The aim of this study was to investigate the effect CS2 of on human sperm chromosomal aberration.The human sperm/hamster egg fusion techniquse was used to analyze 203 human sperm chromosome complement form 9 healthy volunteers.The incidence of numerical aberration was 1.0%,and that of structural chromosome aberration was 5.9% and total abnormalities was 6.9%.Structural aberrations consisted of breaks,deletions, centric rings,fragments,and chromatid exchange.The results from high concentration group(10μmol·L-1 CS2)showed that the incidence of chromosomal aberration rate was significantly higher than that of the control group.The results indicate that high concentration of CS2 might directly cause mutatenesis f the germ cell.
