Morphological features of drainage systems of the testicle
Abstract
Objective. To determine the peculiarities of organization of morphological structures of the drainage systems of a testicle and their role in pathogenesis of infertility in the men.
Маterials and methods. The structure and interrelationship of morphological parameters of the drainage systems of a testicle were investigated in 71 biopsies of a testicle, excised during necropexy in men of the adult age (22 - 35 yrs old). On histological preparations of testicles, using morphometric rule АМ-9-4 and the Stefanov’s net on 25 points, there were measured the external diameters of the arteriolas, capillaries, venulas and the nerves.
Results. During tоtal investigation of histological sections of the ductus deferens preparations in part of a deep ring of inguinal channel there were obtained following morphological data: the Abstract quantity of big vessels in all the sections of preparations consisted of 16 аrteries with a general square 51.3805 × 10-3 mm2; 28 veins with general square 38.2511 × 10-3 mm²; 18 аrteiols with general square 2.8136 × 10-3 mm²; 30 venulas with general square 2.2681 × 10-3 mm²; there were revealed as well 4 nerves of general square 0.3686 × 10-3 mm² and 4 neural trunks of general square 3.5801 × 10-3mm².
Conclusion. The data obtained, concerning histological and morphological investigation of samples of ductus deferens confirms probability, that in its proximal part the blood-bearing vessels are present, which are bigger but lesser in number, while the nerves, diameter of which is objectively lesser than in the nerves trunks, are more pronounced in direction of distal part of ductus deferens.
