Abstract
Two hundred eighty six human semen samples with sperm counts above 200 million/ml, were divided into 3 groups according to semen volume: (1) < 1 ml (low), (2) 1 ml-5 ml (normal), and (3) ≥6 ml (high). Each group was examined for routine andrological parameters. Also examined was a possible correlation between sperm counts, semen volumes, and ages of patients. The quality of motility (percent and grade) and viability of sperm were generally lowest in specimens with a volume below 1 ml and highest in those of normal volume. Proportions of morphological normality exhibited a similar trend, lacking, however, statistical significance. The mean fructose content of low-volume semen was significantly decreased in comparison with those of normal volume. Patients with low-volume semen and sperm counts above 200 million/ml were older than those with similar sperm counts and normal volume. The mean ages of all patients with high sperm counts of semen were higher than of those with lower sperm counts. It was assumed that in contradiction to specimens with high sperm counts and low volume, those whose volumes range from 1 ml-5 ml should be considered normal with respect to motility, viability, and morphological normality.
