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. Key Words: reproductive hormones; spermatogenesis parameters; body weight index
According to WHO data, rapidly increasing number of individuals with excessive body weights all over the world leads to obesity pandemic [15]. Male fertility and libido reduce in some men [...]
