Abstract

Objective: ssessment of pronuclear embryo transfer efficacy (Day 1) compared to Day 3 embryo transfer at the Infertility and Assisted Reproduction
Unit, Ob/Gyn Dept, “Sapienza” University, Rome, Italy.
Material and method:A retrospective study comprised of 461 ICSI patients were retrospectively evaluated between May 2010 and December
2011. In 183 cycles embryo transfer was performed 26-28 hours after ICSI
(Group A) and in 278 cycles embryo transfer was performed on Day 3
(Group B). Zygotes at pronuclear stage were classified according to a new
simplified criteria. Only “good quality” embryos were transferred in both
groups.
Results:o statistical significant differences were found between group 1
and group 2.
Conclusion:In conclusion, pronuclear “good” embryo transfer remains a
viable and easy option for IVF, resulting in clinical pregnancy and delivery
rates comparable to those reported from Day 3 transfer.
