摘　　要：用火焰原子吸收光谱法测定了输精管注射“504”粘堵术和经输精管向附睾注射鱼肝油酸钠术的63例对象精浆中锌、铜、镁、钙、钾五种元素含量。两种节育术后精浆中均出现钙的显著降低和铜的显著增高;相关分析提示,粘堵组出现铜和钙的平衡失调,鱼肝油组发现铜和镁失衡。作者认为,经输精管向附睾注射鱼肝油酸钠后,附睾小管可能存在不同程度的梗阻,而在管腔复通的对象,其附睾内元素代谢亦发生了紊乱,表明附睾功能受到损害。本文结果显示附睾是男子生殖道元素代谢的重要器官,是精浆钙的重要来源。The concentrations of zinc (Zn), copper (Cu), calcium (Ca), magnesium (Mg) and potassium (K) ions were determined in 63 men after they had accepted two kinds of ster- ilization i. e. occlusion sterilization of vas deferens and injection of sodium morrhuate (SM) via vas deferens into epididymis. The results show that the content of Ca^(2+) in seminal plasma was significantly increased and that of Cu^(2+) was significantly decreased. By correlation analysis, a relationship of imbalance between Ca^(2+) and Cu^(2+) in the occlusion group and between Ca^(2+) and Mg^(2+) in the SM group was found respectively. It was speculated that Ca^(2+) in seminal plasma mostly came from epididymal fluid, but Cu^(2+) was neither from epididymis nor from spermatozoa. The results suggest that there were varying degrees of occlusion in vas epididymides after injection of SM, and that even with those whose vas epididymides were recanalized, the functions of secretion and/ or absorption of the epididymis were more or less damaged. The results further show that the epididymis is critical for the inorganic element metabolism in the male genital tract, and also an important origin of seminal plasma Ca^(++).
