The fascia which covers the posterior wall of the bladder also hasimportant relations with the seminal vesicles and prostate. At the upperends of the seminal vesicles this fascia splits, one layer passing in front ofthe vesicles and ampulla? of the vasa deferentia and one behind. Thatwhich passes in front, between these structures and the bladder, passesdownward until it reaches the prostate, upon the capsule of which it runsforward, separating this thin, superiorly projecting portion of the laterallobes from the bladder. Toward the median line it accompanies theejaculatory ducts within the prostate, forming the anterior part of their. Fig. 205.—Diagram of the Loge Pros- TATIQUE (Proust).

That portion of the vesical fascia whichpasses behind the seminal vesicles also continues downward, forming theposterior covering of the vesicles and vasa and being incorporated andcontinuous with the fascia of the posterior surface of the prostate (appar-ently being inseparable from the anterior leaf of Denonvilliers aponeurosis).Along the outer edge of the vesicles and along the inner edge of the vasadeferentia the two sheets of vesical fascia are united, thus forming anenveloping capsule on each side and binding these structures firmlyagainst the base of the bladder.
