1单侧隐睾史不育患者的精子参数评价显示文摘目的:评价患者施行睾丸固定手术时的年龄对其后精子参数的可能影响。方法:47例单侧隐睾史不育患者,按照患者施行单侧睾丸固定术时的年龄分为A组(2-7岁,n=23),B组(8-13岁,n=14)和C组(14-17岁,n=10)。对3组患者的精液作精液分析和精子头-尾膜的完整性检测。结果:3组患者的精液中均可观察到活动精子,精子活动率和精子浓度有很大的个体差异,畸形精子率普遍较高,精子头-尾膜完整率低。少弱畸精子症的发生率在B组(35%)和C组(50%)升高。结论:单侧隐睾史不育患者会有较差的精子参数。单侧隐睾症患者在幼年阶段尽早治疗有利于成年后的精子发生。Petia Tzvetkova 朱伟杰 Dimitar Tzvetkov 2006生殖与避孕2006,26,5:6
