Drawings illustrating the seminal vesicle and the ampulla of the ductus deferens taken from two different subjects. C. The seminal vesicle and ductus deferens have been cut into to show the pitted structure of their walls. Ductus Ejaculatorius ( common ejaculatory duct).—The ejaculatory duct is a very slender canal, formed by the union of the ductus deferens with the duct of the corresponding seminal vesicle. It is less than one inch in length, and lies very close to its fellow of the opposite side as it passes through the prostate behind its median lobe. The ducts open by slit-like apertures into the first part of the urethra, one on each side of the utriculus prostaticus. They are well seen in sections through the upper part of the prostate (Fig. 1011). The mucous membrane of the duct is thrown into numerous complicated folds, and in connexion with it are a number of remarkable minute diverticula, which are enclosed within the muscular coat of the duct. Vesiculse Seminales.—The seminal vesicles are a pair of hollow sacculated structures placed in front of the rectum and behind the bladder (Fig. 1012). Each vesicle is usually about two inches in length, and has its long axis directed downwards, medially, and somewhat forwards. The superior extremity of the vesicle, which is partly covered by peritoneum, is large and rounded, and lies at a considerable distance from the median plane, behind the inferior end of the ureter. The peritoneum of the recto-vesical or recto-genital pouch separates the upper end of the seminal vesicle from the rectum; below the peritoneal cavity the vesicle.
