PIP: In vivo measurements of intratubular hydrostatic pressure were taken in the testis, caput epididymis, and cauda epididymis of the guinea pig before and after vasectomy. A range of from 2 to 11 cm water pressure in these locations was observed in normal animals. A significantly greater (p less than .005) mean pressure was found in the caput epididymis than in the seminiferous tubules and the proximal cauda and in the distal cauda (p less than .0005) than in the proximal cauda. Present results and similar previous results warranted examination of the transport of sperm and fluid through the male reproductive system. The presence of a significantly greater (p less than .0001) hydrostatic pressure in the distal cauda epididymis 4 months and 1 year postvasectomy than normal is a reflection of the accumulation of sperm and fluid. However, the pressures in the caput epididymis and proximal caudal tubules were insignificantly elevated. It is concluded that changes in spermatogenesis observed after long-term vasectomy in the guinea pig are unrelated to the direct transmission of the increased caudal pressure to the testis.
