Ovarian Aging and Infertility
The decrease in female fecundity beginning after the age of 30 and exaggerated after 40 is a well documented finding. This age-related decline in fertility is the result of several factors that contribute to overall reproductive failure. Women over 35 require a longer period to achieve conception than younger women, and a higher percentage of older women will never achieve pregnancy. In addition, the rate of early pregnancy wastage increases substantially during the 30s, and is over 50% after age 40.
