Gonadal dysgenesis is a rare genetically heterogeneous disorder characterized by underdeveloped ovaries with consequent, impuberism, primary amenorrhea, and hypergonadotropic hypogonadism. Mullerian agenesis or Mayer‑Rokitansky‑Kuster‑Hauser syndrome is characterized by congenital aplasia of the uterus and the upper part (2/3) of the vagina in a woman with normal development of secondary sexual characteristics and a normal 46 XX karyotype. The association of gonadal dysgenesis and Mayer-Rokitansky-Kuster-Hauser syndrome is very rare and appears to be coincidental. We report a case of a 24-years old woman who presented with primary amenorrhea. The endocrine study revealed hypergonadotrophic hypogonadism. The karyotype was normal, 46,XX. Internal genitalia could not be identified on the pelvic ultrasound and pelvic MRI. There were no other morphological malformations.
