OBJECTIVE: To describe the first ICSI pregnancy achieved with sperm that were immobilized by using a noncontact diode laser.DESIGN: Case report.SETTING: Fertility center.PATIENT(S): A 36-year-old woman who had had primary infertility for 9 years.INTERVENTION(S): Sperm immobilization by using a 1.48-microm wavelength diode laser and subsequent ICSI.MAIN OUTCOME MEASURE(S): Fertilization and cleavage rates and pregnancy.RESULT(S): Transfer of two embryos with minor fragmentation led to a single pregnancy. The patient delivered a healthy baby in week 38 of gestation.CONCLUSION(S): Use of a noncontact diode laser for sperm immobilization may be a useful alternative to the conventional mechanical approach.
