The aim of the study was to determine the level of awareness and acceptance of in vitro fertilization pre-embryo transfer (IVF-ET) patients for freeze-all embryo transfer, improve relevant technical specifications, and optimize treatment results based on medical experience.Questionnaires were completed by women who received in vitro fertilization embryo transfer. A total of 377 valid samples we...

Embryo transfer (ET) is universally recognized as the final and most critical stage in an in vitro fertilization (IVF) outcome (Neithardt et al., 2005; Ghazzawi et al., 1999). The majority of couples (approximately 80%) who undergo IVF reach the embryo transfer stage, yet few pregnancies occur (Mansour & Aboulghar, 2002; Adamson et al., 2006). Although embryo genetic abnormalities (Munne et al....

Aim It was examined whether the single embryo transfer policy makes the treatment period longer for couples to achieve their first live birth by assisted reproductive technology. Methods This study retrospectively analyzed women who started assisted reproductive technology at younger than 40 years of age in the authors' organization. The treatment periods for couples to achieve the first live...

BACKGROUND The true impact of the embryo transfer catheter choice on an IVF programme has not been fully examined. We therefore decided to systematically review the evidence provided in the literature so that we may evaluate a single variable in relation to a successful transfer, the firmness of the embryo transfer catheter. METHODS An extensive computerized search was conducted for all relev...

OBJECTIVE To compare the live birth rate, multiple pregnancy rate, and obstetric outcomes of elective single and double embryo transfers. DESIGN Case series with internal comparisons. SETTING University affiliated hospital, Hong Kong. PARTICIPANTS Between October 2009 and December 2011, 206 women underwent their first in-vitro fertilisation cycle. Elective single embryo transfer was offer...

BACKGROUND The most common complication of IVF is multiple pregnancy, which occurs in 25% of pregnancies following the transfer of two embryos. Single embryo transfer can minimize twin pregnancies but could also lower live birth rates. Our aim was to perform a systematic review of randomized trials to determine the effectiveness of single versus double embryo transfer. METHODS Cochrane Collab...

background: embryo selection is a vital part of in vitro fertilization (ivf) programs, with morphology-based grading systems having been widely used for decades. time-lapse imaging combined with embryo morph kinetics may proffer a non-invasive means for improving embryo selection. we report the first ongoing and chemical pregnancies using time-lapse embryo scope to select best embryos for trans...

Embryo transfer is a multi-step process that involves the production and collection of preimplantation embryos from genetically superior females (called donors) and the subsequent transfer of the harvested embryos into reproductively healthy females (called recipients) for the purpose of establishing pregnancies and producing live offspring. The first successful embryo transfer in mammals was p...

Embryo transfer refers to a step in the process of assisted reproduction in which one or several embryos are placed into the uterus of a female with the intent to establish a pregnancy. Currently this biotechnology has become one of the prominent high businesses worldwide. This technique, which is often used in connection with in vitro fertilization (IVF), has widely been used in animals or hum...
