The effect of temperature on the velocity of human spermatozoa as measured by time-lapse photography.
A method of time-lapse photography for the assessment of sperm velocity is presented. The intersampling variation was not significant, nor was the effect of dilution. Sperm velocity increased with temperature within the range 25 degrees C to 40 degrees C. The possible clinical use of the technique is discussed.
