Mechanisms of GSK3α/β regulate sperm motility and acrosome reaction. Sperm GSK3α/β is accumulated during the maturation in the epididymis. The phosphorylation of GSK3α/β led to GSK3α/β inactive, which resulted in enhancing sperm energy metabolism involved in oxidative phosphorylation and glycolysis, thus regulating sperm function. MDH, malate dehydrogenase; SDH, succinate dehydrogenase; LDH, lactate dehydrogenase; ATP, adenosine triphosphate.
