It is important to be aware that egg quality and quantity do not always go hand in hand. Both conditioning factors should therefore be treated separately.
When talking about quantity, remember that women are born with a finite number of oocytes. Throughout a woman’s life and during her fertile years, consumption is inevitable up to menopause. This is known as the ovarian reserve. This reserve, i.e., the quantity, can be measured through analysis of the Anti-Müllerian hormone, along with other analytical tests such as FSH, estradiol or antral follicle count.
However, sometimes, even when there is good ovarian reserve when counted, these follicles are empty or do not develop normally, and the oocyte, which is the cell that must mature in the follicle wall each month until ovulation, does not grow or abnormalities are found in its DNA structure. This is what is referred to as poor egg quality.
