Hyperosmolality in Intraluminal Fluids from Hamster Testis and Epididymis: A Micropuncture Study

Abstract
Intraluminal fluids from hamster seminiferous tubules, rete testis, and caput, corpus and cauda epididymidis were obtained in vivo by micropuncture. Rete testis fluid is isosmolar with serum. Fluids from the seminiferous tubules and all sites in the epididymis are hyperosmolar.
