AMH analysis
The analysis of ovarian stock is an analysis used to measure the level of the hormone AMH, which is produced by reproductive tissues in humans, including the testes in males, and ovaries in females, and the examination of ovarian stock is not considered one of the routine tests that are examined in laboratories This test is useful in evaluating ovarian functionAnd the estimation of the remaining time of pregnancy, as it gives an indication of the ovarian reserve, and the contents of the eggs, and therefore this examination is important in estimating and predicting menopause, and it may also be requested when a woman suffers from symptoms of Polycystic Ovary Syndrome . Sometimes it is performed when a woman undergoes certain treatments, as is the case in the treatment of ovarian cancer, and in IVF techniques (in Vitro Fertilization). Others, such as the test for estradiol and follicle stimulating hormone, and vaginal ultrasound examination. It should be noted that it may be performed in certain cases for children, as is the case when the doctor suspects that the testicles of a male child are not present, or that they are not working properly, in addition to other cases such as infants who do not have clear genitals, that is, It is difficult to determine whether an infant is male or female.

AMH levels
It is possible to measure AMH levels by a simple blood test in medical laboratories, and blood is drawn during the days of the menstrual cycle , and when the results of the examination appear, it is determined whether the level of the hormone is within normal, low or high limits, and then the doctor studies the results, and arrives at A diagnosis of the condition, and below are some details of the results of the AMH hormone analysis: [2]
- The hormone is considered to be within high levels if the result is greater than 5 ng / ml.
- The hormone is considered to be within the upper permissible limit . If the result is between 3.5-5 ng / ml.
- The hormone is considered within normal limits; If the result is between 0.7-3.5 ng / ml.
- The hormone is considered to be within the minimum permissible level . If the result is between 0.3-0.7 ng / ml.
- The hormone is considered to be at low levels. If the result is less than 0.3 ng / ml.
Causes of low AMH level
In fact, females are born with about 2 million eggs in the ovaries, and with the passage of time the eggs are constantly lost, as the number of most women at puberty is about 400 thousand eggs, and by the age of thirty, this number will decrease to 27 thousand eggs. Menopause may only reach a thousand eggs, but it is worth noting that the rate of decrease in eggs may differ from one woman to another, and it should be noted that the smaller the egg stock, the lower the AMH value, and due to the decrease in the ovarian stock in women, several factors we mention among them : [3]
- Natural aging that constitutes most cases of low ovarian reserve.
- Genetic defects; As the presence of defects in the X chromosome.
- Medical treatments that could harm the reproductive system; Such as: radiation treatments for cancer.
- Ovarian surgery; As in Alantbaz endometriosis known as the lining of the uterus migrating.
- Smoking .
- Unknown reasons; That is, there is no clear cause that explains this situation.
IVF and AMH
In some cases of delayed childbearing, women may resort to assisted reproductive technologies, such as; In vitro fertilization , and in such operations, an analysis of the AMH level may be required before starting the operation, because knowing the hormone levels will reveal important information, regarding the quality of the eggs in the ovaries, for women who have a high AMH level, This indicates that they have a lot of healthy eggs left, and they often show a better response, and produce good eggs when stimulating the ovaries, for IVF. Where there are many studies that have been conducted, and it has revealed that women who have high levels of the hormone AMH, have a 2.5 times greater chance of success in IVF compared to other women of a similar age, with low levels of the hormone, and in general it can be said that the production of a greater number Of eggs during an operationArtificial fertilization is associated with better results. [4]
Other tests
In addition to measuring AMH, there are other analyzes of some hormones that may help doctors assess a woman's fertility level , and give her an indication about the likelihood of a normal pregnancy occurring with her, or if she needs medical intervention for pregnancy, as in cases of IVF, and others. These results shall give indications of the likelihood of success or failure of the process, and conducting these tests will give a more comprehensive picture of the health status of women 's reproductive, the following mention of some of these analyzes: [5]
- Follicle stimulating hormone (FSH) analysis: This hormone affects the ovarian follicles, as it regulates the menstrual cycle, and works to stimulate the production of eggs in the ovaries.
- Luteinizing hormone (LH): Increasing the level of LH signals the ovaries to release an egg. Therefore, this test is used to evaluate a woman's ovulation process, and it can also determine whether a woman has reached menopause or not.
- Estradiol: Estradiol is one of the most important types of estrogen hormones , and this hormone test is useful in evaluating ovarian function, and it should be known that the appropriate time for this test should be between the third and fifth day of the menstrual cycle .
