The prostatic vesicle has the shape of an inverted J in lateral view and its distal portion penetrates the anterior region of the welldeveloped penis bulb. The prostatic vesicle is lined with ciliated, cuboidal epithelium. This epithelium is crossed by gland cells producing erythrophil granules and is surrounded by a circular muscle (10 µm thick). The ejaculatory duct is horizontal and slightly sinuous and opens at the tip of the penis papilla. The ejaculatory duct is lined with ciliated, cuboidal epithelium and is surrounded by a 3 µm thick circular muscle.
