The structure of pathozoospermia in young men with post-pubertal visceral obesity and a non-aggravated andrologic anamnesis

Introduction. Given the frequent development of visceral obesity in men, it is important to study its effect on spermatogenesis.

Aim. Assessment of the structure of pathozoospermia in young men with post-pubertal visceral obesity and a non-aggravated andrologic anamnesis.

Materials and Methods. In a single, one-stage study, 80 men with post-pubertal alimentary visceral obesity aged up to 30 years were included. The length of the circumference of the waist, the level of gonadotropins and total testosterone, the antioxidant activity of the ejaculate, its electron microscopic examination were estimated. Statistically significant differences were considered between groups at p <0.05.

Results. 24% of men did not have pathosoospermia. The main pathogenetic phenomenon, revealed in patients with pathozoospermia, was astenozoospermia - 100%. There was also a high prevalence of teratozoospermia - 36%. The prevalence of oligozoospermia was 11% of cases. An increase in the content of spermatozoa with insufficiently condensed chromatin and a decrease in the antioxidant activity of the ejaculate were characteristic of all types of pathozoospermia in obese men. A decrease in testosterone levels was characteristic of oligozoospermia. At the same time, statistically significant negative correlations between waist circumference and testosterone level, quantitative indicators of ejaculate, its antioxidant activity, as well as a positive correlation between the waist circumference and the content of spermatozoa with insufficiently condensed chromatin were established.

Conclusions. In young men with post-pubertal visceral obesity and a non-aggravated andrologic anamnesis, the prevalence of pathozoospermia in our study was 76%. The most common was oligozoospermia, which was characterized by the presence of the syndrome of normogonadotropic hypogonadism, which developed in patients with the most pronounced visceral obesity. An increase in the content of spermatozoa with insufficiently condensed chromatin and a decrease in the antioxidant activity of the ejaculate is characteristic of all types of pathozoospermia in obese men, which is due to oxidative stress.
