Recent reports on the role of trace elements in human reproductive potential were summarized. Zn has been known as an important element in male sexual function, and works as key element in several seminal reactions. Se, Fe, and Cu are also essential for male fertility. Intracellular Ca play an important role in many reactions such as sperm motility, acrosome reaction, capacitation, etc. Our data on 13 elements in semen samples from 110 male patients of infertile couples were also described; 1) element concentrations were Na > P, K > Ca > Zn > Mg > Fe > Cu > Se >> Sn, Ni, Co, Cd, 2) Correlation between Se concentration and sperm concentration (r = 0.589, p < 0.001), where Se contents in spermatozoa showed very high correlation (r = 0.886), 3) Zn in semen were not correlated with sperm parameters, but were correlated with concentrations of Mg (r = 0.903), K (r = 0.810), and Ca (r = 0.715). There has been few information on the role of trace elements in female sexual function.
总结了近期关于微量元素在人类生殖潜能中作用的报告。锌一直被认为是男性性功能中的重要元素，并且在多种精液反应中起关键作用。硒、铁和铜对男性生育能力也至关重要。细胞内钙在许多反应中起重要作用，如精子运动、顶体反应、获能等。还描述了我们对110对不育夫妇中男性患者精液样本中13种元素的数据；1）元素浓度为钠＞磷，钾＞钙＞锌＞镁＞铁＞铜＞硒＞＞锡、镍、钴、镉，2）硒浓度与精子浓度之间的相关性（r = 0.589，p ＜ 0.001），其中精子中的硒含量显示出非常高的相关性（r = 0.886），3）精液中的锌与精子参数无关，但与镁（r = 0.903）、钾（r = 0.810）和钙（r = 0.715）的浓度相关。关于微量元素在女性性功能中的作用，目前几乎没有相关信息。
