title: Successful second delivery outcome using refrozen thawed testicular sperm from an infertile male true hermaphrodite with a 46, XX/46, XY karyotype: case report.
abstract: We report a successful second delivery of a healthy infant fathered using refrozen thawed testicular sperm from an infertile male chimera. We also examined sex chromosome distribution of the seminiferous tubule. Intracytoplasmic sperm injection (ICSI) was performed using the remaining refrozen testicular sperm, which had been stored during the first treatment. Biopsied testicular cells were examined by fluorescence in situ hybridization (FISH) and the peripheral lymphocyte karyotype was tested using a G-band. Following ICSI, a second pregnancy was established, and a healthy girl was successfully delivered at 40 gestational weeks without complications. Although the husband's lymphocyte chromosomal analysis revealed a 46, XX [28]/46, XY [2] karyotype, the seminiferous tubule cells on histological examination by FISH were chimeric sex chromosome type XX [18]/XY [82]. In conclusion, this is a very rare case report of a successful subsequent delivery of a healthy infant (46, XX) from an infertile true hermaphrodite (46, XX/46, XY) using refrozen thawed testicular sperm. The seminiferous tubule cells' karyotype ratio differed from that of the lymphocytes.
