Fig. 2 Histomorphometric analysis of testes following exposure to BPS. (A) Proportion of surface area occupied by spermatogenic cysts after 14 days of exposure to DMSO (Vehicle, control) or BPS (0.5 µg/L). Cysts include undifferentiated type A spermatogonia (Aund), type A differentiated spermatogonia (Adiff), type B spermatogonia (SpgB), primary spermatocytes (Spc), and spermatids (Spt). Data are presented as fold change relative to the control group. (B) Number of sperm per field obtained using IMAGEJ Software. Results are expressed as mean ± standard error of the mean (SEM) (n = 6). (*) indicates a significant difference observed between the different groups with p < 0.05; (NS) indicates no significant difference.
