Conspicuous External Genitals in the Boy

  • Georges L. Kaiser


Many and diverse pathologies manifest as conspicuous external genitals. The visible genitals may be assigned to a boy or a girl, or assignment occurs first to a wrong sex or is not possible at all (ambiguous external genitals). Therefore, classification in one of the three groups (male or female conspicuous external genitals, and external genitals in disorders of sex development) may be impossible at the first look because effacement of the clinical presentation does not render a correct delineation. In Table 32.1, most relevant pathologies that lead to conspicuous external genitals in the boy are listed and differentiated according to their clinical significance.
