摘要
本文介绍一种改进的精子上游处理技术,用以提高活动精子的回收率,并对其影响因素进行了分析。共选择精子密度正常的精子活力低下症22例进行该上游处理,活动精子回收率为50.07±23.4％。研究发现不同精子密度、精子运动速度、精液粘稠度等因素可影响活动精子回收率。作者认为该法设备操作简单,可复性强,便于在人工授精中推广应用。
A modified sperm swin-up technique for increasing the retrieval rate of motile spermatozoa is introduced and its effective factors is analyzed simutlaneously. The retrieval rate of 50.07±23.4% is obtained in 22 asthenospermic infertile with this technique. The retrieval rate may be influenced by sperm density, sperm velocity and seminal viscosity. The authors believe that this method has advantages of repitition well, simple and no special equipment is required. It is recommended to use in asthenospermia to improve the sperm motility before artificial insemination with husband semen.
