Sex cord
Precursor gonadal ridge
Gives rise to testis cords, cortical cords

In animal embryology, the sex cords (or primitive sex cords) are structures that develop from the gonadal ridge. After sexual differentiation, in males the sex cords become the testis cords, which help develop and nourish the Sertoli cells, while in females they become the cortical cords.
