摘要
The assumed association of sperm motility with fertility has long beena preoccupation of clinicians. Whereas assessing fertility of a couple has relatively easy end-points (time to pregnancy, number of children), assessing motility does not. "[he many methods developed to determine it include assessing a sperm population subjectively (by grading) and objectively (by measuring its motion-induced movement into a light beam by spectrophotometry or nephelometry), and making measurements on individual sperm cells (by stroboscopic or multiple-exposure photography or digitized video-recordings).
