Abstract
BACKGROUND: Hypospadias is one of the most prevalent urogenital malformations in clinic. However, some hypospadias may have a more complex disorder of sex development. Usually, hypospadias in these patients is severe. Among them, the 46,XX male sex reversal syndrome is a rare disorder of sex development, and this may be the main reason for this type of hypospadias being difficult to repair. CASE PRESENTATION: We present a Han nationality 19-year-old male with failure of repeated repair of hypospadias. No sperm was found on semen analysis. Lingual mucosal graft was carried out for this patient. It still did not succeed after using lingual mucosal graft repair. Karyotype analysis of this patient confirmed 46,XX karyotype. CONCLUSION: Hypospadias with 46,XX male sex reversal syndrome is hard to repair. Chromosome karyotype examination in patients with hypospadias is suggested. Genetic testing is recommended. In the future, further research is needed on the pathogenesis of disease and how to treat and prevent it.
