Abstract

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 fertilization.
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.
