ABSTRACT
Development of the external genitalia is a complex process in
the male, which predisposes to many congenital anomalies.
Understanding these anomalies requires a detailed knowledge
of the embryology, and particularly the central roles of
androgens (in coordinating the masculinization of the
anatomy) and the processus vaginalis (which allows descent
of the intra-abdominal fetal testis into the scrotum).
