Objective To describe a 46,XX male whose infertility is not accounted for by a translocation of the SRY gene to the X chromosome or to the autosomes. Design Case report. Setting Fertility Center of CHA Gangnam Medical Center, Seoul, South Korea. Patient(s) A 29-year-old male with normal male phenotype, in whom seminal analysis showed complete azoospermia. Intervention(s) Laboratory evaluations, radiologic studies, testicular biopsy, G-banding karyotype, in situ fluorescence hybridization, and polymerase chain reaction. Main Outcome Measure(s) Clinical and laboratory findings. Result(s) Peripheral blood culture for chromosome studies revealed 46,XX chromosome complement. Cytogenetic and molecular analyses excluded the presence of SRY gene. Radiologic studies displayed male structures without Müllerian ducts. Gonadal biopsy showed testicular Leydig cell hyperplasia. Conclusion(s) This is a very rare case of testicular differentiation in a 46,XX chromosomal constitution without SRY. This finding suggests that some unknown genes downstream participate in sex determination.
