Effect of Diode Lasers on Human Sperm Motility

This preliminary study was performed to determine the effect of diode lasers on human sperm motility. The in vitro survey was performed as a randomized clinical trial, in which 25 out of 55 patients with primary or secondary infertility and asthenospermia were evaluated. It was indicated in results that the mean total sperm motility, progressive sperm motility, Class C sperm motility, Class D sperm motility, and VCL were significantly increased in samples receiving infrared and red radiation, but there was no significant difference in the control group. The findings suggest that diode lasers may be used as an optimal therapeutic option for treatment of male factor infertility resulting from disordered motility.
