Semen from 5210 sperm bank donors was analyzed and trends in semen quality were evaluated at Shandong Human Sperm Bank between 2008 and 2014. After 2-7 days of abstinence, semen samples were collected. Measurements of semen volume, sperm concentration, sperm forward motility, and total sperm count were performed. There were significant declining trends in semen volume, sperm concentration, sperm forward motility, and total sperm count. Our results indicate that the quality of semen in this cohort of sperm donors had decreased during the study period.
对 2008 年至 2014 年在山东人类精子库的 5210 名捐精者的精液进行了分析，并评估了精液质量的变化趋势。禁欲 2-7 天后收集精液样本。检测精液量、精子浓度、精子前向运动能力和总精子数。精液量、精子浓度、精子前向运动能力和总精子数均呈显著下降趋势。我们的研究结果表明，在研究期间，该捐精者队列的精液质量下降。
