Fig. 2. oxLDL level is significantly elevated in the serum and testes of HFD mice.

Fig. 2

Serum triglyceride (a), serum total cholesterol (b), serum LDL (c), and serum HDL (d) levels in mice were detected by a biochemical analyzer. Serum oxLDL (e) and testicular oxLDL (f) levels were measured by ELISA. *P < 0.05, **P <0.01, compared with SD-fed mice. (g) Immunohistochemical staining indicated that oxLDL accumulated in the testicles in SD- and HFD-fed mice, and the arrows show sites of positive expression (n = 8 per group; scale bar, 20 μm). Transmission electron microscopy showing the ultrastructural characteristics of mitochondria of Leydig cells in SD- and HFD-fed mice. The arrows show the absence of mitochondrial cristae (n = 8 per group; scale bar, 0.5 μm).
