Arrhenoblastoma
En Español (Spanish Version)

Definition
An arrhenoblastoma is a rare type of ovarian tumor. This tumor primarily secretes the male sex hormone, testosterone, and rarely the female sex hormone, estrogen.

Arrhenoblastomas are generally benign, meaning they do not normally spread beyond the ovary.

Treatment
Treatment involves surgery to remove one or both ovaries. This procedure is usually successful in returning normal menstruation (in premenopausal women) and ceasing masculinization. If the tumor is late stage and particularly aggressive (which is rare), radiation therapy , chemotherapy , or both, in addition to surgery, may be needed.

Prevention
