AB The  same  embryologic  anlage  produces  female  or  male  external  genitalia  depending  on  the  level  of  testosterone.  The  SRY  gene  (typically  found  on  the  Y  chromosome)  leads  to  testicular  development,  with  masculinization  of  the  reproductive  tract.  When  this  gene  is  absent,  ovaries  develop  with  subsequent  maturation  of  female  sex  organs.  The  scrotum  and  penis  are  cognates  of  the  labia  majora  and  clitoris,  respectively.  Ambiguous  genitalia  occur  when  development  and  maturation  occurs  with  a  mixed  genetic  substrate  or  hormonal  environment.
