Effect of intratesticular pressure was examined on non-motile sperms in the testis whether they move toward the epididymis when it is raised. The head portion of the epididymis of the dog was cut apart at the proximal portion to the testis fully exposing the lumen of the epididymis. The electric stimulation of perivascular nerves of the spermatic cord caused spermatozoa to flow out onto the incision site at 5 min. The number of them increased progressively, almost innumerable at 15 min. These results support the view that the elevated intratesticular pressure by electric stimulation surely works to transfer non-motile sperm in the seminiferous tubules into the epididymis.
研究了睾丸内压力对睾丸中不活动精子的影响，即当睾丸内压力升高时，这些精子是否会向附睾移动。将狗附睾头部靠近睾丸的近端部分切开，充分暴露附睾管腔。对精索血管周围神经进行电刺激，5分钟时精子流出到切口部位。其数量逐渐增加，15分钟时几乎多得数不清。这些结果支持这样一种观点，即电刺激引起的睾丸内压力升高确实有助于将生精小管中的不活动精子输送到附睾中。
