Age is the most important factor affecting a woman's fertility. A woman's eggs will also decline in quality and quantity with age. A woman in her mid-20s has up to a 30 percent chance of getting pregnant each month. Fertility usually begins to decline in a woman's late 30s and declines more sharply after age 35. By age 40, the chance of getting pregnant in any given monthly cycle is about 5%. In this article, we will provide useful information about graphs showing the effect of age on fertility in women.
