OBJECTIVE: To investigate feasibility of using cryopreserved-thawed testicular spermatozoa from patients with nonmosaic Klinefelter's syndrome for intracytoplasmic sperm injection (ICSI).
DESIGN: Case report.
SETTING: University-based hospital and IVF clinic.
PATIENT(S): Six patients with nonmosaic Klinefelter's syndrome who underwent testicular sperm extraction for ICSI.
INTERVENTION(S): Microdissection testicular sperm extraction (TESE) and ICSI.
MAIN OUTCOME MEASURE(S): We compared results of ICSI using cryopreserved testicular spermatozoa with those previously reported in Klinefelter's syndrome and those in nonobstructive azoospermia patients using cryopreserved testicular spermatozoa at our institution with respect to embryo cleavage rate, implantation rate, and pregnancy outcome.
RESULT(S): Four of six patient couples with successful microdissection TESE achieved pregnancy using cryopreserved-thawed testicular spermatozoa. One pregnancy resulted in early-pregnancy abortion, two in delivery of healthy singleton girls, and one delivery of a healthy singleton boy.
CONCLUSION(S): Cryopreserved-thawed testicular spermatozoa can be used successfully for ICSI in patients with nonmosaic Klinefelter's syndrome.
