Mutations in SOX9 in an XY fetus can result in phenotype ranging from normal male to normal female with dysgenic gonads.
The labia majora are fatty folds covered by hair-baring skin that fuses anteriorly with the mons verenis, or anterior prominence of the symphysis pubis, and posteriorly with the perennial body or posterior commissure.
