RESUMO
There are various causes of primary amenorrhea in phenotypically females such as, complete androgen insensitivity syndrome, pure gonadal dysgenesis, 17b-hydroxysteroid dehydrogenase deficiency, or mixed gonadal dysgenesis. Primary amenorrhea in a phenotypically female is commonly encountered in Androgen Insensitivity Syndrome. In patients with Androgen Insensitivity Syndrome, with intra-abdominal testis there is high chances of developing testicular tumour, among them Sertoli cell tumour and seminoma being the most common types.
