Infertility is a disease that affects the reproductive organs of both men and women. It impairs one of the body’s most basic functions—the ability to have children. Infertility affects about 6.1 million women and men in the United States alone—10 percent of the reproductive-age population.
Unlike other disease like lung cancer or HIV/AIDS, people are rarely informed of the very direct links between their behavior and their reproductive health. Smoking, sexually transmitted infections, age, and an unhealthy body weight can increase risks of infertility.
