Nodulii limfoizi perivasculari ai complexului funiculotesticular ca componeţi ai patului hemolimfomicrocirculator

Abstract

Abstract Background: The male sterility represents a medical and social problem. According to the American Associations of Reproductive Medicine 50-60% of sterility represents the male one. The human spermatogenesis follows during all period of male life. An important role in the regulation of spermatogenesis is considered to belong to lymphocytes, which accumulate around the seminiferous canals. The goal of corresponding work represents the research of morphological peculiarities of the perivascular lymph nodes in correlations with microcirculation of the blood and lymph flow. Materials and methods: The evaluation of these structures was able to put in evidence the total anatomical piece by marco-microscopical method using as dye, the reactive Schiff. Results: In premiere, along of the spermatic cord was establish a lot of lymph nodules. Majority of found nodules was localized along of the blood and lymph vessels, these groups of nodules are located in the region of the bifurcation of the blood vessels, among the loops of the pampiniform plexus. A specific group is the lymph nodes, located between the loops of the pampiniform plexus and on the path of the main lymphatic vessels, which can be organized as solitary or aggregated. Conclusions: So, all the perivascular lymph nodes together with the other types of nodules represent a unique immune system that is the first barrier that performs the immune control of the blood circulating to and from the testicle.
