<b>Testicular morphology in obese and sedentary Wistar rats submitted to physical training</b> - doi: 10.4025/actascihealthsci.v33i1.7698

Abstract

The aim of this study was to morphologically evaluate the effects of the cafeteria diet and physical training on the testicles of adult Wistar rats. Adult male rats were divided into groups (sedentary-control, sedentary-cafeteria, trained-control, and trained-cafeteria) In order to state the obesity condition both the Lee index and the weight of retroperitoneal and periepididymal adipose tissues were calculated. The testicular analysis involved the gonad weight and after the histological processing the Hematoxylin-Eosin staining parameters of tubular diameter, height of seminiferous epithelium, identification of the cellular sorts in the seminiferous tubules, counting of cells and overall output of spermatogenesis were done. The significant increase in the Lee index and the adipose tissue weight, in groups which received the cafeteria diet, stated the obesity condition indicating that this model is adequate to induce experimental obesity. There was no effect either from diet or training on the testicular weight, tubular diameter and height of seminiferous epithelium and also no difference in the histological organization of testicles and semineferous tubules. After cellular quantification and being calculated both mitotic and meiotic index and total capacity of Sertoli cells, it was verified a positive effect of the physical training, regardless of diet, on the overall output of spermatogenesis.
