摘要

睾丸去神经(ISN,ISN-SSN)手术2周后开始半去势实验,半去势之前和半去势之后6和24h,对大鼠进行颈静脉和睾丸静脉采血,以测定激素。结果表明,睾丸神经参与了半去势所诱导的睾酮代偿性分泌的调节过程。

Abstract

It is unclear why the concentration of testosterone increases in the testicular vein after hemicastration without corresponding alteration in gonadotropins. The present work was undertaken to examine whether the testosterone levels could be modified by denervation of the testis in adult rats. Both systemic and testicular blood samples were collected either immediately before or 6 and 24 hours after hemicastration from the rats two weeks after denervation of either inferior spermatic nerves (ISN) or ISN plus superior spermatic nerves (ISN-SSN).
