Figure 5. Effects of GSLS on sex hormones in the serum of D-gal-induced mice. (A) testosterone; (B) cortisol; (C) follicle-stimulating hormone (FSH); and (D) luteinizing hormone (LH). All data are represented as mean ± SEM (n = 6). *p < 0.05, **p < 0.01 compared to the NG; #p < 0.05, ##p < 0.05 compared to the MG. NG: normal group, MG: D-gal model group, GS-L: D-gal + low dosage of GSLS group, GS-H: D-gal + high dosage of GSLS group.
