Abstract: The aim of the study was to investigate some reproductive features – weight of testicles. diameter of seminiferous tubules and histostructure of the testes in relation with inbred level in boars. The level of inbreeding in experimental groups was Fx=0. Fx=0.25 and Fx=0. 375. The results showed that applied level of inbreeding Fx=0.25 and Fx=0. 375 lead to significant morphometric disturbances in testes as well as decreased population of germ cells in some of the tubules. We found differences in studied features between groups with different levels of inbreeding and increasing of inbred depression depending on inbreeding level.
