A comparative study of seminal trace elements in fertile and infertile men.
Fourteen kinds of trace elements were analyzed in the semen of 22 fertile men and 69 infertile men by means of inductively coupled plasma optical emission spectroscopy. Ca had the highest concentration, and the second and third highest concentrations were Zn and Mg, respectively. The concentrations of Ca, Cr, Mg, Pb, Sr, and Zn were almost the same between fertile and infertile men. Ni had a lower concentration in infertile than in fertile men. Many trace elements, such as Al, Cd, Cu, Mg, Mn, Mo, Sn, and Zn, had significantly higher concentrations in infertile men with normozoospermia than in fertile men. There was a significantly positive correlation between Zn and Mg levels in fertile and infertile men.
