In the wild fauna of the Amur region there has been a decrease in the population of Siberian roe deer in recent years. Abnormalities associated with loss of reproductive quality affect the number of animals. When analyzing pathological abnormalities in the reproductive organs, it is important to take into account not only the morphology in the structure of the genitals, but also the defective development of spermatozoa. The aim of this research is to study the influence of morphological deviations in the testes and epididymides in male Siberian roe deer on the development of spermatozoa.The object of the study was 24 males of Siberian roe deer aged from 1 to 6 years old; they were divided into 2 groups of 12 individuals each, from which the testes with epididymides were selected, and visual morphometric and histological studies were performed using generally accepted methods. Morphological abnormalities in roe deer were observed at the age of up to 1 year old. The greatest number of pathologies was found in male roe deer aged from 2 to 3 years old and older than 6 years old. Histological analysis of the testes and epididymides showed violations in the composition of the structural elements of this organ; they contribute to the further development of deviations. The main reason for the violation of spermatogenesis in roe deer is oligospermia, deformation of the convoluted seminal tubules, which leads to a violation of the development of gonadocytes.
