Effect of Mixture S on ovarian histology of PND21 offspring exposed to 0 x (DMSO), 10 x , 100x and 500x SELMA mothers’ levels. Bars represent the estimated marginal means ± SE of the number of follicles per mm2 of ovary. Significantly reduced number of preantral follicles (primary and secondary) and increased atresia were detected in all treated groups vs. DMSO. *p < 0.05; ¤p < 0.01; #p < 0.001. Number of animals used: 5–9. Representative H&E stained sections of the whole ovary are provided per group ((a) DMSO, (b) 10x, (c) 100x, (d) 500x; scale bar 200 μm). Respective framed areas are shown at higher magnification below each group. Scale bar 50 μm. Yellow arrowheads denote typical atretic follicles and asterisks indicate follicles with pyknotic cells.
