Abstract
In the past few decades, there has been a decline in male fertility worldwide. The article is devoted to the study of the reproductive health of subfertile men. Purpose of the work: analysis of the biochemical composition of sperm plasma, spermogram and sperm morphology in subfertile men of reproductive age. The study included 85 patients aged 25 to 45 years, who were under observation in the clinic of Professor M.A. Florova (Samara): 60 patients seeking help to optimize reproductive health and procreation planning (a group of subfertile men, spermogram indices have deviations) and 25 clinically healthy men - a comparison group (control, spermogram indices are within the WHO norm). In subfertile men, morphological abnormalities of spermatozoa and changes in the biochemical composition of sperm plasma (increased concentration of transamination enzymes) were established. Spermatozoa with immature chromatin were identified. Electron microscopic analysis revealed fragmentation of sperm DNA: the highest percentage of spermatozoa with fragmented DNA was found in subfertile men (more than 22%).
