Abstract:
Objective: To explore the semen quality and potential risk factors of males from the infertility clinic in south area of Zhejiang.Methods A cross-sectional study was conducted to evaluate the semen quality and risk factors in 3 01 7 males attending infertility clinic in south Zhejiang.Subjects were grouped by semen quality.The generalized linear models were used to analyze the data.Results Medians of semen parameters were 2.5 ml for volume,76 ×1 06 per ml for semen concentration,1 60 ×1 06 for total sperm count,50.0%for sperm progressive motility,62.0%for total motility,and 6.9%for normal morphology.Only 32.9% of semen samples had normal semen parameters according to WHO criteria. Abstinence duration was significantly positive associated with semen volume,concentration,and total sperm count (P<0.01 ).Single factor analysis showed that smoking,contacts of environmental pollutants,and obesity had slight detrimental effects on sperm quality.However,there were no significant differences by multiple factor analysis (P >0.05 ). Conclusion A sizable proportion of semen quality from males attending infertility clinic in south Zhejiang are low according to WHO criteria.The difference of area,life styles and environmental factors may cause the change of semen quality and that need to be further studied.
