background: recurrent implantation failure is one of the most issues in ivf cycles.some researchers found that beneficial effects of endometrial scratching in womenwith recurrent implantation failure, while some authors demonstrated contrary resultsobjective: the present study aimed to investigate the effect of intrauterine. salineinfusion as a form of endometrial injury, during fresh in vitro ...

Objective Women undergoing IVF cycles should go successfully through multiple points during the procedure (i.e., implantation, clinical pregnancy, no spontaneous abortion and delivery) to achieve live births. On the other there is a need to consider previous reproductive outcomes and as well as the current cycle. In this study, data on multiple cycles and multiple points during the IVF cycle ar...

BACKGROUND The use of ultrasound-guided embryo transfer has been reported to affect success rates in some centres but not others. In a prospective study, we examined the influence of ultrasound guidance in embryo transfer performed on different days after oocyte retrieval. METHODS Two different methods of embryo transfer were evaluated in 1069 consecutive transfers. The ultrasound-guided embr...

BACKGROUND It has become an accepted procedure to transfer more than one embryo to the patient to achieve acceptable ongoing pregnancy rates. However, transfers of more than a single embryo increase the probability of establishing a multiple gestation. Single-embryo transfer can minimize twin pregnancies but may also lower live birth rates. This meta-analysis aimed to compare current data on si...

BACKGROUND/AIMS Catheter injection speed affects depth and placement of the embryo into the uterine cavity and is shown to be highly variable in, and between, subjects in a manually performed embryo transfer. In an effort to standardize the injection speed during embryo transfer, we developed an automated transfer pump: the pump-regulated embryo transfer (PRET) device. In this randomized contro...

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....
