What Does Having a Low Ovarian Reserve or Poor Ovarian Reserve Mean?

Every female right at the time of her birth has certain amount of eggs present in her ovaries which is termed as the Ovarian Reserve. This Ovarian Reserve diminishes with the passage of time but at any given point in time there are enough eggs in the ovaries required to easily reproduce when the female reaches the reproductive stage. In some females, this reserve of eggs or in other words the pool of eggs present in the ovaries is low than what the normal is. Such females are said to have a Low Ovarian Reserve. Such females find it difficult to get pregnant due to the low number of eggs present in their ovaries. This is usually the case in females above the age of 35 who try to get pregnant. Having a Low Ovarian Reserve does not mean that the patient has a dysfunctional ovary as ovarian function is not dependent on the number of eggs it has. Now, the important question to ask here is that what happens to all the eggs that were present previously. As stated, when a female is born, she is estimated to carry millions of eggs in her but with passage of time due to natural aging a lot of these eggs decay even before the female reaches the reproductive age. It is estimated that above the age of 35, a female has approximately about 30,000 eggs which further declines when the female reaches menopause. Under normal circumstances, the eggs present in a female is grouped into three categories of which one is a collection of immature eggs, one is a group of matured eggs which are ready for ovulation, and one is a group of dead eggs. Every month, there is a certain percent of eggs that get matured to ovulate of which one egg gets ovulated and the rest die and are reabsorbed by the ovary.
