A gonadoblastoma is a very rare type of tumor, formed by a combination of germinal cells and sex-estromous cords, which is found exclusively in patients with some gonadal dysgenesis, as is the case of Morris syndrome.
To prevent the development of this type of tumour in women with AIS who have atrophied testicles, it is advisable to remove them as soon as possible after puberty.
Atrophied testicles may be noted by palpation in the groin or lower abdomen, and may also result in inguinal hernias.
