ABSTRACT
Objective To investigate the effect of sperm preparation in male infertility on sperm morphology and DNA fragmentation index(DFI). Methods Four hundred men were divided into the groups of fertile , teratozoospermics and unexplained subfertility. Sperm morphology and DFI were analyzed before and after the sperm preparation. Results Sperm abnormal morphology and DFI in the infertility group were higher than those in the fertile group ,but significantly decreased after sperm preparation. The method of density gradient separation results in obtaining better sperm(P<0.01). Conclusions Compared to the method of swimming up ,the method of density gradient separation could result in obtaining sperm with improved normal morphology and DNA integrity.
