LH: the norm in women. Luteinizing hormone: the norm on different days of the cycle

In men and women, a set of these chemicals, like hormones, is the same, but there are big differences in their quantity. Hormones release the pituitary gland and thyroid gland. They are rightly considered an invisible mechanism for controlling the entire body. After all, these substances affect a lot: the state of the hair and skin, the appearance of tumors, the flow of menstruation and menopause, the ability to have children, mood. In women, the production of hormones is much more difficult than that of men. The reason for this process is the cyclic functioning of the female body.

What is luteinizing hormone?

This hormone enters the body thanks to the pituitary gland. It regulates the activity of the sexual glands we have, namely stimulates the production of progesterone in the female body and testosterone in the male body.

This hormone is not always allocated in the same amount. In women, its production depends on the phase in which the ovulation cycle is located. The peak of its content in the body is ovulation; When this phase passes, its concentration decreases. The main task of LH is that it participates in the formation of the yellow body.

The main reasons for the shortage

LH can have different indicators throughout the cycle. When giving the tests, the doctor pays special attention to this. But why do you need to take tests and watch the concentration of this hormone? The fact is that with his shortage there are problems with the health of women and other troubles, which we will talk about later.

When there is a shortage of LH?

1. With an increased level of prolactin - hyperprolactinemia - the reverse content of LH is observed (the norm in women on day 2 of the cycle, as well as the subsequent days of the menstrual and follicular phase, can significantly exceed the hormone levels in the patient.) But in the first days of the cycle, namely, in the menstrual phase, Do not appoint, as the results may be unreliable).
2. If a woman has a luteal phase deficiency, then this behavior of the luteinizing hormone is observed.
3. With obesity.
4. With such a bad habit, like smoking.
5. If there were surgical interventions in the medical history of the woman.
6. With frequent stressful situations.
7. Also, a low content of LH in the blood is observed with some rare diseases.

Why is it a lot?

If there is a lot of luteinizing hormone in the body, it also affects the condition of the woman as a whole: her state of health, nervousness, the ability to have children, and so on. An elevated level of this substance in the blood is most likely indicative of the inadequacy of the performance of its functions by sex hormones, and there may also be a phenomenon such as ovarian depletion syndrome, pituitary tumor, endometriosis. Infectious diseases also affect its content. As a result, LH (a hormone) increases without control , the norm in women in this case differs significantly from the indices of the substance in the body according to the results of the analysis.

In addition to other rare diseases and listed reasons, the level of luteinizing hormone is affected by starvation, as well as debilitating, serious sports training. As we see, there are many reasons, because of which the concentration of LH in the blood changes. Taking certain medications also leads to an imbalance in the substance. It is necessary with special attention and caution to take preparations "Klomifen", "Naloxone", anticonvulsants and "Spironolactinum".

LH - the norm in women

The only way to know about the exact amount of LH in the body is the blood test for hormones. Such tests require special training. How to prepare for this laboratory study, we'll talk below, but now we'll figure it out, LG hormone - the norm in women what?

The greatest temptation for many of us is to interpret the results after getting them in our hands. If there is no specialist nearby, you can see the reference values of the content of this substance (that is, the LH norm in women). But do not get carried away with the interpretation, because only specially trained people with medical background know where the norm is, what your values mean and what to do with them now.

Most often, the reference values are distributed over the phases of the female cycle, but sometimes specialists study the phases every day. LH-norm or rate at women for 3 day of a cycle makes from 2,4 up to 12,6 mIU / ml. These indicators for each woman are individual, since each has its own amount of hormones released in principle. Some experts say that the norm is from 2 to 14 mIU / ml, but this should be dealt with by the doctor. Also, the luteinizing hormone content in the blood differs depending on the age. In girls and girls under 17, the lower threshold of the norm is always below 2 mIU / ml. It should be noted that the LH norm in women on the 5th day of the cycle at the beginning of the climacteric period differs significantly from that of women of reproductive age. It averages from 18 to 72 mIU / mL.

How does a woman detect the imbalance of this hormone?

Like many people living on the earth, we tend to go to the doctor as a last resort, when something is very troubling. Usual nervousness, weakness and extinct eyes, we often write off to problems in the family, work, lack of sleep and various stresses. These reasons are really many for everyone. But the problem can be hidden much deeper. Increased nervousness, abundant hair growth on different parts of the body, rapidly fading hair on the head, broad shoulders and affective conditions may indicate an increased or decreased level of LH levels, the rate of which in women also varies depending on the phase of the cycle.

How to take an analysis for the content in the body LH?

To determine the level of the hormone must be prepared in advance. First of all, for 3 days, physical activities and sports are excluded. Before taking the test, you can not smoke on average for 3 hours. The analysis is done on the 6.7 day of the cycle, if it is regular. The situation is more complicated with an irregular cycle. In the case of an irregular cycle, blood is taken from 8 to 18 days. Analysis of LH (the norm in women of which has already been prescribed) is given strictly on an empty stomach, you can drink only water. 8 hours before it, no food should enter the body. It is important to provide the patient 30 minutes before the study the state of rest, both physical and emotional.

Why do I need to take this analysis?

If the results of the analysis are different from those that are defined as an LH norm in women, this may indicate many pathologies in the body. It can be such diseases as infertility, menopause, Turner's syndrome and some others. To accurately determine the diagnosis, it is necessary, by meeting all the training requirements, to take the LH analysis. The norm for women on day 3 of the cycle will not significantly differ until day 14, so it makes no sense to take it a few days for the accuracy of the results, with the exception of an irregular cycle.
