Subject: There is a genetic defect that causes a male child to be born anatomically

incorrect as a female. The testicles are up inside the body and there is no 
penis. I need to know the name of this exact disorder and can it occur in one 
identical twin and not the other? They are both technically male, so by some 
kind of fluke of nature could this occur? I am writing a book and banging my 
head up against a brick wall because I don't even know what to put in the 
search engine to find this information. This disorder is the twisted ending of 
my book.
