ovulatory phase - 85,8-498,0 pg / ml;

  • menopause - to 54.7 pg / mL.

Progesterone:

  • in the follicular phase - 0.2-1.5 ng / ml;
  • in the ovulatory phase - 0.8-3.0 ng / ml;
  • in the luteal phase - 1,7-27,0 ng / ml;
  • menopause - 0.1-0.8 ng / ml.

Follicle stimulating hormone:

  • in the follicular phase - 3,5-12,5 mIU / mL;

  • in the luteal phase - 1,7-7,7 mIU / mL;
  • menopause - 25,8-134,8 mIU / mL.

Luteinizing hormone:

To determine the ratio of FSH / LH ratio of FSH required to share in the ratio of LH.The resulting value should correspond to:

  • 12 months after puberty - from 1 to 1.5;
  • 2 years after puberty and before menopause - from 1.5 to 2.

  • women during pregnancy - from 34 to 386 ng / mL.

Thyroid-stimulating hormone (TSH, thyroid hormone TSH) - 0,27-4,2 mkIE / ml.

free thyroxine (thyroid hormone FT4) - 0,93-1,7 ng / dL.

DHEA-S, performance standards:

  • in women 18 to 30 years - 77,7-473,6 mg / dL;

reference values ​​can be different in different laboratories, so the interpretation of the results and the diagnosis should be carried out only by your treating doctor.

Hormones before planning pregnancy: abnormal

Excess estradiol standards may indicate:

  • continued existence nesovulirovavshego follicle;
  • presence of endometrial cysts appendages;
  • Tumour appendages capable of secretion of hormones.

fall in the rate of estradiol:

  • by smoking;
  • at high physical exertion, unusual for the body;
  • at elevated prolactin;
  • with inadequate luteal phase;
  • at danger of spontaneous abortion of hormonal etiology.

Excess progesterone standards may indicate:

  • pregnancy;
  • risk of uterine bleeding;
  • violation placenta formation;
  • disease of the adrenal glands and kidneys;
  • presence of cystic formation of the corpus luteum.

progesterone indicators Lowering:

  • anovulatory cycle;
  • disorder of the corpus luteum functionality;
  • chronic inflammatory process in appendages.

Violation ratio of FSH and LH may indicate a lack of the pituitary gland, hypothyroidism, syndrome of amenorrhea, or renal failure.

Increasing testosterone levels can be a sign:

  • strengthen adrenal function;
  • tumor appendages;
  • hereditary predisposition.

Reduced testosterone indicators can speak about the following situations:

  • presence of endometriosis;
  • high estrogen content;
  • development of uterine fibroids or breast cancer;
  • osteoporosis.

Elevated levels of prolactin may be observed in such pathologies:

  • pituitary tumor;
  • low thyroid function (hypothyroidism);
  • polycystic appendages;
  • anorexia;
  • liver and kidney disease.

low prolactin levels is noteworthy only in cases when its performance is reduced compared to other hormones (eg, thyroid hormones).This may indicate a pituitary disease.

Thyroid hormone can be increased:

  • in renal failure;
  • in tumors;
  • with certain diseases of the psyche.

lowering TSH levels can indicate:

  • violation of the thyroid gland works;
  • pituitary injury.

increased amount of thyroxine indicates the presence of hyperthyroidism and low - hypothyroidism.

increased amount of DHEA-S refers to the phenomenon of increased androgen production due to disruption of the adrenal glands: this may cause inability to tolerate pregnancy.

Reduced rate antimyullerovogo hormone shows:

  • of menopause;
  • of reduced ovarian reserve;
  • depletion ovaries;
  • obesity.

increased amount of AMH may occur:

  • with anovulatory infertility;
  • with polycystic ovaries;
  • for tumors of the appendages;
  • at LH receptors violations.

Women who are planning a healthy pregnancy, to carry out a study of blood can have 3-6 months prior to the proposed conception attempts.

appoint and evaluate tests on hormones can only be a qualified doctor gynecologist or reproductive system.Pass hormones when planning pregnancy can almost all modern clinics and laboratories.
