[A simple microphotographic method for the evaluation of sperm motility].

A simple objective method for examination of sperm quality, both for practical and research purposes, is described. The results obtained show that the evaluation of samples must be performed by 15 minutes after the removal of the spermatozoa from the culture system and by 5 minutes after the placement on the microscope slide, in order to avoid the influence of external conditions on sperm motility. From the comparison of parameters examined (percentage of sperm motility, mean velocity, lateral head displacement, number of waves per second, distribution in individual speed intervals) it follows that media used for sperm incubation (B2 and F 10) do not affect negatively sperm motility and may be exchanged with each other if necessary. The results contribute to the improvement of diagnostic and treatment of andrological disturbances. The study will be used in our programme of treatment of infertile couples.
