Neurohistochemical and fine structural techniques have been employed to examine the intramural autonomic innervation of the human vas deferens following surgical division of the duct one to 15 years previously. Samples from sites on the distal (testicular) and proximal (urethral) aspects of the original vasectomy have been compared with control specimens obtained at vasectomy as to the arrangement and distribution of autonomic nerves. In contrast with tissue from the proximal part and from controls, the distal samples revealed a marked reduction in the noradrenergic innervation of the muscle coat. In addition acetylcholinesterase-containing nerves associated with the basal aspect of the epithelium were usually absent from the distal portion of the vas deferens. These findings have been considered in relation to the contractile and secretory activities of the organ following vasovasostomy and may be of importance to the maturation and fertility of spermatozoa.
运用神经组织化学和精细结构技术，对输精管在1至15年前手术切断后其壁内自主神经支配情况进行了检查。将原输精管结扎部位远端（睾丸端）和近端（尿道端）的样本，就自主神经的排列和分布与输精管结扎时获取的对照标本进行了比较。与近端组织及对照组织相比，远端样本显示肌层中去甲肾上腺素能神经支配显著减少。此外，输精管远端部分通常缺乏与上皮基部相关的含乙酰胆碱酯酶神经。这些发现已结合输精管吻合术后该器官的收缩和分泌活动进行了考量，并且可能对精子的成熟和生育能力具有重要意义。
