| The goal of present study was to evaluate the effects of diabetes on quantitative parameters of Leydig cells. Twelve adults Wistar rats were divided in: 1) Diabetic Group (DG), which was induced by a single intraperitoneal injection of streptozotocin (60 mg kg-1 of body weight); and 2) Control Group (CG), which received citrate buffer intraperitoneal. After eight weeks of diabetic induction, the animals were weighted, anesthetized and testicles were removed and routinely processed to paraffin embedded. Body weight (40%) and testicular weight (18%) of diabetic rats were significantly lower than control group. Diabetic rats showed an increase in interstitial compartment but the tubular compartment did not differ. The individual volume of Leydig cells and... |

| Current study investigates the effects of maternal protein restriction during pregnancy and lactation on the testis of immature rats. Female Wistar rats were mated and, after confirming pregnancy, they were divided into two groups: undernourished group (UG) fed on a diet with casein 8%, and control group (CG) fed on a diet with casein 17 %, during pregnancy and lactation. After weaning, male offspring from the two experimental groups were fed on normal diet up to 35 days old when they were euthanized. Body and testicular weights decreased in UG when compared to those in CG. Volumetric density of seminiferous tubules was higher in CG whilst intertubular space increased in UG. The number of lumenated seminiferous tubules was higher in CG than in UG. Tubular... |
