  • Title: The blood epididymal barrier to [3H]-inulin in intact and vasectomized hamsters.
    Author: Turner TT, D'Addario DA, Howards SS.
    Journal: Invest Urol; 1981 Sep; 19(2):89-91. PubMed ID: 7275558.
    Abstract:
    The net transport of [3H]-inulin into the fluids of the hamster seminiferous and caput, corpus, and cauda epididymal tubules was examined in both intact animals and those vasectomized 10 months previously. Mean isotope concentrations in reproductive tract tubule fluids did not exceeded 10 per cent of blood plasma isotope concentrations during the experiment. There were no significant differences in net transport of [3H]-inulin into any of the tubule fluids sampled. Ten months after vasectomy, the seminiferous tubule, and all regions of the epididymal tubule retain the capacity to exclude [3H]-insulin. Thus in the hamster 10 months after vasectomy, the blood testis and blood epididymal barriers to inulin are intact.
