Morphometric analysis of testes. a Testes index of three groups. (Testis index = Testis weight/Body weight × 100). b Histology cross-sections of seminiferous tubules. The seminiferous tubules diameters were indicated by double-headed arrows. c Average diameter of seminiferous tubules. Average number of spermatogonia cells (d) and spermatid cells (e) per section (n = 5 per group; about 30 seminiferous tubules were examined for each mouse). *P < 0.05; **P < 0.01
