Resumen:
Background: Ovotesticular DSD is a rare disorder defined by the presence of both ovarian and testicular tissue in the same individual. SRY is present in approximately 1/3 of patients with 46,XX ovotesticular DSD. In SRY-negative ovotesticular DSD, the mechanism responsible for the presence of testicular tissue is not yet understood.Case Presentation: A male patient was referred to us for hypospadias and bilateral cryptorchidism at 2.5 years of age. He had a trophic phallus (32 mm x 13 mm) with coronal hypospadias and hypoplastic scrotum. Right gonad was palpable in the inguinal region; no gonad was palpable on the left side. Basal AMH (216 pmol/L) and hCG-stimulated testosterone (30 ng/dl) were low, indicating that dysgenetic testicular tissue was present. Gonadotrophins were not elevated, with FSH predominance (LH
