Abstract
The aim of this study is determinated the ultra structural morphometric changes of the epididymis during the postnatal development of rabbits of the white population. For this, 148 rabbits aged between 4 and 28 weeks were sacrificed, epididymides are fixed for the study of microscopic parameters. The morphometric study of epididymis shows that the principal cells of 4 to 12 weeks are characterized by weak morphofunctional characters. From 14 weeks, these cells acquire morphometric characters marked by high values of hcp and zsn and low values of the report by N / hcp. This is suggestive of a physiological differentiation indicating the acquisition of cellular polarity and the development of secretory and / or absorptive character. The high N / hcp ratio of young individuals between 4 and 12 weeks of age could be an indicator of the existence of cell divisions. The structural changes of the epididymis during the postnatal development is manifested by a progressive increase of the height of principal cells and the height of the zone supranuclear. The values of hcp and zsn are higher at the level of the épididyme proximal from 16 weeks which correspond in the entered in puberty.
