Sex hormones and high density lipoproteins in healthy males

The serum concentrations of testosterone, androstenedione, oestradiol and total low polar oestrogens, mainly oestradiol and oestrone, were measured in 26 healthy male subjects. The subjects were divided into two groups each of them with low (less than 1.04 mmol/l) and high (greater than 1.56 mmol/l) levels of serum HDL cholesterol. The group with high HDL cholesterol had significantly higher testosterone than the other group. Positive correlations were established between HDL cholesterol and testosterone and total cholesterol and testosterone concentration in serum.
