Ten adult 18-month-old male fowls were vasoligated unilaterally just anterior to the cloaca via an incision made between the base of the tail and the cloacal orifice. Two birds each were killed at two weeks and four weeks post-ligation, and the remaining six birds at 12 weeks post-ligation. Forty per cent of the birds showed severe reactions in the ipsilateral testis, epididymal region and ductus deferens. The remaining birds showed slight gross changes and near normal histology. The contralateral organs in all birds were normal both macroscopically and microscopically.
十只成年18个月大的雄性家禽通过在尾基部和泄殖腔口之间做切口，在泄殖腔前方单侧进行输精管结扎。分别在结扎后两周和四周处死两只家禽，其余六只在结扎后12周处死。40%的家禽在同侧睾丸、附睾区域和输精管出现严重反应。其余家禽表现出轻微的大体变化和接近正常的组织学特征。所有家禽的对侧器官在宏观和微观上均正常。
