Transsection of the hypogastric nerves and/or pelvic nerves was performed on 18 adult male dogs. Prostates were removed on the 7th, 14th and 21st postoperative day to examine histologically. The denervation caused severe structural changes on the dogs prostate, which could be summarized as follows. 1.Atrophy of the epithelium as well as myxomatous degeneration resulting in proliferation of collagenous fibers in the stroma was the most prominent finding commonly seen in the various denervating groups. Since cystic dilations of the prostatic gland or capillaries were indefinitely observed in some cases, these findings could not be confirmed as typical changes caused by the denervation. 2.The degenerative changes were recognized on the 7th day and more conspicuous on the 14th day after denervations. On the 21st postoperative day, however, the degeneration of prostatic tissue became considerably slight.
