ABSTRACT
OBJECTIVES: To evaluate the relation among the concentration of selected air pollution and seminal parameters, examined from 1977 to 2000. DESIGN: Semen analysis and air pollution results were retrospectively evaluated. MATERIALS AND 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. RESULTS AND 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.

OBJECTIVES: To reveal the trends of the particular semen parameters changes during the 17 years period. DESIGN: Semen analysis results were retrospectively evaluated. MATERIALS AND 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. RESULTS AND 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.

The authors present a rarely-observed case of endolymphatic stromal miosis (ESM) in a fifty-year old female patient. ESM is a low malignancy stromal endometrial tumor that is usually treated by surgery.
