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.
