Ovarian reserve is an indicator of the individual stock of eggs in the ovary, which is laid in every woman before birth. By the time of birth, the girl has 5 to 7 million eggs in the ovaries. By the onset of the first menstrual period, 300-500 thousand eggs remain. And further, during the entire reproductive period, a woman only “loses” her eggs at each ovulation.
Contrary to the widespread notion that only one egg is consumed in the menstrual cycle, it has been found out that several dozens of egg cells start up in each menstrual cycle, and only one, as a rule, actually ovulates. The rest perish.
A reduced ovarian reserve indicates that the woman has a noticeably reduced supply of eggs in the ovary and the chance of becoming pregnant is reduced. It should be borne in mind that each biological age corresponds to its own ovarian reserve. Therefore, the biological age does not always correspond to the actual one: it can both “lag behind” and “overtake” it.
The analysis for an ovarian reserve is obtaining information on a stock of the eggs that are in a woman’s ovary by a certain age.
With a decrease in the stock of eggs, the chances of a successful IVF result also decrease. At the same time for the onset of pregnancy may require 3-5 and even more attempts.
