Obesity should be considered as a separate risk factor that contributes to the development of male infertility. Aim. To assess obesity impact level on semen disturbances. Methods. The study included 130 males with fertility disorders, who, depending on the level of body mass index (BMI), were divided into two groups. The first group included 67 men with a BMI of 22,7±2,9 kg/m². The second group included 63 men with 38,6±4,3 kg/m² (p <0.05). Results. The significant tendency to decrease in the levels of LH, FSH, testosterone and an increase in the level of estradiol in men with an increase in BMI compared to men with normal weight was established (p<0.05). In addition, obese men sperm motility was 8.2% worse (p<0.05). Conclusion. In men with obesity and fertility disorders, the concentration and number of motile forms of spermatozoa are significantly lower compared to men with a normal body mass index.
