摘      要：This study analyzed the effects of male age and abstinence time on semen quality and explored the best abstinence time for Chinese males among different age *** parameters,including sperm kinetics,morphology,and DNA fragmentation index(DFI),were reviewed from 2952 *** were divided into six age groups(≤25 years,26–30 years,31–35 years,36–40 years,41–45 years,and45 years)and were divided into six groups according to different abstinence time(2 days,3 days,4 days,5 days,6 days,and 7 days).The differences in semen quality between the groups were compared,and the effect of age and abstinence time on semen quality was *** differences were observed in semen volume,progressive motility(PR),and DFI among the age groups(all P0.05).There were significant differences in semen volume,PR,and DFI among different abstinence time groups(all P0.05).Pearson analysis showed that male age and abstinence time were both significantly correlated with sperm kinetics and DFI(both P0.05).The box plots and histograms of men’s age,abstinence time,and semen quality show that most semen quality parameters differ significantly between the 2 days and 7 days abstinence groups and other groups at different *** for the sperm morphology parameters,sperm kinetic parameters and sperm DFI are linearly related to male age and abstinence time.
