Intratesticular ducts

A section of fetal testis demonstrates the convoluted portions of seminiferous tubules converging at the mediastinum. As they approach, these tubules lose their germ cells and become the straight portions (tubuli recti) of the seminiferous tubules. Straight tubules, lined by Sertoli cells, continue into the rete testis, located within the mediastinum. 40x
