Many details concerning the innervation of the genital organs remain as yet unknown, especially of the testis, epididymis, ductus deferences, prostate and penis, which participate in spermatogenesis, ejaculation and erection. Scarcely any histochemical studies have been carried out on the peripheral distribution of their nervous supply. The localization of adrenergic and cholinergic nerves in the genital organs was clarified by light microscopy and comparative studies on the innervation of these structures between dog and man were conducted. The following results were obtained. The study of distribution of catecholamine (CA) fluorescent nerve fibers and acetylcholinesterase (AChE) positive nerve fibers within normal genital organs revealed a relatively abundant distribution of CA fluorescent fibers and AChE positive fibers in the testis in both dog and man. These fibers were noted both in the interstitial tissue and in the vascular wall of the interstitial tissue. In the epididymis, CA fluorescent fibers and AChE positive fibers were noted rather abundantly in the muscular layer and interstitial tisue. No difference was noted according to their locations such as the head, body and tail.
