What is FSH?
FSH - biologically active catalysts that are synthesized and secreted in the anterior segment of the pituitary. This hormone is responsible for the reproductive function, growth and pubertal maturation of the human body.
Prior to the onset of puberty in blood parameters FSH low. During the pubertal phase hormonal biosinterizovannye compounds are released from endocrine cells in the venous blood and lymph. The sex glands begin to develop, and there is hormone secretion. Follikulotropin penetrates into the circulatory system on the similarity of pulses at intervals 1-4 hours.
At half the fairer appearance FSH generates follicles, and in combination with lyuteotropinom stimulates the biosynthesis of estradiol.
When in the middle of the menstrual cycle follitropin level attainable peak, then ovulation takes place, the egg emerges from the ovary, because the ripe follicle bursts. During menopause fillikulotropina concentration increases, and it is associated with a reduction in estradiol.
When should I donate blood FSH
FSH rate of women by age is different. There is a special table on which you can define a normal result in a certain period of life. Test to determine the blood level of follicle-stimulating hormone is necessary to hand in the identification of various gynecological diseases, especially in female infertility.
If the doctor will fix that gonadotropins increased, and the number of sex steroids is much lower, it means a reduced activity of the gonads. The stern of the venous blood sample pass to determine the effectiveness of therapy in order to identify the menopause, as well as for the proper selection of oral contraceptives.
If the patient concerned the following reasons, it is directed to test the change:
- no pregnancy at a regular sexual life;
- absent ovulation;
- delayed puberty (earlier or later);
- vaginal bleeding arising from not orderly operation body;
- uterine growth mucosal layer;
- chronic inflammation of internal genital organs;
- prolonged menstruation or their absence;
- in the case of checking the action of hormonal agents in the body.
Preparation for analysis
FSH rate of women by age (table can explain all the results) is taken after a preliminary preparation for delivery.
To do this, follow these rules:
- Pass the test in the morning on an empty stomach, preferably from 8.00 to 10.00. Since the last food intake should be at least 8 hrs., And not more than 14 hours. Before analyzing the fence food should be healthy and in small portions.
- For 3-5 days before the study should abandon the intense exercise.
- The test is carried out on 5- 7 day cycle, before the delivery of psycho-emotional stress should be avoided, and the need to sleep well.
- In just a few days it is not recommended to drink spirits.
- It is forbidden to smoke at least 1.5 hours. prior to the diagnosis.
- Before the procedure is necessary to inform health workers on the eve of the medicines taken.
- Prior to blood sampling is not desirable to carry out other medical examinations (physical therapy and instrumental).
- Sometimes a study is conducted at the end of the cycle, and it is administered for 19-21 days.
How is the analysis of FSH
Venous blood was taken for the study on an empty stomach in the laboratory, the patient should be in a sitting or lying position. Due to the fact that FSH is released into the bloodstream irregularly, to obtain reliable results, taking 3 samples with an interval of 30 minutes.
On the procedure, it is desirable to come early to for 20-25 minutes. the body came to rest (waiting their turn, are encouraged to maintain calm and avoid active communication), as well as get rid of negative thoughts and emotions.
FSH is the norm in women over the age of
FSH rate of women by age, the table provides figures that correspond to a specific period of female life:
| Age component | Standard, mIU / ml |
| before puberty | 1,5-4,0 |
| The reproductive phase | 1,7-25,0 |
| Menopause | 140-150 |
The highest FSH figures recorded during the ovulatory process, and the ultimate decline recorded almost immediately after ovulation.
In girls before puberty and the appearance of menses level of follicle-stimulating hormone is low and does not vary cyclically. Growth of the enzyme starts after the first menses secretions. With the proper development of the organism follitropin values set on adult rates for the second menstruation.
Follitropin by the number present in the blood affect other active ingredients - estradiol, progesterone and testosterone. The higher the number, the lower the level of FSH and vice versa. This may explain why women in different periods of life follicle enzyme has a different content.
FSH changes depending on the phase of the menstrual cycle
FSH rate of women by age (table will help orient), namely, during the breeding season depends on the phase of the menstrual cycle.
| day cycle | Phase | Normal FSH (mIU / l) |
| 2-5 | menstrual | 3,5-12,5 |
| 5-13 | folikulyarnaya | 3,5-12,5 |
| 13-15 | ovulatory | 4,8-24,5 |
| From 15 to the beginning of menstruation | luteal | 1,6-9 |
Values follikulotropina fluctuates during the menstrual cycle, and regardless of how many days it lasts all it consists of 3 stages:
- follicular, Expressed most the maximum value of the enzyme. In the first 5-9 days. follicles ripen, and under the influence of gonadotropin increases only one of the total number. If FSH levels at this time increased, it can happen numerous ovulation with the release of several cells. In this case, the need for accurate diagnosis and concomitant medications.
- OvulationNow comes from the mature follicle egg.
- lutealIt differs fillikulotropina decline in activity due to the rupture of the pouch. Formed corpus luteum which produces progesterone.
Menstrual Phase 1 to day 6
At first monthly bleeding follicle-stimulating enzyme remains low, but from day 1, he quickly increases, and this creates fertile ground for the follicular maturation, and the most developed of them grows egg.
At the same time, the newly formed endometrium feeds on the blood and various nutrients. This process is necessary in order if in the case of successful conception, the egg in the uterus could take whatever she needed for further development.
Follicular phase, from 3 to 14 days
In this phase of the follicles are growing fast enough, and within them, due to high FSH, mature egg. Of all the elements of follicular only the largest can get into the subsequent monthly phase.
While developing the dominant follicle, increasing performance of other biologically active substances - estrogen, responsible for the development of the endometrium. Follicular phase lasts on average up to 2 weeks. Follikulotropin in this period is the same level as at the beginning of menstruation.
Ovulatory phase of from 13 to 15 day
This phase occurs in the middle of the menstrual cycle, and this time characterized by high levels of FSH, which coincides with the increase in luteinizing hormone. Through this follicle ruptures, and from there mature egg, which falls on the fallopian tubes into the uterus, and there meets with the sperm.
During this time, follicle stimulating hormone has a maximum value.
Luteal phase of 15 days before the beginning of menstruation
The follicle that has caused the appearance of the egg turns into yellow body and begins the luteal phase. Yellow iron begins to persistently produce progesterone which prevents the formation using pituitary gonadotropic enzymes.
If the egg is not fertilized in the womb, the yellow formation collapses, and progesterone decreased performance. Then the pituitary gland begins to produce FGS, in his blood counts are increased.
FSH in Pregnancy
At the stage of planning of pregnancy detection of FSH concentration in the blood is a must-see destination. It is necessary to determine ovulation, and to identify opportunities women bear fruit.
To advance the conception and development of successful pregnancy is not favorable as increased and reduced levels of the enzyme. Upon detection of deviations from specifications should be assigned additional diagnostics to identify the cause of deviations.
If a pregnant woman then fillikulotropina level is significantly reduced and may be up to 0.03 mIU / ml, which is the norm. This happens because in the state of pregnancy is no need in aging of the follicle and ovulation parish.
Here FSH secretion by the pituitary gland function decreases as compared with the standards of non-pregnant women in reproductive period. When child-bearing in the female body is estrogen growth, namely estradiol, which helps activate prolactin, FSH and the respective values are reduced.
After the birth of the baby the concentration of estrogen falls. Stabilization of hormone levels after the labor occurs in each person individually, and then the monthly cycle is restored regardless of lactation.
FSH menopause
Upon the occurrence of climacteric hormone fillikulostimuliruyuschego values are 9, 2 mIU / L to 126 mIU / l.
FSH indicators differ in different phases of menopause. Due to the fact that the levels of biologically active substances are interconnected, with a decrease in ovarian function in the estrogen content of the blood decreases, and this causes the release of follicle stimulating hormone. But because follicles are virtually absent, then no hormone exposure points, and it continues to spread in the blood.
Because the initial climacteric characteristic values fillikulostimuliruyuschego significant increase of the enzyme. At this point, FSH may be up to 135 mIU / l. After a couple of years, the body will adapt to this state and hormone falls to 18-55 mIU / L.
When you find the level of follicle stimulating hormone is also necessary to know the concentration of estrogen. If determined that the two values are increased, then it may indicate hormonopoietic tumors. It is also recommended to observe the dynamics of the movement of FSH, and if his performance does not decrease after a few years after the onset of menopause, it may indicate disease processes.
With the increase in the blood concentration of follicle stimulating enzyme women may have such complaints:
- tides, like the attacks of fever and nausea;
- palpitations, dizziness;
- an increase in weight due to fat deposits in the area of the thighs and the abdomen;
- changing the structure of the skin - decreased elasticity, and because of the high humidity reduces its peeling;
- It begins insomnia, and after a long sleep no feeling of relaxation;
- It is changing the mucosal epithelium, leading to painful urination, incontinence, and a feeling of dryness in the vagina.
The causes of variances
Excess or deficiency of FSH appears on the background of the influence of natural factors and the development of pathological processes. Daily changes of follicle enzyme - physiological effects.
To exclude false results to be patient a blood test 2-3 times. One of the main reasons for the rejection of the hypothalamus and pituitary and ovarian disease. There are also congenital disorders.
Low rates FSH
The reasons for low levels of follicle stimulating hormone:
- use of hormone and other drugs (cimetidine, clomiphene);
- pregnancy;
- dysfunction of the hypothalamus and pituitary gland;
- the availability of education in the ovaries;
- with deviations in iron metabolism;
- anorexia;
- postpartum initial phase;
- receiving anabolic, anticonvulsants and corticosteroids;
- stress;
- addicted to low-calorie diets.
A sign of low FSH may be scarce or monthly allocation complete cessation. In this case, women directed to a test to determine the blood concentration of the enzyme.
High rates of FSH
Increased performance levels of follicle-stimulating enzyme can mean:
- onset of menopause;
- early onset of disease, malnutrition or ovarian aging;
- absence of ovaries or any damage;
- certain forms of progressive hepatitis;
- renal failure;
- execution of radiotherapy;
- administration of drugs to treat diabetes, fungal infections, and drugs that reduce bad cholesterol;
- endometriosis;
- intoxication and experienced infection;
- alcoholism.
Quite often in women FSH increases with pathological abnormalities in the ovaries. In case of failures of their work pituitary emits large amounts of follitropin to maintain a stable level of active biological components in the body.
How to lower FSH?
Reduce the rate of follicle enzyme can be of the following methods:
- complex with vitamins take tsitaminy (specific means);
- normalize body weight;
- to give up alcohol and cigarettes;
- adherence to a diet that does not include the fatty and high-calorie food;
- moderate exercise;
- reduce the use of vegetable oils.
How to increase the FSH?
At low follicle-stimulating hormone egg is not matured, and artificial stimulation of ovulation can be corrected by means of hormonal preparations and injections. They take on an assignment scheme that takes into account the women's monthly cycle and the test results.
In addition to FSH drugs can increase the following ways:
- normalize the diet, taking into account the relevant amount of carbohydrates, proteins and fats;
- eliminate smoking and alcohol;
- avoid stress and fatigue;
- adjust diet, eat more foods that are beneficial to the work of the endocrine organs (cabbage, sea vegetation);
- sleep at least 7-8 hours. per day;
- reduce the intensity of physical exercise;
- to relieve nervousness several times a week to make herbal bath before going to bed;
- take a daily soothing herbal teas and teas, after consultation with a cardiologist;
- take nutritional supplements. For example, Vitex for 30 days;
- bring back to normal weight.
The ratio of FSH to LH (luteinizing hormone)
FSH rate of women by age (table shows the figures) in the ratio of LH:
| age period | The proportion of FSH / LH |
| Girls before puberty phase | 1:1 |
| In early menarche | 1:1,5 |
| reproductive age | 1:1,5-2,0 |
| climacteric | 1,5-2,0:1 |
During stable menstrual period ratio between a hormone has a specification and deviation from it may indicate the following:
| LH ratio FSGk | Note |
| 1:1,3 -2,5 | Norm |
| Less than 0.5 | The egg is not matured |
| More than 2.5 | The likelihood of polycystic ovaries |
To determine the proportion of one hormone to another investigating the blood serum.
Hormone levels can vary throughout a complete menstrual cycle, which is divided into 3 phases:
- follicular (1) - begins with the first day and lasts for up to 2 weeks;
- ovulatory (2) - bioactive substances produced by 12 or 14 days.
- luteal (3) - the remaining days.
hormone ratio to one another is determined only in the appointed days, which can be found in the table:
| Phase | Norm | Cycle days for passing the test | |
| FSH IU / ml | LC IU / ml | ||
| 1 | 1,38-9,9 | 1,69-15,0 | 7-9 |
| 2 | 6,18-17,19 | 22,0-56,6 | |
| 3 | 1,10-9,20 | 0,60-16,30 | 22-34 |
Based on the above figures, the expert knows the actual results, and can detect abnormalities woman.
Under what terms FSH is necessary to consult a doctor
If delivery of the analysis to determine the level of active compound has not been assigned a doctor, by the results obtained should consult a specialist.
In case of high concentration of the enzyme is necessary to consult a doctor. If the presence of the hormone in the blood is below the established norm, the test can be taken again. Only after repeated confirmation of low FSH is necessary to see a specialist.
Hormonal disorders an endocrinologist. When the existence of problems in the reproductive area (abdomen aches, unnatural selection) is desired visiting a gynecologist. When planning a pregnancy should go for consultation to the reproductive system.
Lowering follikulotropina it can be caused by natural factors (failure to comply with diet, alcohol intake, stress) and serious diseases.
FSH is a hormone not only affects the function of childbearing women, but also on the overall condition of the body. The norm is dependent on age, as indicated in the Table. To determine the index of the analysis. When deviations concentrations of follicle stimulating hormone, should consult a doctor to get advice on hormone levels in the body stabilization.
