Intratesticular ducts
This section demonstrates the convoluted portions of seminiferous tubules converging at the mediastinum. As they approach, these tubules lose the seminiferous epithelium and become the straight portions (tubuli recti) of the seminiferous tubules. Straight tubules, lined by modified Sertoli cells, continue into the rete testis, located within the mediastinum. 100x
