Female age is the most significant factor that affects the success of infertility treatment. As a woman’s age advances, it leads to a drop in the ovarian reserve and a deterioration in egg quality. The rate of fertility decreases with each passing year, particularly after the age of 35, and reaches to its maximum after the age of 40. Eggs obtained from women over 40 often exhibit a high incidence of chromosomal abnormalities. This hinders embryo implantation and significantly increases the risk of miscarriage in resulting pregnancies.
