Assessment of two devices for in vitro preparation of human sperm

The aim of the study was to assess and compare the efficiency of the ZSC-II versus the Sperm Select techniques in preparing human sperm from normozoos permic patients for use in intrauterine insemination and other assisted rep roductive technologies. Twenty-five patients were included in the study. Se men was collected at intercourse and processed via 2 sperm preparation meth ods. Recovery of motile sperm and other sperm qualitative measurements were evaluated before and after ZSC-II and Sperm Select sperm preparation. Sper m qualitative measurements were not significantly different after the ZSC-I I and Sperm Select procedures (p > .05). Differences (p < .05) were noted b etween the 2 procedures in the number of sperm recovered A higher survival rate (longevity test, 72 h) was observed after ZSC-II sperm preparation and recovery. The ZSC-II procedure yielded higher total motile sperm than the Sperm Select. The superiority in longevity may suggest possible advantages in obtaining higher fertilization and pregnancy rates.
