少、弱、畸形精子症患者血铅、镉浓度的测定

Effect of heavy metals on male reproduction

目的通过对男性少、弱、畸形精子症患者血铅、镉的测定,探索职业、环境、嗜好、生活习惯对男性生殖的影响。方法经检查确诊为少、弱、畸形精子症的79例患者,检测其血铅、镉含量和进行精液分析,将其结果与精液正常的34人对比,并作统计学分析。结果79例患者中,血铅(Pb)≥100μg/L或镉(Cd)≥5μg/L共53例,占总患者的67.1%;正常组中仅5例Pb>100μg/L,占14.7%,两者比较差异显著(P<0.05)。结论重金属铅、镉对精液质量影响显著。

Objective To explore effects of levels oligoasthenoteratozoospermia on male reproduction. Methords of serum plumbum and cadmium in those wih The levels of serum plumbum and cadmium, as well as sperm analysis in 79 cases with oligoasthenoteratozoospermia and 34 normal men were measured respectively, and then all data were statistically analyzed. Results Among 79 cases of oligoasthenoteratozoospermia, 54 cases had elevated level of serum plumbum or cadmium（67.1% ）, however normal group accounted for 14.7%（P〈0.05）. Conclusion The level of serum plumbum and cadmium might affect the quality of semen significantly.
