AB Atypical  genitalia  are  present  when  the  sex  of  an  infant  is  not  readily  apparent  after  examination  of  the  external  genitalia.  If  the  appearance  resembles  neither  a  male  with  a  normal  phallus  and  palpable  testes  nor  a  female  with  an  unfused  vaginal  orifice  and  absence  of  an  enlarged  phallic  structure,  the  genitalia  are  atypical,  and  investigation  before  gender  assignment  is  indicated.  These  conditions  are  now  referred  to  as  disorders  of  sex  development  (DSDs,  more  recently  also  as  differences  in  sex  development).  The  term  atypical  genitalia  instead  of  ambiguous  genitalia  has  been  suggested.  Definitions  and  classifications  are  very  complex;  for  the  purpose  of  this  on-call  manual,  the  embryology  and  pathophysiology  are  only  reviewed  as  relevant  to  the  initial  evaluation  and  treatment  of  neonatal  patients.
