The dissection of nerves and ganglia anatomically related to the pelvic organs revealed one inferior mesenteric ganglion, two testicular ganglia, two hypogastric nerves, two pelvic ganglia and two pelvic nerves. The histochemical demonstration of catecholamines by a glyoxylic acid fluorescence method revealed a rich sympathetic innervation in the ductus deferens, in the three segments of the prostate and in the convoluted ductuli efferentes. The testis, epididymis and all three pairs of bulbourethral glands presented fluorescent nerve fibers only around blood vessels. Removal of the inferior mesenteric and testicular ganglia, and hypogastric neurectomy with our without ligature and sectioning of testicular arteries, had no effect on the density of the nonvascular fluorescent fibers. Removal of the periprostatic tissue caused complete denervation of the prostate and marked denervation of the ductuli efferentes and ductus deferens. Small ganglia containing fluorescent nerve cell bodies were found close to the capsule of the prostate. The results indicate that short adrenergic neurons are responsible for the sympathetic innervation of the reproductive organs of the male opossum.
对与盆腔器官在解剖学上相关的神经和神经节进行解剖发现，有一个肠系膜下神经节、两个睾丸神经节、两条腹下神经、两个盆腔神经节和两条盆腔神经。通过乙醛酸荧光法对儿茶酚胺进行组织化学显示，在输精管、前列腺的三个部分以及迂曲的输出小管中有丰富的交感神经支配。睾丸、附睾以及所有三对尿道球腺仅在血管周围呈现荧光神经纤维。切除肠系膜下神经节和睾丸神经节，以及进行有或无结扎和切断睾丸动脉的腹下神经切除术，对非血管荧光纤维的密度没有影响。切除前列腺周围组织导致前列腺完全去神经支配，输出小管和输精管明显去神经支配。在前列腺包膜附近发现了含有荧光神经细胞体的小神经节。结果表明，短肾上腺素能神经元负责雄性负鼠生殖器官的交感神经支配。
