Effects of Morinda officinalis Polysaccharide on Experimental Varicocele Rats

Figure 1

Changes in the left testis morphology. Three images at different magnifications are presented for each group. The normal testis morphology is shown in (a1), (a2), and (a3). (b1), (b2), and (b3) present the damaged spermatogenic epithelium caused by experimental varicocele, which is characterized by a thinner spermatogenic epithelium, less germ cells and mature sperms, atrophic seminiferous tubules, disorganized germ cells at different phases, and shedding of the immature germ cells in the adluminal compartment. In (c1), (c2), and (c3); (d1), (d2), and (d3); and (e1), (e2), and (e3), different dosages of MOP repaired the damaged structure of the spermatogenic epithelium, and the 300 mg kg⁻¹ and 400 mg kg⁻¹ doses of MOP presented a better therapeutic effect.
