RÉSUMÉ
Objective To investigate the relationship between semen trace elements and sperm density and motility in male infer‐tile patients .Methods A total of 116 cases of male infertility patients recruited in this hospital from September 2013 to September 2014 were collected and divided into the sperm density anomaly group (59 cases)and sperm motility anomaly group(57 cases) .Other 56 cases of fertile healthy men were enrolled into the control group .Sperm density and motility were analyzed and levels of calcium , phosphorus ,magnesium ,copper ,icon and zinc were detected in seminal plasma .Results Seminal level of calcium ,phosphorus ,zinc and iron in sperm density anomaly group were significantly lower than those in the control group ,while the level of copper was higher than that in the control group ,had statistically significant differences (P<0 .05) .Seminal level of copper in sperm motility a‐nomaly group was higher than that in the control group ,while levels of zinc and iron were lower than those in the control group ,had statistically significant differences (P< 0 .05) .Conclusion Sperm motility and density are significantly correlated with trace ele‐ments levels in seminal plasma .Routine determination of trace elements in seminal plasma in infertile men should be recommended , which could be helpful in fertility assessment and treatment .
