Secretory function of the ductus deferens of male chickens.

Juvenile and castrate male chickens with ligated ductus deferens were treated with androgen to determine which regions of the ductus deferens were involved in fluid secretion and to determine the characteristics (pH and protein content) of the secretions. The ductus deferens developed with androgen injection contained a dilute secretion. No significant differences in pH and protein content of the fluid were observed between juvenile and castrate males. Regional ligation of the ductus deferens showed that fluid secretion occurred throughout the length of the tract.
