Abstract
Operative treatment of [human] microphallus has been proscribed in recent reports. It is not indicated for the more common endocrine type because of deficient gonadotropin, primary testicular disorder or end-organ defect. However, an operation may be quite necessary for the other form owing to defective morphogenesis-the anomalous type. Representative cases provide evidence that the method of treatment depends on the type of microphallus.
