Comparison of sperm motility between the swim-up and swim-down methods. Siriraj Medical Journal, 2001 May; 53(5): 296-299.http://imsear.searo.who.int/handle/123456789/137389The objective of this study was to compare two methods for the extraction of high motility sperm; the swim-up and swim-down techniques. The result showed that both methods produced greater sperm motility than the original semen. The motility of the sperm was lower in the swim-down method compared with the swim-up method (65.5+11.2% vs 76.5+10.1%; p<0.01).enSperm motilitySwim-upSwim-down methodsArticle
