title: Biliary atresia with hyperandrogenic amenorrhea: case report.
abstract: The etiology of hyperandrogenic amenorrhea in a 16 year-old girl after a successful Kasai operation for biliary atresia was unclear. Delayed puberty and menarche were observed. There was no luteinizing hormone-follicular stimulating hormone surge. A provocative luteinizing hormone-releasing hormone test showed a normal response. Peripheral aromatization of androgens appeared to function normally. However, plasma levels of sex hormone-binding globulin and total testosterone were high and the free testosterone level was normal. The anovulatory menstrual cycle continued after menarche at 18 years of age. A combination of estrogen and progesterone therapy was effective. The etiology might be associated with delayed metabolic clearance of testosterone accompanied by the compensatory cirrhosis and portosystemic shunt.
