Common causes and risk factors
Many factors can contribute to female infertility. Frequent causes include ovulation disorders (such as polycystic ovary syndrome or premature ovarian insufficiency), tubal problems from pelvic infections or surgery, uterine abnormalities (fibroids, intrauterine adhesions), endometriosis, and advancing maternal age. Lifestyle and general health — tobacco, very high or low body weight, heavy alcohol use, and some chronic conditions — also affect fertility. A male factor is equally important; evaluations are often performed for both partners.
