The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) is a structure in the testicle connecting the convoluted region of the seminiferous tubule to the rete testis, although the tubuli recti has a different appearance distinguishing it from these two structures.
They enter the fibrous tissue of the mediastinum, and pass upward and backward, forming, in their ascent, a close net-work of anastomosing tubes which are merely channels in the fibrous stroma, lined by flattened epithelium, and having no proper walls; this constitutes the rete testis. Only Sertoli cells line the terminal ends of the seminiferous tubules (tubuli recti).

- The majority of investigations on the testis, as the main organ of male reproductive system, have been performed in mammalian species, with few studies on bird species. Thus, the structure of the ostrich testis remains largely unknown. The aim of this study was to investigate the microanatomical cha
