title: [Changes in morphological picture of the semen in the group of men from infertile couples in the Lower Silesia in 1977-1993].
abstract: OBJECTIVE
  To reveal the trends of the particular semen parameters changes during the 17 years period.
  
  
  METHODS
  Semen analysis results were retrospectively evaluated.
  
  
  METHODS
  We have analysed semiograms from 618 men from infertile couples in 1977-1993. Regression analysis of the results from years of observation was performed.
  
  
  CONCLUSIONS
  We showed the statistically important increase in the percentage of pathological sperms (R2 = 0.89, p < 0.0001), the slight increase in the semen volume (R2 = 0.30, p < 0.02). The total sperm count in the semen samples revealed a slight increase (R2 = 0.33, p < 0.02). The sperm concentrations and the percentage of the motile sperms remained relatively stable and relatively constant.
