Comparison of methods that estimate viability of human spermatozoa by monitoring head membrane permeability revealed that wet preparations (whether using positive or negative phase-contrast microscopy) generated significantly higher percentages of nonviable cells than did air-dried eosin-nigrosin smears. Only with the latter method did the sum of motile (presumed live) and stained (presumed dead) preparations never exceed 100%, making this the method of choice for sperm viability estimates.
通过监测头部膜通透性来估计人类精子活力的方法比较显示,湿片制备法(无论使用正相或负相相差显微镜)产生的非活细胞百分比显著高于空气干燥的伊红 - 黑色素涂片。只有使用后一种方法时,活动的(推测为活的)和染色的(推测为死的)精子总数才不会超过100%,这使得它成为精子活力评估的首选方法。
