These include tumors arising from the sex cords; granulosa cells; Sertoli cells; and the specialized stroma of the genital ridge, theca, and Leydig cells. They comprise fewer than 5% of all ovarian tumors.

Although granulosa cell tumors are malignant and Sertoli-Leydig cell tumors less so, they behave in a much less malignant fashion than epithelial ovarian cancers. Benign tumors in the group include thecoma and fibroma. Granulosa cell tumors and pure Sertoli cell tumors commonly secrete estrogen, while Leydig cell tumors and combined Sertoli-Leydig tumors often secrete androgens.
