Abstract: Objective To explore the relationship between sperm DNA fragmentation rates and male infertil-ity.Methods Case -control study was used .Sperm DNA fragmentation rates were compared between the primary infertile males for unknown reasons (n=126) and the males whose spouses undergoing delivery in three months (n=100).Results Sperm DNA fragmentation rate of the research group was (11.95 ±4.89) %.Sperm DNA fragmenta-tion rate of the control group was (10.07 ±3.56) %.Significant difference was found between the two groups on sperm DNA fragmentation rate(t=-3.326,P=0.001).The 226 men were divided into group A with sperm DNA fragmentation rates<10%(n=130) and group B with sperm DNA fragmentation rates≥10%(n=96).The percent-age of male infertility in group A was significantly lower than that in group B (50.00%vs 61.62%) (χ2 =4.105, P=0.043).Conclusion Correlation is found between sperm DNA fragmentation rates and male infertility .
