Figure 5From: Impact of TBT on the vitellogenesis and sex hormones in freshwater prawn Macrobrachium rosenbergii (De Man, 1879)(A) Section through ovary (control) showing vitellogenic oocytes (VO) with yolk globules (Yg) and encircled by a row of follicle cells (FC). (B) At 10 ng/l TBT exposure, ovary show reduction in the yolk globules (↑Yg) and disruption of the follicle cells (↑ FC). (C) Ovary showing the fusion of developing oocytes (↑ DO) and disassociation of the follicle cells (↑ FC) at 100 ng/l TBT exposure, (D) At 1000 ng/l TBT exposure, ovary showing the degradation of connective tissues (CT), loss of follicle cells (↑ FC) and abundance of immature oocytes (↑ IO). Note the reduction in the number of developing oocytes in the treated ovary compared to control (n = 3). Bar: 50 μm.Back to article page
