CST3 suppresses sperm acrosome reaction. Human sperm was capacitated as stated in the text. The sperm acrosome reaction induced by the calcium ionophore A23187 was evaluated using PNA staining. Minimum 500 sperm cells were evaluated per trial. Data are expressed as mean ± SD of five independent experiments. *p < 0.05 vs. medium supplemented with BSA and bicarbonate
