(A–D) Determination of the histometric measures of the seminiferous tubules from Yangzhou ganders testicles. TD—total tubular diameter; LD—luminal tubular diameter determined by the difference between the total diameter (TD) and the sum of both measures of epithelium height (EH1 + EH2); EH—height of the seminiferous epithelium determined by mean of two diametrically opposed measures (EH1 and EH2) and the scale bar represents 20 µm at 40× magnification. (E) Diameter of the seminiferous tubules (µm). (F) Epithelium height (µm). (G) Luminal tubular diameter (µm). (H) Number of seminiferous tubules per field (under 20× magnification). Data are shown as the mean values ± standard error of the mean, *** indicates difference p < 0.001, respectively between the groups.
