(1) If the spermatozoa showed no motility, a new tubule closer to the testis was selected, and the process was repeated.(2) When the expelled tubules elongate, the inner epithelium is disrupted and the contents of the epithelial cell spherules are released.(3) There were bile casts present in the lumen of the proximal tubules of both kidneys.(4) The passage of sperm from the seminiferous tubules of the testis to the vas deferens takes about 12 days.(5) The tubules showed moderate-to-severe atrophy with scattered dilated tubules .
