Abstract

Rationale for the Study: The relevance of the study is due to a significant increase in the proportion of male fertility.

Objective of the Study: To evaluate the therapeutic efficacy of parenteral administration of a 2% solution of oxidized dextran in an in vivo model imitating impaired spermatogenesis after bacterial and viral infections, including COVID-19.

Materials and Methods: Studies performed on rats of the Wistar line. Spermatogenesis disorders were caused by intraperitoneal administration of the lipopolysaccharide Escherichia coli (LPS). In the experimental group, after 30 minutes after intraperitoneal administration of LPS, a 2% solution of oxidized dextran was administered intraperitoneally. After 3 days, the animals were euthanized with an overdose of ether anesthesia and standard histological sections of the testes were prepared, followed by a morphometric assessment of the results.

Results with Data: Parenteral administration of a 2% solution of oxidized dextran can significantly reduce all morphological manifestations of spermatogenesis disorders caused by the introduction of LPS: numerical density (Nai) of spermatozoa in the lumen of the tubule, early and late spermatids, spermatocytes, spermatogoniums, Sertoli cells, Leydig cells, as well as the numerical density (Nai) of blood vessels the peritubular zone of the testes, the volume density (Vv) of the interstitium between the convoluted seminiferous tubules and the volume density (Vv) of cell infiltration.

Conclusion: Oxidized dextran can be a very promising therapeutic and prophylactic drug for disorders of spermatogenesis caused by bacterial and viral infections, including COVID-19.
