[Seasonal changes in results of semen analysis from male members of an infertile married couple].

Analysis of 200 semen samples of men from childless couples was performed in order to evaluate the sperm characteristics during the year. Estimated were following features: semen volume, sperm density, motility and percentage of pathological forms. The sperm estimation data obtained from 4 seasons of the year was statistically evaluated. Statistically significant changes were found only in the percentage of pathological sperm forms. During the spring period the observed values were significantly higher than during summer and winter. From the correlation tables it appears that together with the increase of sperm density the percentage of pathological forms decreases. Whereas increase in density is correlated with the increase of sperm motility. It was also revealed that together with the increase of the percentage of pathological forms the motility decreases. Analogical results were obtained in all seasons of the year which indicates that there is a clear regularity existing. The least apparent dependencies were found in winter period.
