Abstract
Two sperm preparation methods, a multiple-tube swim-up and Percoll-gradient centrifugation, were employed in our human in vitro fertilization program. The fertilization rate of these two sperm preparation methods was compared when they were employed in semen samples of <60 million motile sperm/ml. The results described here suggest that both of these methods gave a similar fertilization rate in these semen samples, i.e., 72±8% for the Percoll-gradient centrifugation method and 66±8% for the multiple-tube swim-up method.
