The purpose of the study was to examine male reproductive organs of the Polbar breed of chickens with regard to age and with particular emphasis on morphometric values. In addition, an analysis was undertaken to check if this unique polbar breed of chickens had specific characteristics of the reproductive tract, distinct from those presented in specialist literature. Testicles and vas deferens were extracted from 10 males in 6 age groups (one day old and 8, 12, 18, 24, 33 and 64 week old) as material for analysis. A right testicle with epididymis and part of the semen duct (its middle section) were taken for histological examination. The weight of testicles as well as their percentage in the overall body weight grows along with age and increase in body weight. The length of vas deferens grew in relation to age and body weight until the 18th week of life, after which a reduction in length took place. No specific characteristics for the Polbar breed were observed in the microscopic analysis of their reproductive organs.
