AbstractTo determine whether the mode of embryo transfer (PROST vs IVF) affected the outcome in
intracytoplasmic sperm injection (ICSI) cycles, 237 ICSI cycles (1 06 PROST and 131 IVF) were
analyzed. Several parameters, including patient age, duration of infertility, amounts of hMG used,
number of mature eggs retrieved and injected, fertilization rate, number of embryos transferred,
and clinical pregnancy rate, were compared. Most of the variable factors were not significantly
different, except the mean numbers of transferred embryos which were significantly higher in the
PROST group. The clinical pregnancy rate showed no statistical difference between PROST and
IVF cycles (25.5 and 16.8% ; p = 0.139). This study suggests that even the pregnancy rate in PROST
cycles was slightly higher than IVF cycles, but there was no statistically significant difference
between the two groups.
