Day 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...
متن کاملDay 4 embryo selection is equal to Day 5 using a new embryo scoring system validated in single embryo transfers.
BACKGROUND Single embryo transfers (SETs) require the most viable embryo from a cohort to be selected. Day 4 embryos may provide a selection advantage similar to blastocyst transfer as embryos are replaced post-embryonic genome activation and into the uterus where they would normally reside. However, there is currently no adequate morphological system to assess Day 4 embryos. Therefore, we deve...
متن کاملReduced Ectopic Pregnancy Rate on Day 5 Embryo Transfer Compared with Day 3: A Meta-Analysis
OBJECTIVE To compare the risk of ectopic pregnancy (EP) after embryo transfer on day 3(D3-ET) and day 5(D5-ET). DESIGN Meta-analysis. PATIENTS Women with pregnancy resulting from in vitro undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).

متن کاملI-29: Can Fresh Embryo Transfers Be Replacedby Cryopreserved-Thawed Embryo Transfers inAssisted Reproductive Cycles? A RandomizedControlled Trial
Background: Controlled ovarian stimulation (COS) has been shown to advance endometrial maturation and affect adversely implantation in assisted reproduction technology (ART) cycles. It has been reported that there is a better embryo-endometrium synchrony in frozenthawed embryo transfer (FET) cycles than fresh embryo transfer (ET) cycles. The Background of this study was to compare ongoing pregn...
متن کاملThe successful use of pronuclear embryo transfers the day following oocyte retrieval.
A retrospective analysis of results from 114 initiated in-vitro fertilization cycles utilizing pronuclear embryo transfer is presented. Patients were unselected for age or infertility criteria, constituted a continuous series and were grouped according to response to stimulation (Group 1, ideal; Group 2, suboptimal) or ovarian reserve (Group 3, poor). At 16-18 h post-insemination, embryos were ...
