title: Robinow's syndrome. Partial primary hypogonadism in pubertal boys, with persistence of micropenis.
abstract: We studied four patients with Robinow's syndrome. New findings included the following: (1) normal pubertal virilization with persistence of micropenis; (2) elevated basal serum follicle-stimulating hormone levels and a hyperresponse of serum  luteinizing  hormone to gonadorelin hydrochloride (Factrel) stimulation among postpubertal male patients, suggesting  partial primary hypogonadism; (3) normal 5 alpha-reductase and androgen receptor activity in genital skin fibroblasts; and (4) normal to borderline adult height.
