摘　　要：精子优选是辅助生殖技术中的重要环节。精子活力和形态等常规参数是评估精子的重要内容,近年来精子超微结构、DNA完整性、凋亡和膜成熟度等特征逐渐受到关注,针对这些特征筛选精子成为精子优选技术发展的方向。本文介绍了近年来发展起来的电泳法、电动电位法、透明质酸结合法、膜联蛋白V选择法、形态选择性单精子注射技术(IMSI)和微流控芯片法的技术原理,除微流控芯片法外其它技术均已应用于IVF或ICSI治疗中,同时对各种技术的优缺点和应用效果等方面做一综述。Sperm selection plays an important role in assisted reproductive technology. In recent years, sperm evaluation is not limited to the assessment of sperm motility and morphology, but involves more other sperm characteristics such as sperm uhrastructure, DNA integrity, apoptosis and membrane. Assessment based on these characteristics is becoming the aim of sperm selection. This article gives an overview on several newly developed techniques for sperm selection according to different technical principles, such as electrophoretic separation, zeta potential, HA binding, Annexin V binding, intracytoplasmic morphologically selected sperm injection （IMSI） and microfluidic sperm sorter, which have all been applied to IVF or ICSI with the exception of microfluidic sperm sorter. It also introduces the advantages, disadvantages and application effects of these techniques.
