Morphological comparison of sperm in raw ejaculates and swim-ups showed that the swim-up process does not simply increase the proportion of 'normal' sperm. Rather, sperm of specific morphologies have characteristic grades of upward motility.
对原始射精样本和上游法处理后的精子进行形态学比较发现，上游法处理过程并非简单地增加“正常”精子的比例。相反，特定形态的精子具有特有的向上游动等级。
