If the gonad is to become a testis, only the medullary component differentiates. If the gonad is to become an ovary, only the cortex differentiates. The length of an adult gonad depends, in part, upon the extent of gonadal-ridge differentiation.
The development of the gonads is part of the prenatal development of the reproductive system and ultimately forms the testes in males and the ovaries in females.
