sperm motility

A parameter assessed in semen analysis that consists of the ability of sperm to swim in a forward direction. Per the WHO, 60% is the lower reference limit for motility, assuming a lower limit of 20 million sperm cells per milliliter.

In mammals, physiological hypotonicity can facilitate the acrosome reaction in the sperm through calcium increase and acrosome swelling (Rossato et al., 1996; Zanetti and Mayorga, 2009); this hypotonic stress is required for the activation of sperm motility once released from the epididymis (Willoughby et al., 1996).
