Figure 5From: Possible mechanism underlying the effect of Heshouwuyin, a tonifying kidney herb, on sperm quality in aging rats Fluorescence staining showing sperm mitochondrial function in each group. The sperm cells with normal mitochondrial function exhibited strong green fluorescence (red arrow), those with decreased mitochondrial function appeared to have weakened green fluorescence or sub-section phenomenon. The number of sperm cells with green fluorescence was significantly lower in the natural aging group (B), while the number of sperm cells with normal mitochondrial function was higher in the young control group (A), Shouwu pill group (D), Heshouwuyin group 1 (E) and Heshouwuyin group 2 (C), compared with the natural aging group.
