Abstract:
Objective To investigate the relationship between high DNA stainability(HDS)and routine semen parameters.Methods Semen samples were collected from 396 men of childbearing age who were admitted to our department.Correlations of HDS with routine semen parameters and age were analyzed.Multiple linear regression analysis was performed to identify the routine semen parameters that had the greatest influence on HDS.The correlation of HDS and DNA fragmentation index(DFI)with routine semen parameters and age in 244 patients with teratozoospermia was analyzed.The 244 patients were divided into extremely severe,severe,moderate,and mild teratozoospermia groups,and differences in HDS,DFI,and routine semen parameters were compared among the four groups.Results HDS was negatively correlated with total sperm count,sperm concentration,sperm progressive motility,and normal sperm morphology rate(NSMR)(P<0.01).After adjusting for potential confounders,including total sperm count,sperm concentration,sperm progressive motility,NSMR,and DFI,NSMR had the most significant negative effect on HDS(P<0.05).In the 244 patients with teratozoospermia,HDS was negatively correlated with NSMR(P<0.01)and positively correlated with the percentage of sperm head and tail abnormalities(P<0.05),while DFI was positively correlated with the percentage of sperm tail abnormalities(P<0.01).There was a significant difference in the percentage of sperm head abnormalities among the four teratozoospermia groups.The more severe the malfor-mation,the higher the percentage of sperm head abnormalities was(P<0.001).HDS in the extremely severe teratozoospermia group was significantly higher than that in the mild and moderate teratozoospermia groups(P<0.05).No significant differences in DFI were found among the four groups(P>0.05).Conclusion HDS was closely correlated with routine semen parameters and was a crucial biomarker for assessing sperm quality,particularly the extent of sperm head abnormalities.
