Title: COMPARISON OF SPERM MOTILITY AND FERTILISATION IN VITRO
Abstract: Aim: The aim of this study was to investigate the relationships between computer-aided sperm analysis (CASA), especially the concentration and movement characteristics of progressively motile spermatozoa and fertilization rates in vitro. Methods: Analysis of semen quality was performed using CASA in 36 in vitro fertilization – embryo transfer (IVF-ET) cycles with at least 2 oocytes collected. Sperm quality before and after swim-up procedure was compared between 23 cycles with fertilization rate ≤50% and 13 cycles without fer tilization. Results and conclusion: Our study demonstrated that velocity parameters and motility characteristics of sperms from freshly obtained semen and those after swim up procedure correlated with fertilization rates, indicating that these parameters could be good predictors of the fertilization outcome.
