Note, in the V2 group, there are tubules with depletion of germ cells (^∗). Final magnification: 200x. Percentage of normal seminiferous tubules (g), tubule diameter (h), and epithelium height (i) of animals from sham, V1, and V2 groups. Values expressed as median and interquartile range. Kruskal-Wallis analysis of variance test, followed by Dunn's test (g). Values expressed as mean ± SEM, p ≤ 0.05. ANOVA test followed by Tukey's test (h and i). Different letters indicate p ≤ 0.05.
