Protein translation in sperm

...rease in sperm motility, actin polymerization, the acrosome reaction and in vitro fertilization rates. Thus, protein translation in sperm is essential for sperm functions that directly contribute to fertilization. Dr. Breitbart is confident that "The new findings would give us better understanding for treat...
