To determine and timely treatment of gynecological diseases in women often prescribed an analysis of hormones. In this case, the most commonly performed determination of the level of luteinizing hormone, progesterone, prolactin.
Luteinizing hormone (LH) belongs to adrenal hormones synthesized by the anterior pituitary gland. It is this hormone that stimulates the production of estrogens in the female body and regulates the secretion of progesterone and is directly involved in the formation of the yellow body.
Such an analysis for female sex hormones is mandatory if:
- Decreased libido;
- Polycystic Ovary Syndrome;
- Sexual Infantilism

Like any submission of tests for the definition of female hormones, LH analysis requires preparation. Before taking the test at the level of LH, 72 hours before the procedure, women are advised to completely rule out physical activity and exercise. Blood is only taken on an empty stomach and on the 7th day of the menstrual cycle.
Normal indicators of this hormone for women differ and depend on the phase of the menstrual cycle. Thus, in the follicular phase, its concentration is 1.1-11.6 mU/ml, in the ovulation phase – 17-77. In the luteal phase, the concentration level does not exceed 14.7. It should also be noted that the intake of oral contraceptives reduces the level of this hormone to 8.0 mU/ml.
What is an analysis for progesterone?
Among the analyzes for female hormones, most often an analysis is performed to determine the level of progesterone in the blood. It is produced directly by the yellow body and is acutely necessary for the normal course of pregnancy. Progesterone prepares the preparation of the uterine endometrium, with which the fertilized egg can be implanted.

The analysis is performed on the 22nd to 23rd day of menstruation of a woman’s cycle, while direct blood is done in the morning on an empty stomach. In cases where the girl is not tested in the morning, the fence can be done during the day, but not earlier than 6 hours after eating.
the hormone levels are different: 0.32-2.23 nmol/L – in the follicular phase and 6.99-56.63, – of the luteal.
What is the purpose of analyzing prolactin in the body?
The hormone prolactin participates directly in the process of formation and development of the mammary glands and stimulates the production of milk in them during lactation.
Such an analysis will be assigned if:
- cyclic pain in the mammary glands;
- breast disease;
- Violation of ovulation and its absence;
- Absence of monthly;
- Diagnosis of infertility;
- Injury of lactation after birth;
Before you take the test, the woman should exclude for one-day sexual contacts, as well as thermal influence on an organism (a bath, a sauna). In addition, stress conditions directly affect the level of the hormone prolactin in the blood.
A blood sample will be for 3 hours after the blood-as the woman woke up. Immediately before the procedure, you need to rest for 10-15 minutes in front of the office and calm down. The normal level of prolactin in women is 109-557 mU/l.
Thus, which tests are also performed for female hormones, a preparatory preparation for them is necessary.
