Sperm function

Sperm "function" refers broadly to the collection of molecular, cellular, and physiological processes that enable mature sperm cells to move, undergo capacitation, recognize and penetrate the oocyte, and ultimately achieve fertilization. It encompasses fundamental properties such as motility, acrosome reaction, nuclear DNA delivery, and interaction with the female reproductive tract. Impairments in sperm function are a leading cause of male infertility. Research in this field investigates both the molecular mechanisms underlying normal function (e.g., through signal transduction involving cAMP, post-translational modifications of sperm proteins, ion channel regulation) and causes of dysfunction (e.g., DNA integrity defects, environmental influences, molecular deficiencies).
