title: [Semen analysis results and air pollution in the group of men from infertile couples in the Lower Silesia in 1977-2000].
abstract: OBJECTIVE
  To evaluate the relation among the concentration of selected air pollution and seminal parameters, examined from 1977 to 2000.
  
  
  METHODS
  Semen analysis and air pollution results were retrospectively evaluated.
  
  
  METHODS
  We have analysed semiograms from 1363 men from infertile couples inhabiting Lower Silesia. Seminal volume, sperm concentration, percentage of pathologic sperms were measured in all men. Estimation of mean seminal volume, total sperm number, sperm motility, and percentage of pathologic sperms per year was performed. Average values for NO2, CO, SO2 and dust concentrations during the study were taken from official sources.
  
  
  CONCLUSIONS
  We showed the statistically significant increase in the percentage of pathological sperms (R2 = 0.9, p < 0.05), the slight increase in the semen volume(R2 = 0.4, p < 0.05). The total sperm count in the semen samples revealed a slight increase (R2 = 0.25, p < 0.05). The sperm concentrations and the percentage of motile sperms remained relatively stable and relatively constant. Statistically important decrease in NO2 (R2 = 0.85, p < 0.05), SO2 (R2 = 0.96, p < 0.05) and dust concentration (R2 = 0.89, p < 0.05) and no change in CO concentration was revealed. There is no correlation among concentrations of dust, NO2, SO2, CO and the increase in percentage of pathologic sperms.
