No significant differences were observed in the comparison between normal sperm motility group and abnormal sperm motility group (P>0.05). 精液参数正常组顶体完整率明显高于精液参数异常组(P<0.

"These studies have also shown an increase of normally shaped sperm and a significant decrease in the percentage of morphologically abnormal sperm. 这些研究同时显示，正常型态的精子有了增加，异常型态的精子比例获致明显的降低。
