Sperm morphology and IVF pregnancy rate: comparison between Percoll gradient centrifugation and swim-up procedures

1 Apr 1991

Abstract excerpt

Many groups currently use two methods for the separation of motile spermatozoa, swim-up (S-up) and centrifugation on discontinuous Percoll gradient (PGC), and comparison of results indicates that PGC is superior. In this study we have attempted to identify the factors explaining this difference. This laboratory has long-standing expertise in seminology, thus the parameters of sperm morphology were the obvious...
