title: Localization of frothy fluid-producing region in the cloaca of male turkey.
abstract: The region which produce a frothy fluid in the cloaca of male turkey was investigated macro- and microscopically. 2 kinds of tissues were recognized in the cloacal region: special tissue at the vicinity of the papilla of the ductus deferens (TVP) in the ventral cloaca and the triangular fold (TF), i.e., Glandula proctodealis dorsalis in the median-dorsal wall of the cloaca. TVP ejected a lymph-like fluid and TF produced a foam in the course of the mounting behavior which were added to the ductus deferens semen during natural mating.
