What causes infertility in women?

Women need functioning ovaries, fallopian tubes, and a uterus to get pregnant. Conditions affecting any one of these organs can contribute to female infertility. Some of these conditions are listed below and can be evaluated using a number of different tests.

• Polycystic ovary syndrome (PCOS): PCOS is a condition that causes women to not ovulate, or to ovulate irregularly. Some women with PCOS have elevated levels of testosterone, which can cause acne and excess hair growth. PCOS is the most common cause of female infertility.
• Diminished ovarian reserve (DOR): Women are born with all of the eggs that they will ever have, and a woman’s egg count decreases over time. Diminished ovarian reserve is a condition in which there are fewer eggs remaining in the ovaries than normal.
• Functional hypothalamic amenorrhea (FHA). FHA is a condition caused by excessive exercise, stress, or low body weight. It is sometimes associated with eating disorders such as anorexia.
• Premature ovarian insufficiency (POI). POI, sometimes referred to as premature menopause, occurs when a woman’s ovaries fail before she is 40 years of age. Although certain exposures, such as chemotherapy or pelvic radiation therapy, and certain medical conditions may cause POI, the cause is often unexplained.
• Menopause Menopause is an age-appropriate decline in ovarian function that usually occurs around age 50. By definition, a woman in menopause has not had a period in one year. She may experience hot flashes, mood changes, difficulty sleeping, and other symptoms as well.
