The Pregnancy Outcomes of Day 2 versus Day 3 Embryo Transfer: A Cross-Sectional Study
Background The objective was to evaluate whether extending the embryo culture period from 2 to 3 days would yield a more optimal selection of viable embryos, thereby increasing the pregnancy rat. MaterialsAndMethods We have retrospectively analyzed pregnancy rates in the patients who had embryo transfer either on day 2 (582 patients) or on day 3 (387 patients) post-insemination over a 10-month ...
متن کاملDay 3 versus day 5 embryo transfer: a prospective randomized study.
Transfer of embryos at the blastocyst stage has been associated with exceptionally high implantation rates. There are, however, only a few prospective randomized studies comparing day 3 versus day 5 embryo transfer. Furthermore, the number of embryos replaced in the day 3 group transfer is often higher than the number of blastocysts replaced, thereby affecting implantation rates. A total of 118...
متن کاملA prospective randomized study: day 2 versus day 5 embryo transfer.
BACKGROUND This randomized controlled study was performed in an unselected IVF/ICSI population to test the hypothesis that blastocyst transfers result in higher clinical pregnancy rates (CPR) per oocyte retrieval when compared with day 2 transfers. METHODS Blind randomization for transfer on day 2 (group 1) or day 5/6 (group 2) was performed before stimulation. Oocytes and embryos were cultur...
متن کاملA Comparative Analysis Between Day 2 and Day 3 Embryo Transfer in IVF/ICSI: A Retrospective Cross-Sectional Study
Objectives: Although the fertilization and cleavage rate of implanted embryos is about 70%-90% in most patients, only a small number of embryos grown in vitro have the potential to implant. This indicates that many factors are responsible for a successful implantation, including obtaining viable embryos for transfer. This study aimed to examine the clinical results of pregnancy and implantation...
متن کاملDay 3 embryo transfer versus day 5 blastocyst transfers: A prospective randomized controlled trial
OBJECTIVE This study aimed to show whether transferring day 5 embryos resulted in higher implantation and pregnancy rates than transferring day 3 embryos in Turkish women undergoing an intracytoplasmic sperm injection (ICSI) cycle. MATERIALS AND METHODS A total of 190 women who had ICSI after retrieval of more than four oocytes on the day of fertilization check were randomly assigned to under...
