If a woman experiences difficulties getting pregnant her gynecologist or obstetrician would usually recommend an ovarian reserve test. It includes taking urine and/ or blood samples for analysis to determine the levels of the hormones inhibin B, AMH, and FSH. When a woman’s egg count and quality diminish, the first two hormones usually decrease while the third tends to increase.
It is observed that women with normal ovarian reserve are more like to respond well to fertility treatments as compared to those with poorer reserves. The question is do the levels of those hormones impact the ability of a woman to get pregnant naturally.
A recent research shows that it is just as possible for the women with low AMH levels and those with high FSH levels to get pregnant as it is for those who have normal levels of AMH and FSH respectively. There are other factors involved. The individual levels of those hormones only indicate the ability of a woman’s ovaries to provide egg cells that can go through the process of fertilization to result in a healthy pregnancy. But there is no test that can measure either the number or the quality of the eggs a woman holds in her reserve.
Egg count cannot precisely predict the ability of a woman to get pregnant. Fertility can be affected by a number of factors and all should be taken into consideration by the doctor. Also, a number of factors can change the hormone levels test results, like taking birth control pills, or conditions like an ovarian cyst or obesity.
An ovarian reserve test involves a blood and/or a urine analysis test to determine the levels of the hormones inhibin B, AMH, and FSH. However, a study proved that the levels of AMH, FSH, and inhibin B had no effect on both the women who got pregnant and on those who couldn’t.
