== Aetiology ==
 
 
 
 
 
* Genotype XY as should be in the male.
 
* Testes develop normally and secrete Androgens and MIH
 
* Foetal genetalia are genetically insensitive to the actions of Androgens due to a point mutation in the Androgen receptor.
 
 
 
 
 
 
 
== Consequence ==
 
 
 
* Wolffian Ducts regress, allowing formation of '''female external genetalia''':
 
** Labia
 
** Clitoris
 
** Vagina
 
* Sertoli cells are present and continue to secrete MIH, causing Mullarian Duct regression.
 
* Since both Wolffian AND Mullarian Ducts regress, there is '''no internal genetalia'''.
