Summary

Disorders of sex development (DSD) include congenital conditions where developments of chromosomal, gonadal or anatomical sex are atypical. Ostrer in 2000, reported a prevalence of 1:20 000 for 46 XY DSD and complete gonadal dysgenesis. A 21-year-old patient consulted for sexual ambiguity at the out-patient department of the Philippine general hospital. At birth, the perceived female external genitalia and clitoromegaly, led the parents to register and eventually rear the patient as a female. At puberty, he developed masculine features and growth of phallus. Patient was more interested in male activities and began to identify himself as male in the community. The discrepancy between his birth certificate and his male gender jeopardised his ambition to become a policeman; this led him to seek medical consult. On physical examination, he was phenotypically male. The external genitalia showed the phallus length of 3.5 cm and perineoscrotal hypospadias. Chromosomal sex was normal 46 XY with neither numerical nor structural aberrations in all cell lines, serum testosterone was low and gonadotrophins were elevated. Whole abdominal CT scan showed bilaterally undescended testes and a 4.5 cm blind vaginal pouch seen on genitogram. Bilateral orchidectomy with first stage repair of hypospadias was performed. On histopathology, the right testis was fibrotic and the left testis showed minimal testicular tissue with absent spermatids. The clinical, endocrine, cytogenetic and histopathologic data are consistent with gonadal dysgenesis syndrome.
