Effect of different pH levels on sperm functional parameters. Changes in (A) intracellular ATP, (B) mitochondrial membrane potential (MMP), and (C) intracellular reactive oxygen species (ROS) levels of spermatozoa stored at different pH levels. Data represent mean ± SE. a-bP < 0.05 versus 1 d at pH 6.2
