Azoospermia in an 8-month-old boar due to bilateral obstruction at the testis/epididymis interface.

Abstract

An 8-month-old Yorkshire boar was presented for apparent azoospermia. Two semen collections also revealed azoospermia. Ultrasonographic examination of the gonads revealed bilateral caput epididymal dilatation and anechoic fluid within the tubules. Because a testicular biopsy revealed normal spermatogenesis, an outflow tract obstruction was suspected. Multiple sperm granulomas were found within the parenchyma of both testes at necropsy.
