Lesions of presumed congenital origin in the accessory sex glands of bulls.Aust Vet J. 1989 Mar; 66(3):80, 81-5.AV
A detailed description of lesions of presumed congenital origin involving the accessory sex glands of 11 bulls is given. All of these lesions would have been detectable by careful clinical examination during bull evaluation. Evidence presented here supports the view that congenital abnormalities such as bilateral ampulla-seminal vesicle fusion, ampulla cysts associated with luminal constriction, cysts of urogenital sinus origin, prostatic appendage, and persistent remnant of the urachus could sometimes be responsible for development of inflammatory conditions in the accessory sex glands. Anomalies such as segmental aplasia or hypoplasia of mesonephric duct derivations, or single ampulla-seminal vesicle fusion in which the ducts opened freely in the colliculus seminalis were not seen to be associated with inflammation in the accessory sex glands. The significance of these findings is considered.
