Abstract

Individual human sperm can be micromanipulated in three dimensions using a 1.06 μm Nd:YAG laser trap. Single sperm swimming with velocities in the range of 65 to 85 μm/sec can be trapped with 40 mW of power through 120 seconds without a deleterious effect on velocity. Even though it will be necessary to further evaluate the effects of laser light on specific functions of sperm, our data suggest that decreasing the time of manipulation to a minimum will increase the safety of the micromanipulation procedures. Laser traps may play a role in assisted reproductive technology by facilitating the selective transport of individual sperm.
