Heavy metals content in the indicatory biosubstrates of fertile and infertile men of urbanized territories.

Abstract

The article presents the results of studying features of heavy metals content - lead, cadmium, copper and zinc in the whole blood and ejaculate of fertile and infertile men. The concentration of metals in biosubstrates was determined by inverse voltamperometry method with the usage of АVА- 2. It is revealed, that maintenance of lead and cadmium practically in all biosubstrates of fertile men is 1,3-2,2 times higher as compared to the indices of infertile patients and in all investigated groups it exceeds normative levels by 1,2-6,4 times. Thus, sterile men have the expressed disbalance of copper in the organism, maintenance of which in the blood is 1,7-2,3 times higher against the analogous indices of fertile group and physiological level. Concentration of zinc in ejaculate of men with normal fertility is 9,3 times higher as compared to analogous indices of sterile men and by 30,9 times exceeds its level in blood of fertile group, this testifies to the exceptionally important role of zinc for the generative sphere of men. In biosubstrates of fertile men, living in conditions of technogenically polluted territories, concentration of zinc is by 1,2-1,5 times lower than physiological levels, this may testify to probability of forming zinc-deficient states in this contingent of population.
