Sperm motility is a major determinant of pregnancy outcome following intrauterine insemination.

PIP: Current literature dealing with sperm motility is reviewed. Laboratory observation has led to the hypothesis that the sperm tail moves when the microtubules, powered by adenosine triphosphate ATP , slide past one another, moving by means of their dynein arms, which are actual molecules of ATP activity. The clinical usefulness of determinations of various glycosidases in semen has been assessed in recent years. The neutral alpha-glycosiderase specific activity of sperm has been correlated with the percentage motility. It is postulated that an abnormal function of the epididymis may be related to decreased production of alpha-glucosidases.
