ABSTRACT
Motility is one of the main biological properties of spermatozoa that distinguishes them from the other cells in the organism. Their ability to move is of significant importance for the assessment of the ejaculate's quality—main criterion for determination of a man's fertility. The investigation of the factors effecting the motility of the spermatozoa aims to determine the relationship between the physico-chemical characteristics of the sperm, the pathology of the male reproductive tract and the mature spermatozoid.
The results show that the highest percentage of spermatozoa with motility without progression is found in case of sexually-transmitted infections (7.25%), immotile spermatozoa are present mainly in case of specific inflammatory processes (44.5%) of the male reproductive system.
The obtained data allow determination of spermatozoa motility rating as a marker for their fertilizing ability and for evaluation of the degree of infertility. In the present study we find that the percentage of spermatozoa with the highest mobility rating in cases of vascular and congenital diseases of the male reproductive tract is 55% and 51.67% respectively
