ergogenic22I like to work backwards.
1) patient has normal testicles on histology, normal appearing penis
this must mean a Y chromosome is present, as testis determining factor is on the y chromosome (see above post point #2). I.e. you can eliminate choice A and B.
Theoretically, 47XY and 47XYY could also present with female genitalia due to lack of MIF, but normal 46XY is more common+12019-07-15T02:01:26Z
