title: [FACTORS AFFECTING SPERMATOGENESIS PRESERVATION IN RATS WITH SEMINIFEROUS TRACT OBSTRUCTION].
abstract: The aim of the study was to examine the effect of the seminal tract obstruction of different degree and duration on the morphological and functional condition of testicular tissue. The study was conducted in 50 male Wistar rats. Three experimental models of seminiferous tract obstruction were set up: obstruction of the proximal part of the ductus deferens, obstruction of the distal part of the ductus deferens and obstruction of at the epididymis level. Morphological evaluation of testicular tissue was performed at 3 and 6 months after the obstruction. It was found that obstruction at the epididymis level caused the most severe impairment of spermatogenesis.
