Granulomas of the testis and excurrent ducts following vasoligation in the fowl (Gallus domesticus).
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.
