Figure 1. Sperm membrane viability and mitochondrial activity in red-rumped agoutis. (A) Representative illustration showing the parameters analyzed for sperm membrane viability and mitochondrial activity in red-rumped agouti. (B) The rate of intact or ruptured red-rumped agouti sperm membrane and mitochondrial activity labeled with H33342, propidium iodide, and MitoTracker Red fluorescent probes. (C) The percentage of sperm cells with intact membranes and normal mitochondrial activity relative to the total number of counted cells.
