The most important biological componentshuman body, which control not only our feelings and behavior, but virtually all the physiological processes, are hormones. Prolactin in women is the main hormone responsible for the childbearing function that regulates ovulation and the menstrual cycle. It is about him today's article.
So, prolactin (hormone): what is it? What is his norm? What is the response of the hormone prolactin in the human body? Let's look at these questions.
Prolactin is produced in the brain, andnamely in the anterior pituitary gland. It is also called the "stress hormone", as the increase in its level is observed under various physical and emotional strains.
Scientists are still studying prolactin (a hormone). What it is is not fully known today. In the course of numerous studies, the following functions of this biologically active substance in the female body were established:
For a male body, this hormone is also very important, because:
It follows that prolactin has a hugeinfluence on the condition of the reproductive system, both women and men. In addition, the hormone is a natural "contraceptive" - prevents conception during pregnancy and breastfeeding.
The level of this hormone varies depending on the day of the menstrual cycle. The following values are considered normal values:
During the gestation of the baby, serious changes occur in the woman's body, and the prolactin hormone also changes. The norm for women during this period is:
The increase in the level of the hormone prolactin beginsat the 8th week of pregnancy. Its maximum value is observed at 20-25 weeks. Before birth, the content of prolactin decreases. The next increase in the hormone occurs during breastfeeding.
As already mentioned above, one of the main roles in the body of the male members is the hormone prolactin. The norm for men is slightly lower than for women, and is in the range of 2.5-17 ng / ml.
A blood test will help determine the contentin the body of a substance such as the hormone prolactin. When to take tests? Women are advised to donate blood during the first 3 days of the menstrual cycle (unless there are any specific recommendations). The most favorable period for determining the hormone prolactin - this morning, after awakening should take 2-3 hours. Analyzes are usually given up on an empty stomach.
The day before you need to donate bloodhormone prolactin, should refrain from sexual contact, refuse to visit saunas, baths, exclude the use of alcohol, even in minimal doses. Any disturbances and experiences contribute to an increase in the content of the substance in the blood, so if possible, exclude stressful situations on the eve of the analysis. Before the investigation, be extremely careful and do not allow injury to the chest. Immediately before the analysis, lie down for 30 minutes and try to relax as much as possible. For an hour before taking blood refrain from smoking. To comply with the above recommendations is very important. Otherwise, the results of the blood test will be unreliable, which will entail the surrender of other analyzes.
Experts recommend conducting a blood test for prolactin, if a woman has the following pathologies:
Men should be tested for prolactin if:
This is a pathological condition characterized by various diseases, namely:
In addition, the level of the hormone can be increasedwith severe renal pathology, liver cirrhosis, neoplasm in the hypothalamus, taking certain medications that have a corresponding side effect (estrogens, hormonal contraceptives, tricyclic antidepressants, amphetamines, and others).
Hyperprolactinaemia can also have a physiological character. The level of prolactin rises when:
With an excess of the hormone prolactin in the body, there are serious functional disorders (both in men and women):
In addition, a high content of hormoneprolactin in the blood can cause loss of vision, sleep and memory disorders, depression, osteoporosis, mastopathy, provoke such a dangerous condition as oncology of the mammary glands or other important female organs.
If a specialist diagnoses an increasedthe content of prolactin in the body, treatment should begin immediately. Therapeutic measures are aimed at combating the disease, which caused the development of hyperprolactinaemia. Thus, prolactinoma presupposes drug treatment with the use of a drug such as Bromocriptine and other drugs, radiotherapy of a pituitary tumor, or its removal by surgery. When hypothyroidism is necessary treatment of thyroid pathology, and so on.
Reduced concentration of this hormone inbody is considered a variant of the norm for children, men and non-pregnant women. Reducing the amount of prolactin in the blood, as a rule, does not require special treatment. However, to exclude the pituitary diseases, to undergo a medical examination is still worth it.
Reduced levels of prolactin in the blood may indicate:
Also, the level of the hormone under consideration decreases as a result of radiotherapy of the pituitary tumor, prolonged use of certain medications (Dopamine, Levodol, etc.).
Today you learned more about such an important substance as prolactin (hormone): what it is, what functions it performs in the human body, on which the rise or fall of its level in the blood depends.
To prevent possible problems,it is necessary to monitor your health very closely, to react in a timely manner to the slightest deviations from the normal state. Women's health, as well as men, is of great importance. It is on him that the birth of children, a normal relationship with a partner and a happy family life.
