If a period of 6-12 months, the pair did not manage to conceive a child, it is necessary to be surveyed. Gynecologists recommend to make sure there are no infections and hormonal check. To do this, it is important to understand what hormones need to pass when planning pregnancy.
Why to be tested
Gynecologists all women before pregnancy is recommended to hand over the general blood tests, urine and check for infections, sexually transmitted diseases. Some patients still need to be tested for hormones.
This survey reveals hormonal disorders and to establish the cause of infertility in women who failed to conceive within a year.
Timely detection of hormonal disruption can prevent the occurrence of complications during pregnancy.
Check before conception gynecologists advise patients who have:
- menstrual irregularities;
- previously missed abortion, miscarriage;
- increased body weight;
- there were signs of hyperandrogenism (hirsutism male pattern, deepening of voice);
- chronic diseases that can affect the hormonal balance.
Also, doctors are advised to undergo an examination for all women older than 35 years. At this age, ovarian activity decreases, it affects the level of hormones in the body. Analyzes reveal the existing problems, the survey gynecologist can choose corrective treatment.
What tests will pass
To test the hormones, you need to understand which tests for hormones in the planning should be returned. List of surveys chosen physician, considering the patient's history, its health status, weight loss or signs of hyperandrogenism.
FSH
Follicle stimulating hormone responsible for follicular growth, oocyte maturation process and its yield in the fallopian tube. It affects estrogen synthesis and creates favorable conditions for ovulation.
FSH is produced in the pituitary gland, ovaries it enters the bloodstream. The blood hormone is released regularly, so you need to be tested to verify its level at 2-4 day cycle. To determine the period of oocyte maturation can donate blood to FSH on day 5-8 of the menstrual cycle.
Increasing its level is possible if the patient:
- endometriosis;
- pituitary tumor;
- disrupted ovarian.
Reduced FSH observed in polycystic ovaries, over- or under-weight.
LH
In the first phase of the cycle simultaneously with follicle gynecologists recommend check the level of luteinizing hormone. They are interrelated: the action of FSH and LH ovulation occurs and begins to form the corpus luteum. LH reaches the maximum level during the release of the egg from the follicle.
If you violate the ratio of FSH and luteinizing hormone levels need to check the operation of the pituitary gland.
In such a situation, a woman can not ripen and release of the egg. These analyzes on hormones when planning pregnancy can detect the cause of infertility.
Elevated levels of LH may occur upon depletion of the ovaries and ovulatory disorders. LH decreased in patients with obesity, pituitary tumors. It may be lower than normal in women who are in prolonged stress.
prolactin
For pituitary prolactin is responsible. This hormone is necessary for the preparation of the breasts for milk production. Additionally, he is responsible for the reduction of pain in childbirth and stimulates the beginning of breathing in infants.
Increase of prolactin is one of the causes of infertility, because it triggers the growth FSH concentration decrease and suppress release of an egg from the follicle process. prolactin level depends not only on the phase of the cycle, but also on the time of day. Minimum performance will be in the morning, and the maximum - in the night.
The level of this hormone may increase in patients who have:
- pituitary tumor;
- absent ovulation;
- underweight;
- liver disease and urinary system;
- problems with the functioning of the thyroid gland.
The reduced concentration of prolactin is rare. Such a situation is possible with pituitary disease.
Suspected that the patient has elevated prolactin, can be on circumstantial evidence:
- vaginal dryness;
- discharge from the breasts;
- blurred vision;
- delay menses.
To obtain reliable results, you need a positive attitude at the time of analyzes. Against the background of stress prolactin increases.
Progesterone
One of the mandatory tests for women who can not conceive, is to determine progesterone content. Its deficiency can lead to the fact that the fertilized egg can not gain a foothold in the uterus. Progesterone contributes to the growth of the endometrium and formation of the medium favorable for the embryo implantation. Even if the pregnancy, when progesterone deficiency increases the risk of miscarriage or fetal stop.
It is best suited for the delivery of the progesterone phase 2. Analysis desirable to schedule at 21-23 days from the beginning of menstruation. In mid phase two of its level rises to the maximum value. With irregular cycle analysis better to hand several times after ovulation has passed.
Donate blood at the planning stage it is recommended to patients who have disrupted menstrual cycles, or they are painful. Also check the levels of progesterone should be women with acyclic uterine bleeding.
estradiol
Under the influence of luteinizing hormone and follicle-stimulating hormone in the ovaries produce estradiol. He is responsible for the development of the uterus, fallopian tubes, uterine cavity preparation for fetal implantation and intensity of blood loss during menstruation. Its maximum level is observed for 1-3 days before ovulation.
Gynecologists recommend to take this analysis to women who can not get pregnant for more than 6 months in a row.
Better to do it on a 2-5 or 21-23 day cycle.
Estradiol reduced when anovulation increase prolactin, excessive physical stress. Increase possible when tumors or cysts appendages.
DHEA-sulphate
The women said hormone is produced in small quantities. It is recommended to take if there is a suspicion of ovarian pathology. DHEA-sulfate rent in any day of the cycle.
Increasing the level of this male hormone in the female body is possible with adrenal tumors or other diseases of these organs. A decrease is observed in long-term use of steroid hormones.
Testosterone
In the ovaries and adrenal glands in small amounts produced by the male hormone testosterone. Increase in its number of triggers ovulation disorders. To determine the level of the hormone analysis may take on any cycle day after menses.
On increasing evidence deepening of voice, male pattern hair growth (the appearance of hair on his chest, face). Its growth is possible in case of tumors of the appendages or reinforced the adrenal glands.
AMG
Developing antimyullerova hormone begins immediately after the birth of a girl and ends after menopause. At its level does not affect the power or the image of a woman's life. Patients older than 30 years who did not get to conceive a child, it is recommended to check the AMG. It displays the follicular reserve and the likelihood of ovulation. Antimyullerova by the level of the hormone can be assumed during menopause.
With the depletion of ovarian androgens, polycystic changes in AMH level changes. By deviation from the norm can cause disorders of sexual development, obesity.
Thyroid hormones
A woman's ability to conceive and nurturing of the child depends on the functioning of the thyroid gland. If its functioning is disturbed, it can cause problems with conceiving a child. If you suspect that there are problems gynecologist may recommend a patient, are planning a pregnancy, to be tested for thyroid hormones.
Check level of thyroid stimulating hormone (TSH), thyroxine (T3), 17-ketosteroids, cortisol, triiodothyronine (T4). Assays for the hormones pass preferably not later 10 am. Prior to that, you can not eat, drink, tea, coffee, soft drinks. You should also stop taking iodine-containing drugs, and hormonal agents a week before the survey.
Thyroid-stimulating hormone is responsible for the production of prolactin. TTG content decreases in renal failure patients, psychiatric diseases, tumors and hypothyroidism. When injury of the pituitary and malfunctions Thyroid TSH concentration may increase.
Triiodothyronine influence on the metabolic processes responsible for the enrichment of oxygen to tissues. TSH is produced simultaneously with thyroxine. Synthesized T3 effect on protein metabolism, tissue oxygenation.
What to do with deviations
If the results of tests revealed failures in the hormonal system, assigned a special therapy. The doctor may recommend medications to appoint a diet or advise lifestyle changes. In some cases, only surgery can eliminate the cause of hormonal failure.
In the appointment of hormonal treatment of the patient's condition is monitored over time. therapy scheme is adjusted if necessary.
