Ovarian overproduction of androgens is a condition in which the female ovaries make too much testosterone. This leads to the development of male characteristics in a woman. Other hormones, called androgens, from other parts of the body can also cause the development of male characteristics in women.
In healthy women, the ovaries and adrenal glands produce about 40 - 50% of the body's testosterone. Both tumors of the ovaries and polycystic ovary syndrome (PCOS) can cause excess androgen production.
Cushing's disease, an abnormality in the pituitary gland, causes excess amounts of corticosteroids, which cause masculine body changes in women. Also, tumors in the adrenal glands can cause overproduction of androgens and lead to male body characteristics in women.
Treatment depends on the problem that is causing the increased androgen production. Medications can be given to decrease hair production in patients who have excess body hair (hirsutism) or to regulate menstrual cycles. In some cases, surgery may be necessary to remove an ovarian or adrenal tumor.
The success of the treatment depends on what caused the excess androgen production. If the condition is caused by an ovarian tumor, surgical removal of the tumor may correct the problem. Most ovarian tumors are not cancerous (benign), and will not come back after they've been removed.
In polycystic ovary syndrome, the following can reduce symptoms caused by increased androgen levels:
Infertility and complications during pregnancy may occur.
Women with polycystic ovary syndrome may be at increased risk for:
There is no known prevention. Maintaining a normal weight through healthy diet and regular exercise can reduce your chances of any long-term complications.
