ABSTRACT
Objective To analyze the semen quality in the outpatients from 3 male infertile clinics of Foshan city.Methods The semen from 1 865 outpatients with male infertility was detected and analyzed routinely by the CASA technology in strict accordance with the WHO operation technical specifications.The outpatients were divided into the normal group,mild,moderate and severe as-thenospermia groups according to the sperm vitality.Results There were 524 (28.1%)cases of abnormal sperm concentration,826 (44.3%)cases of abnormal sperm viability,985 (52.8%)cases of abnormal sperm motility,713 cases (38.2%)of teratosperm and 652 (35.0%)cases of leukocytospermia in all outpatients;the motion parameters were decreased along with the decrease of activity in each group,in which,the 6 indicators of VSL,VAP,VCL,LIN,STR and WOB were significantly lower than those in the normal activity group with statistical differences(P <0.05),furthermore,the sperm vitality had staitstcally significant differences among the mild,moderate and severe asthenospermia groups (P <0.05).Conclusion In the routine parameter indicators,the sort order of the percentage of abnormal results in turn were sperm motility、sperm viability、sperm deformity rate、semen WBC、sperm concentra-tion、semen liquefaction time、semen pH.With reduced sperm motility,the sperm motion parameters of VSL,VCL,VAP,LIN,STR and WOB were decreased,the results of each group were significantly lowered (P <0.05).
