[Content of testosterone and of different classes of lipoproteins in the blood plasma of men 40-59 years old].

The blood plasma of males aged from 40 to 59 (227 practically healthy individual and 48 persons suffering from ischemic heart disease) was tested for the content of testosterone, cholesterol, triglycerides, cholesterol of various classes of lipoproteins and the lipoprotein spectrum by electrophoresis in polyacrylamide gel. It was found that a change in the testosterone level in the blood plasma, even within the limits of physiological values, may affect the plasma lipoprotein spectrum: a decrease in the testosterone concentration is attended with an increase in the content of atherogenic (beta- and pre-beta-) pipoproteins and a decrease in the content of alpha-lipoproteins.
