目的 旨在通过对比正常形态精子和典型畸形精子的拉曼峰谱,深入了解精子有机成分的组成,并借助拉曼光谱建立一种非侵入性精子形态的分析检测方法.方法 以6例捐精者正常形态精子为实验组(其中包括一例已被证实使女性受孕),以3例典型畸形的精子样本为对照组,其中一例为圆头精子症,精子形态学分析显示为100%圆头精子;第二例为严重畸形精子症,精子头自颈部与尾部分离,形态学分析显示98%的精子形态出现异常,第三例为原发性不育(不育年限达12年)精子标本,精子标本被IVF中心确诊为完全受精失败.根据传统精子形态分析方法,按精子的顶体、颈部、尾部大小划分5个扫描区域,每条精子共要扫描23个点,从9份精子样本中,每例选取了5条精子,每条精子经2名技术员重复检测,共做了45条精子共90次的拉曼光谱分析.

背景 非梗阻性无精子症(Non-obstructive azoospermia,NOA)占男性不育的10%,占无精子症患者的60%.唯支持细胞综合征(Sertoli cell-only syndrome,SCOS)是NOA中最严重的一种病理类型.目前NOA的发病机制还不清楚,支持细胞(Sertoli cell)是精子发生过程中最重要的体细胞,为精子发生提供了重要的微环境(niche).本研究旨在探
