Luteinizing hormone in women
Luteinizing hormone plays an important role in the reproductive capacity of women. It is produced by the anterior pituitary gland and is responsible for the function of the reproductive system. During the menstrual cycle, its level is almost always low, except for the pre-ovulatory period, when the luteinizing hormone rises almost tenfold and reaches its peak. Due to this, the ovulation process starts, the dominant follicle is torn, and the egg cell ready for fertilization comes out of it. Ovulation tests, by which a woman planning a pregnancy, will be able to determine the most favorable time for conception, are based on the principle of determining elevated levels of LH in the body. Ovulation occurs 12-48 hours after the bright second strip appears on the test.
When do I need to determine the level of LH?
However, this happens in a woman’s ideal menstrual cycle. But often we have to deal with some abnormalities in which it is necessary to take an analysis for luteinizing hormone in order to reliably diagnose and prescribe the correct treatment:
- too short or too long cycles, lack of menstruation;
- Anovulation on ultrasound examinations;
- primary or secondary infertility;
- breakthrough uterine bleeding;
- polycystic ovary syndrome:
- preparation for in vitro fertilization.
How to get a reliable result?
- LH is surrendered on strictly defined days: on the 3-5th and on the 19-21st days of the menstrual cycle.
- The analysis is given on an empty stomach, on the eve of eliminated alcohol and smoking.
- Try to reduce physical and emotional stress 48 hours before delivery.
The rates of LH are determined individually by the laboratory in which you have taken the analysis. Therefore, with the results, be sure to go to a doctor who, based on age, gender and other criteria, will determine your personal normal level. If it turns out that luteinizing hormone is elevated, your doctor may suspect that you have the following diseases:
- Polycystic ovary syndrome.
- Inflammation of the pituitary gland.
- Ovarian depletion.
- Kidney problems.
If the luteinizing hormone is below normal or is at its lower limit, then this may be due to:
In any case, the diagnosis is not made on the basis of only an analysis of luteinizing hormone. Examination should take place in the complex of tests for other hormones, ultrasound and other means. Treatment is also prescribed based on the cause, which contributed to the decrease or increase in the level of LH in the blood. It is obvious that it is very important to monitor your hormonal background and timely diagnose your health. Diseases identified at the initial stage are treated quickly and effectively.
