A and B The hypothalamus of the experimental thyroidectomized group treated with T4; C and D The hypothalamus of the experimental thyroidectomized group; E and F The pituitary gland of the sham-operated group; G and H The pituitary gland of the experimental thyroidectomized group; I–L The corpus luteum and the follicles of the experimental thyroidectomized group with T4 addition; (M–P) The corpus luteum and the follicles of the experimental thyroidectomized group. The scale bar in A, C, E, F, G, I, K, M, and O indicates 50 μm, whereas that in B, D, F, H, J, L, N, and P represents 10 μm
