Often, when screening for infertility requires the study of hormonal background of both spouses. This may seem surprising, but it is hormonal abnormalities often accompany infertility. If their time to identify and correct, the chance of pregnancy increases.
Becoming a customer at the center of Reproductive Medicine "Vera" you can pass a comprehensive examination on hormones: LH, FSH, prolactin, TSH, free T3, free T4, AT to TG, AT to TPO, Cortisol, DGA-s, St. Testosterone, Insulin, Estradiol - (Pass for 3-6 days of the menstrual cycle, progesterone - (rent 22-24 days of the menstrual cycle, in-hCG, CA-125, AMG 17-OHP
FSH - follicle stimulating hormone. In women, FSH is one of the main hormones that regulate the process of growth of the follicle (egg) in the ovaries and education under the influence of estrogen in the uterus which grows the endometrium. The maximum level of FSH is detected in the middle of the cycle that leads to ovulation. This hormone shall 3-7 (depending on the purpose of the study) days of the cycle. To determine if FSH follicle growth shall be 5-8 days.
In men, FSH is the main driver of growth of the seminiferous tubules. FSH increases the testosterone concentration in blood, thereby providing a process of sperm maturation. So what happens when the male testicles are small or have suffered from some kind of surgery or infection. For men, it is one of the four major sex hormones, which are a violation of separation, leads to disruption of reproductive function (the other three: LH, testosterone and prolactin)
LH - luteinizing hormone. Women provides completion of oocyte maturation in the follicle and ovulation. Just provide LH secretion of estrogen and the formation of the corpus luteum. In a series of women peak concentration of LH is necessary for ovulation, after which hormone levels drop and "holds" all the luteal phase at lower than in the follicular phase values. It is necessary to functioning corpus luteum in the ovary. During pregnancy, the concentration of LH is reduced. Rent as well as FSH 3-8 d.ts.
In men, stimulating the formation of binding globulin sex hormones, LH increases the permeability of the seminiferous tubules for testosterone. Thereby increasing the concentration of testosterone in the blood that promotes maturation of sperm.
One rather important criteria when screening for infertility, it is important ratio of LH and FSH. Normally, to the onset of menstruation, it is 1 year after the onset of menses - from 1 to 1.5, in a period of two years after the onset of menses and prior to menopause - from 1.5 to 2.
Prolactin. Prolactin is involved in ovulation, stimulates lactation postpartum. Therefore, it may inhibit the formation of FSH in the "right tselya" during pregnancy and unwanted in her absence. At elevated or reduced content of prolactin in the blood follicle may not develop, resulting in a woman's ovulation does not occur. Changes in the concentration of this hormone is only sufficient for the development of infertility.
To determine the level of this hormone is important to make the analysis in the phase 1 and 2 of the menstrual cycle and strictly only in the morning on an empty stomach. Immediately before taking the patient's blood should be able to rest for about 30 minutes because prolactin is a stress hormone and excitement or a small exercise can affect his level. In the luteal phase prolactin levels higher than in the follicular.
Elevated prolactin levels in men can disturb sexual function
Estradiol. Blood on the content of this hormone rent throughout the menstrual cycle. He has diverse effects on all the female genitals. Especially important is its role in the development of the mucous membrane of the uterus and its preparation for pregnancy. This hormone is secreted by mature follicles, the corpus luteum of the ovary, adrenal glands, and even fatty tissue under the influence of FSH, LH and prolactin. In women, estradiol provides formation and regulation of menstrual function, the development of the egg. Ovulation in women occurs within 24-36 hours after a significant peak estradiol. After ovulation, levels of the hormone decreases, there is a second, smaller in amplitude, rise. Then comes the decline in hormone concentration, which lasts until the end of the luteal phase.
Progesterone. This hormone is also called the "pregnancy hormone" because it provides the final preparation of the mucous membrane of the uterus for embryo attachment. Progesterone also provides optimal conditions for developing pregnancy.
This hormone is important to check on day 19-21 of the menstrual cycle.
Testosterone. This hormone can be checked and a man and a woman any day. Testosterone is needed both spouses, but it is a male sex hormone. In females, testosterone is secreted by the ovaries and adrenal glands. The excess of the normal concentration of testosterone in women can cause irregular ovulation and early miscarriage, and the maximum concentration of testosterone is defined in the luteal phase and during ovulation.
The man causes a decrease in testosterone levels as well, the lack of male power and reduced sperm quality.
DHEA-sulfate - hormone is one of the "male" sex hormone, which is produced in the adrenal glands in normal women in small quantities. When the concentration of this hormone is often a violation of the ovaries and infertility. DHEA-sulfate hormone can be checked and a man and a woman any day. He also needs a body of both spouses, but in different proportions.
Thyroid hormones (thyroxine - T4 and triiodothyronine - T 3) indirectly participate in the regulation of ovarian function. In thyroid diseases often develop infertility
T3 (Triiodothyronine) is produced by follicular cells of the thyroid gland under the control of thyroid stimulating hormone (TSH). Is a precursor to a more active hormone T4, but has its own, albeit less pronounced than that of the T4 action. Blood sample is taken on an empty stomach every day of the cycle. Immediately before taking the patient's blood should be able to rest for about 30 minutes.
T4 (Thyroxine total). This hormone increasing BMR increases oxygen consumption and heat production of all tissues of the body except the brain tissue, spleen and testis. Hormone levels in men and women in the rate remains relatively constant throughout life. However, in some areas, often observed decrease in the activity of the thyroid gland, which can lead to severe abnormalities in their own health and the health of the unborn child.
TSH (thyroid stimulating hormone) controls the operation of the thyroid gland. Changes in its concentration is a marker of thyroid disease. For any day of the cycle.
