Abstract

Objective: The aim of this article was to study the ultrastructure of the boundary tissue of rabbit seminiferous tubule. Design:
Experimental study. Period: During July 2010 to July 2011. Material: Eight sexually mature male rabbits (Oryctolagus cuniculus) were used in
this study. Rabbit maturity was determined by age and semen samples. Method: Ultrastructure observations by electron microscope
transmission of normal rabbit testes. Setting: Samples processing were done in both university of Khartoum (Sudan) and then Assiut university
(Egypt). Results: The boundary tissue is formed of three lamellae, inner fibrous, inner and outer cellular lamellae. The inner fibrous lamella
consists of three strata; internal and external homogenous enclosing a middle stratum of collagenous fibers. The internal homogenous stratum
of the inner fibrous lamella is subdivided into four layers of moderate electron density. Conclusions: The general structure of the seminiferous
tubule of rabbit is similar to that of hamster and mouse, but the internal homogenous stratum is formed of four layers.
