The best treatment for cancer may lead to impaired fertility or the complete loss of fertility. However, rates of infertility vary depending on a number of factors, including cancer site, type of treatment, and the age of the patient.[2, 3] Infertility in cancer patients can be caused by the cancer or the type of cancer treatment received. Exact infertility rates are not known, because there are no valid measures for women to establish that fertility was present prior to treatment. Women who undergo chemotherapy or radiation for malignancies during reproductive years have a 40% to 80% chance of losing fertility.[3, 4] The treatments that produce the greatest risk for infertility include alkylating agents such as cyclophosphamide, methotrexate, and fluorouracil in chemotherapy; total body radiation; and external beam radiation in a field that includes the ovaries. Both chemotherapy and radiation can cause premature ovarian failure for females, often leading to premature menopause.
