Fig. 1B Eﬀects of MCLR induced pathohistological damage in zebrafish testes. (A) Histopathological changes in the testes of male zebrafish after exposed to MCLR for 30 days. M: mature sperm, Sc: spermatocyte, Sg: spermatogonia; widen interstitial space (arrow), cellular vacuolation (*). The scale bars: 20 µm.（B）The ultrastructure of zebrafish testis were observed by transmission electron microscope. Swollen mitochondria (*); Vacuoles (△); autophagic vacuoles (★); nuclear heterogeneity (▲); hyperplasia of endoplasmic reticulum associated with mild expansion (arrow); Compared with the control group, the intercellular space was increased significantly (○) and the sperm morphology is obviously abnormal (#).
