Materials and methods:

In order to update concepts related to DSD with 46,XX karyotype without numeric or structural abnormalities, a search of information was carried out for the last 10 years in which three subcategories are described: Disorders of gonadal (ovarian) development, Disorders related to androgenic excess and other abnormalities (vaginal atresia, cloacal exstrophy, uterine abnormalities and labial adhesions).

Conclusion:

The great variability of phenotypical manifestations in this kind of DSD may create confusion in diagnostic approaches guided by clinical findings. This presentation variability, paired with a lack of knowledge of the pathophysiology, can contribute to delayed or non-conclusive diagnoses. For these reasons, deepening the knowledge of the causes and clinical manifestations of this class of clinical conditions will result in the well-being of the patient and his family.
