Effects of MC-LR exposure on oogenesis and spermatogenesis in zebrafish.
(A): percentages of pre-vitellogenic, vitellogenic and post-vitellogenic oocytes in ovaries from females (mean ± S.E., n = 3) exposed to MC-LR; (B): percentages of spermatogonia, spermatocytes and spermatids in testes from males (mean ± S.E., n = 3) exposed to MC-LR. Asterisk (*) and (**) indicate significant differences at P < 0.05 and P < 0.01 between MC-LR treated groups and the control group, respectively.
