Successful birth after laser assisted immobilization of spermatozoa before intracytoplasmic injection.
OBJECTIVE
To describe the first ICSI pregnancy achieved with sperm that were immobilized by using a noncontact diode laser.


METHODS
Case report.


METHODS
Fertility center.


METHODS
A 36-year-old woman who had had primary infertility for 9 years.


METHODS
Sperm immobilization by using a 1.48-microm wavelength diode laser and subsequent ICSI.


METHODS
Fertilization and cleavage rates and pregnancy.


RESULTS
Transfer of two embryos with minor fragmentation led to a single pregnancy. The patient delivered a healthy baby in week 38 of gestation.


CONCLUSIONS
Use of a noncontact diode laser for sperm immobilization may be a useful alternative to the conventional mechanical approach.
