Sertoli-Leydig cell tumors are a cancer that starts in the female ovaries. The cancer cells produce and release a male sex hormone which may cause the development of male physical characteristics (virilization), including facial hair and a deep voice. This type of tumor is sometimes called arrhenoblastoma of the ovary or a stromal tumor. Sertoli-Leydig cell tumors are rare tumors which account for less than 0.5% of all ovarian tumors. While they can be found in women of all age groups, they are most common in young women. Treatment involves surgery and chemotherapy or radiation if the cancer has spread. Because Sertoli-Leydig cell tumors have a low chance of spreading, if the tumor is found early, chances for survival are good.
