Linear mucus penetration of spermatozoa from 75 arbitrary selected men was evaluated using a non-commercial bovine cervix mucus preparation in the same way as Penetrak, but using round glass capillary tubes instead of flat plastic tubes. The mean penetration value was 28.7 +/- 7.10 mm in 90 min and the mean sperm density 36.0 +/- 22.79 x 10(6) ml. Mucus penetration was more correlated to sperm density (r = 0.6) than to any other semen parameter. Consequently it seems to be necessary to evaluate a sliding discrimination index for adequate penetration rate depending on sperm density (regression line and confidence interval). Numerical methods for comparison of penetration rates are suggested.
使用非商业用牛宫颈黏液制剂，以与Penetrak相同的方式，对从75名任意选择的男性中获取的精子的线性黏液穿透能力进行评估，但使用圆形玻璃毛细管而非扁平塑料管。90分钟内平均穿透值为28.7 +/- 7.10毫米，平均精子密度为36.0 +/- 22.79 x 10(6)/毫升。黏液穿透与精子密度的相关性（r = 0.6）高于与任何其他精液参数的相关性。因此，似乎有必要根据精子密度评估一个用于适当穿透率的滑动判别指数（回归线和置信区间）。文中提出了用于比较穿透率的数值方法。
