Abstract
Tlae existence and the distribution of the Nymph vessels in the t?amstertestis were studied morphologically in detail. By the perfusion metlaod for fixation, theNymph vessels were observed in the interstitial tissue just adjacent to the seminiferotustubules with tire light and electron microscope.The penetrating of the Nymph vessels through the albuginea testis was confirmed andas a result of tracing these Nymph xessels, the coarse net works of the Nymph capillarieswere reconstructed and figured. The lymphatic net works were recognized to anastomoseeach other and their branches were situated just close to the seminiferous tubules and tlaeinterstitial cells. In the electronmicroscopic observation, these Nymph capillaries sltowedthe closed s)stem and so their free endings were not opened.The tissue spaces had no direct communication to the Nymph capillaries but they weresuggested to form the sinusoidal pathways of the same protein-rich liquid as that in theNymph vessels, and the important role of the interstitial tissue spaces as the passages orextracellular liquid were discussed.
