Infertility: Overview and Risk Factors

Infertility is defined as the inability to become pregnant after one year of unprotected intercourse. It is a common medical condition, affecting about 15 percent of couples in the United States.

About 40 percent of cases are a result of female infertility. Twenty to 30 percent of cases are due to male infertility. In 15 to 20 percent of cases, no underlying cause can be identified.

Infertility may occur as a result of several disease states, many of which are influenced by diet and exercise. Couples that follow healthful diets, exercise, and maintain healthy weights are less likely to experience medical problems that impair fertility.
