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).
