Over 35? What You Need to Know

Fertility peaks for most women in their 20s and begins a gradual decline in the late 20s. But at age 35, that decline picks up speed. According to the American Society for Reproductive Medicine, there is about a 20 percent chance of a 30-year-old woman becoming pregnant in any given month. For a 40-year-old, that number drops to just 5 percent. Despite those statistics, and thanks to assisted reproductive technologies like In-Vitro Fertilization (IVF), the birth rate among women 40 to 44 years old is up six percent, according to the Centers for Disease Control & Prevention.
