对于低渗肿胀试验分数较低的男性，即使伴有极低的精子活力百分比，卵胞浆内单精子注射也能获得正常的妊娠率。

PURPOSE
To determine if the additional burden of low percentage motility reduces the chance that sperm with low hypoosmotic swelling (HOS) test scores will achieve a pregnancy following in vitro fertilization (IVF) with intracytoplasmic sperm injections (ICSI).
METHODS
Couples undergoing IVF-embryo transfer (ET) and ICSI for low HOS tests (< 50%) were retrospectively identified. The percentage motility was divided into deciles. Pregnancy rates were determined according to the deciles of motility.
RESULTS
No differences in clinical or live delivered pregnancy rates per transfer were found in even the very lowest percent motility category.
CONCLUSIONS
The added complicating factor of low percentage motility added to sperm with low HOS test scores does not reduce the effectiveness of IVF with ICSI.
目的
确定低活动率这一额外负担是否会降低低低渗肿胀试验（HOS）评分的精子在卵胞浆内单精子注射（ICSI）体外受精（IVF）后实现妊娠的几率。
方法
回顾性确定因低HOS试验（<50%）而接受IVF-胚胎移植（ET）和ICSI的夫妇。将活动率百分比分为十分位数。根据活动率的十分位数确定妊娠率。
结果
即使在活动率百分比非常低的类别中，每次移植的临床妊娠率或活产妊娠率也没有差异。
结论
低活动率这一额外的复杂因素加在低HOS试验评分的精子上，并不会降低ICSI-IVF的有效性。
