为了提供简便,精确的精子功能实验,进行了精子低渗膨胀实验(HOST)与其它精子功能实验对比性研究。 作者以105名主诉不育的男性患者作为研究对象。平均年龄32.1岁,排除其它所致不育因素;病史、物理检查及激素测定均正常。手淫法取精液样本,室温下液化。一小时后测精液容积、精子密度、精子活率和精子活力。按Jeyendran等报告方法进行精子膨胀实验,等量果糖溶液(150mosm)和枸橼酸钠溶液(150mosm),离子强度0.15U
In order to provide a simple and accurate sperm function experiment, a comparative study of sperm hypotonic expansion experiment (HOST) and other sperm function experiments was conducted. The author of 105 male patients complained of infertility as a research object. The average age of 32.1 years, excluding other causes of infertility factors; history, physical examination and hormone determination were normal. Masturbation method to take semen samples, liquefied at room temperature. Sperm volume, sperm concentration, sperm motility and sperm motility were measured after one hour. According to the method reported by Jeyendran sperm expansion test, the same amount of fructose solution (150mosm) and sodium citrate solution (150mosm), ionic strength of 0.15U
