ABSTRACT

Conclusion:

Retaining the embryos in culture for 3 days had no negative influence on pregnancy outcomes. Embryo transfer may be performed either on day 2 or 3 according to the work program of the clinic.

Results:

Embryo qualities were similar between groups (p=0,828). Although pregnancy rates tended to be higher in the 2-day transfer group, it was not statistically significant (p=0,18). Azoospermia and the number of retrieved oocytes were predictive factors for a favorable outcome (p=0,001).

Methods:

Individuals admitted to our clinic due to of male factor infertility between February 2006 and May 2010 and who underwent ICSI with the antagonist protocol were included in this study. Pregnancy rates between days 2 and 3 after embryo transfer were compared.

Objective:

The aim of this study is to investigate the effect of embryo transfer of days 2 and 3 on pregnancy rates in patients undergoing controlled ovarian hyperstimulation/ intracytoplasmic sperm injection.
