Changes in hormonal and metabolic status in men of an ethnic group Komi with overweight and obesity

The aim of this study was to compare hormonal, anthropometric and metabolic parameters in men of the komi ethnic group with (n=23, BMI ≥25 kg/м2) or without (n=39, 18.4≤BMI 25 kg/м2) obesity. Totally 62 males living in Komi Republic were included in the study. It has been established that obesity was accompanied by an increase in serum concentrations of cholesterol and low density lipoprotein cholesterol in comparison with control group indicating metabolic disturbance. The data shows the significant effect of BMI on testosterone and FSH serum concentration, but not on LH, estradiol, thyrotrophic hormone, thyroxin and triiodthyronin levels. Overweight and obese men had lower circulating testosterone and higher FSH level in comparison with the controls. The reproductive hormone changes in overweight and obese men can result in deleterious effects on sexual functions including erectile dysfunction, reduced libido and alteration in spermatogenesis
