The two most important variables in female fertility are the egg quality and ovulation. Ovulation is the process of releasing the egg from the ovary which may be controlled by many variables. If the egg is not released, ovulation does not occur and pregnancy cannot be accomplished. If ovulation occurs, the egg has to be healthy to be fertilized, and develop into an embryo in order to implant and result in a healthy pregnancy. The most common cause of infertility in women with advanced reproductive age is compromised egg quality due to low ovarian (egg) reserve.
