Hirsutism and virilization.
In normal females, androstenedione from both the adrenal cortex and ovary, as a result of peripheral conversion, is the source of the majority of biologically active testosterone in the circulation. The control of the secretion of precursor steroid and androgenic hormone (testosterone) in females is not clear at this time. There are a number of possibilities to explain various types of hirsutism and virilization. The presence of true virilization indicates a significant disorder and requires complete investigation. The presence of increased amounts of 17-ketosteroids in the urine implicates the adrenal cortex as a source of the pathologic manifestations. The suppressibility of elevated 17-ketosteroids with cortisol analogues aids in distinguishing between adrenal hyperplasia and autonomous neoplasm of the adrenal cortex. By far the most common entity in this area is simple hirsutism without virilization. Although our knowledge of this disorder is quite incomplete, conservative management is indicated. Further progress in this field is rapidly occurring. An informed clinician can do an adequate job of diagnosis and treatment with the clinical and laboratory tools generally available.
