I view a program on Discovery condition over the weekend. Health Investigators... or something approaching that. Anyway, they be reviewing the grip of a woman that did not menstrate. She have superior than conventional level of testostorne also. I will not even pretend to know the diagnosis... nearby be two possiblities. One from the ovaries over producing testosterone, and the other be cause by... oh crap, very soon I can't deliberate. Anyway, in that is another (part) gland(?) surrounded by females that produces trace amounts of testosterone. In this program, when they discovered what be cause the illustrious level and treated as expected, the woman begin have a regular cycle.
