Experimental groups and effect of age and exercise training on rats’ testicular morphology. (a) Experimental groups. (b) Representative H&E stains of histological morphology of rat testes of the four experimental groups (upper panels, ×100 amplification; lower panels, ×400 amplification). (c,d) Box and whisker plots show the (c) area of seminiferous tubules and (d) basal lamina thickness of the four experimental groups. The horizontal line displays the median, the box edges show the 25th and 75th percentiles and the whiskers show the smallest and highest value within 1.5 box lengths from the box. (n = 8 for 35 W Sedentary; n = 9 for 35 W Exercised, 61 W Sedentary and 61 W Exercised). * p < 0.05; ** p < 0.01. a—Significantly different from 35 W Sedentary; b—significantly different from 61 W Sedentary.
