If the ovaries produce too much androgen (male hormones such as testosterone) a woman may develop male characteristics. This ovarian imbalance can be caused by tumors in the ovaries or adrenal glands, or polycystic ovarian disease. Virilization may include growth of excess body and facial hair, amenorrhea (loss of menstrual period) and changes in body contour.
