title: Effect of vasoligation on the reproductive organs of immature cockerels of the domestic fowl (Gallus domesticus).
abstract: Fifteen sexually immature, 12-week-old cockerels were unilaterally vasoligated. Eight of these were killed at 4 weeks post-ligation and the remaining 7 at 10 weeks post-ligation. Granulomatous lesions in the ductus deferens were observed in 2 cockerels of the first and in 1 cockerel of the second group. Cysts showing intense granulomatous reactions were present in the epididymis in 1 cockerel of the first group and 4 cockerels of the second group. The seminiferous tubules were not seriously affected. The contralateral organs acted as controls and were grossly and histologically normal.
