The influence of frequent ejaculation on sperm quality in 96 men with oligozoospermia, asthenozoospermia or oligoastenozoospermia was investigated. Ejaculates were produced by each patient in short period of time (4-6 hours). In oligozoospermic group (n = 31) semen characteristics were similar between two ejaculates. In asthenozoospermic group (n = 27) the motility and the total motile sperm count increased significantly in the second ejaculate (32.1% 5.6 vs. 48.0% +/- 7.1 and 36.7 mln +/- 5.6 vs. 47.8 mln +/- 7.6 respectively). Similarly in oligoasthenozoospermic group (n = 38) the motility and the total motile sperm count increased significantly in the second ejaculate (28.1% +/- 5.3 vs. 44.2% +/- 6.2 and 7.1 mln +/- 1.2 vs. 11.3 mln +/- 2.7 respectively). In three groups, pooling two ejaculates increased significantly the total motile sperm count by 58.1%-136.6% comparing to first ejaculate. Pooling two sequential ejaculates from subfertile men is a simple method to increase the quality of sperm for assisted reproduction techniques.
研究了频繁射精对96名少精子症、弱精子症或少弱精子症男性精子质量的影响。每位患者在短时间内（4 - 6小时）采集两份精液样本。在少精子症组（n = 31）中，两份精液样本的精液特征相似。在弱精子症组（n = 27）中，第二次射精时精子活力和总活动精子数显著增加（分别为32.1%±5.6 vs. 48.0%±7.1以及3670万±560万 vs. 4780万±760万）。同样，在少弱精子症组（n = 38）中，第二次射精时精子活力和总活动精子数也显著增加（分别为28.1%±5.3 vs. 44.2%±6.2以及710万±120万 vs. 1130万±270万）。在三组中，与第一次射精相比，将两份精液样本合并后总活动精子数显著增加了58.1% - 136.6%。对于不育男性来说，合并两份连续的精液样本是一种提高辅助生殖技术中精子质量的简单方法。
