Comparison of the effects of variables in sperm preparation techniques on pregnancy rates in intrauterine insemination

Abstract

Aim: To investigate the effects of two sperm preparation techniques, density gradient centrifugation (DGC) and swim-up, on thepregnancy rates per cycle and per group in two intrauterine (IUI) cycles.Material and Methods: The retrospective study reviewed 634 patients who presented to Firat University Medical School Hospital andunderwent a total of 1,032 IUI cycles. Group I consisted of 306 (48.3%) patients who underwent a total of 524 IUI cycles betweenJanuary 2012 and January 2016 and Group II included 328 (51.7%) patients who underwent a total of 508 IUI cycles between April 2015and January 2019. The study investigated the effects of technical changes applied to sperm preparation techniques on pregnancyrates in both groups.Results:A significant difference was found between the clinical pregnancy rates of the two groups with regard to the numbers ofpatients and IUI cycles (p
