title: Effects of overweight and obesity on the spermogram values and levels of reproductive hormones in the male population of the European north of Russia.
abstract: The effects of excessive body weight and obesity on the reproductive potential of the male population of the Russian European North (Arkhangelsk), characterized by a specific northern adaptive metabolic type were studied. Spermogram values and levels of reproductive hormones were compared in men with normal and excessive body weights and with obesity, using body weight index and waist circumference as indicators of abdominal visceral obesity. Irrespective of the indicator used, the total count of spermatozoa and their concentration in the ejaculate were significantly lower in men with obesity than in overweight men. Serum testosterone concentration was lower in obese men in comparison with men with normal body weights. Higher spermatogenesis, but not testosterone values, were observed in men with excessive body weight vs. men with normal body weights or obesity, which was presumably a characteristic feature of the northern metabolic type.
