Correlation studies of morphological and biochemical parameters in human ejaculate in various andrological diagnoses. 3rd report. Correlations between morphological and biochemical parameters.

The result of a study of correlations between morphological and biochemical parameters in human ejaculate is presented in conclusion of an extensive study of these parameters. Basing on these results, for which a statistical significance of p less than 0.05 was calculated, it can be stated that higher fructose concentrations are associated with lower sperm density; at the same time, the higher fructose concentrations correlate with a higher percentage of non-motile and of pathologically changed spermatozoa. Similar associations can be established for certain substrates which result from fructolysis. The possibility of diffusion of enzymes from the cellular components must be considered as regards the increased activities of PGK, PGI and ATPase in seminal plasma in the presence of greater sperm density. Reliable conclusions about associations between morphological characteristics and enzyme activities can be expected in the future from appropriate measurements in the cellular elements (spermatozoa, round cells) of the ejaculate. The study results provide a further insight into the biochemistry of seminal plasma and into the associations between morphological and biochemical parameters in the ejaculate.
