Abstract
Summary: The effect of Laser light on the motility and the velocity of human spermatozoa were measured by means of multiple exposure photography. Total sperm motility increased after Laser irradiation at 4 J/cm2, 8 J/cm2 and 32 J/cm2 respectively with respect to control. However, no influence on sperm velocity was demonstrated after Laser irradiation. This observation suggests that Laser light stimulates non-motile live spermatozoa. Zusammenfassung: Die Effekte des Laserlichts auf Spermatozoenmotilität und Spermatozoengeschwindigkeit in vitro Die Effekte des Laserlichts auf Spermatozoenmotilität und Spermatozoengeschwindigkeit wurde mittels Multiple Exposure Photography gemessen. Die GlobalmotUität der Spermatozoen steigt nach Laserbestrahlungsdosen von 4 J/cm2, 8 J/cm2 und 32 J/cm2 gegenüber entsprechenden Kontrollansätzen. Es wird kein Einfluß der Laserbestrahlung auf die Spermatozoengeschwindigkeit beobachtet. Dieser Befund zeigt, daß Laserlicht unbewegliche vitale Spermatozoen stimuliert.Keywords
