The micrograph of gonad histology of the patient (hematoxylin and eosin staining). A Epididymal structure showing the epididymal duct surrounded by pseudostratified columnar epithelium. The cavity surface is flat, and circular smooth muscle fibers are observed outside of the epithelium (Magnification: 100 ×). B&C Spermatogenic tubules and interstitial cells can be seen in testicular tissue. There are only Sertoli cells in seminiferous tubules rather than definite spermatogenic cells. Small clusters of interstitial cells were observed among seminiferous tubules (the areas are outlined by the red lines in Fig. C). (Magnification: B, 100 × ; C, 200 ×)
