Low serum zinc levels are harmful to semen quality in Chinese men. In this study, eligible men aged 20-59 years old-excluding those who had ever had urinary or genital disease, tuberculosis, or occupational heavy metal contact-were examined for semen quality and serum zinc and copper concentrations. Progressive motility showed differences among the five copper groups, but multiple logistic analyses did not show that higher or lower serum copper levels had a significant effect on sperm quality. When serum zinc concentration was low, the risk of asthenozoospermia was higher. The ratio of Cu/Zn was higher in the progressive motility abnormal group than in the normal group.
低血清锌水平对中国男性的精液质量有害。在本研究中，对年龄在20至59岁之间的合格男性——不包括那些曾患泌尿系统或生殖系统疾病、结核病或有职业性重金属接触史的男性——进行了精液质量以及血清锌和铜浓度的检测。前向运动能力在五个铜分组之间存在差异，但多因素逻辑分析未显示血清铜水平的升高或降低对精子质量有显著影响。当血清锌浓度较低时，弱精子症的风险更高。前向运动能力异常组的铜/锌比值高于正常组。
