Single Day 2 embryo versus blastocyst-stage transfer: a prospective study integrating fresh and frozen embryo transfers.
BACKGROUND Whether extended culture allowing selection of embryos with high development potential has any advantage over cleavage-stage embryo transfer remains a matter of debate. Among the currently unsolved questions, the cumulative delivery rate resulting from fresh and frozen embryo transfers needs to be taken into account in both strategies. The aim of our study was, therefore, to compare ...
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...
متن کاملThe 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 کاملComparison of pregnancy rate between fresh embryo transfers and frozen-thawed embryo transfers following ICSI treatment
BACKGROUND The use of assisted reproductive technology (ART) is increasing in the world. The rate, efficacy and safety of ART are very different among countries. There is an increase in the use of intra cytoplasmic sperm injection (ICSI), single fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET). OBJECTIVE The objective of this study was to compare pregnancy rate in fresh ET a...
متن کاملComparison of clinical outcomes between fresh embryo transfers and frozen-thawed embryo transfers
BACKGROUND Advances in embryo culture technology and cryopreservation have led to a shift in in vitro fertilization (IVF) from early fresh or frozen-thawed cleavage embryo transfer to fresh or frozen-thawed blastocyst stage transfer. OBJECTIVE To compare the clinical outcomes of fresh embryo transfers and frozen-thawed embryo transfers. MATERIALS AND METHODS In this retrospective case contr...
