摘要：

Two methods of density gradient centrifugation, Percoll (P) and mini-Percoll (MP), were compared with the swim-up technique for preparing spermatozoa from each of 40 abnormal semen samples. P and MP produced similar results with a mean recovery of spermatozoa with progressive motility which was significantly higher (18-19%) than that achieved with swim-up (5%). However, the swim-up method resulted in the recovery of spermatozoa with a higher mean motility (89 versus 58%), velocity (69 versus 56-mu-m/s), percentage with normal morphology (22 versus 16%) and intact acrosomes (61 versus 36%) than P and MP. The mean amplitude of lateral head displacement was the only characteristic of spermatozoa in semen which correlated with the recoveries of motile spermatozoa. Combining MP and swim-up methods for 10 samples produced a higher recovery (11 versus 6.9%) of spermatozoa with significantly better mean motility (94 versus 87%) than did swim-up alone. Although P and MP resulted in greater yields of motile spermatozoa than the swim-up preparation, the latter procedure selected higher proportions of spermatozoa with improved characteristics (velocity, intact acrosomes and normal morphology) which correlate with fertilization rates in vitro. It is concluded that P and MP are not superior to swim-up. However, sequential MP and swim-up preparation improves yields of high quality spermatozoa from some abnormal semen samples and therefore has potential for improving fertilization rates.
