External Genitalia

  • Michael K. FritschEmail author


The external genitalia of male and female fetuses are not commonly examined histologically. After birth, the external genitalia are examined grossly and usually designated as male, female, or ambiguous genitalia. Histologic examination of the external genitalia at the time of autopsy may be important in cases of cloacal abnormalities (more common in females) and in bladder outlet obstruction disorders, such as prune belly syndrome (more common in males). Therefore, understanding the histology of normal external male and female genitalia can be helpful in those rare cases when the external genitalia are abnormally formed.
