Ultrasound-guided embryo transfer and the accuracy of trial embryo transfer
Human Reproduction, 2005Studies have suggested that ultrasound-guided embryo transfer (UG-ET) may improve the outcome in IVF; however, several factors may account for the improvement in pregnancy rate. This study examines the use of ultrasound to determine the accuracy of trial transfer (TT) in preparation for ET.Sixty-seven consecutive patients prospectively underwent UG-ET ...

Embryo transfer surgery is an essential step in the process of generating gene-modified mice, regardless of whether the embryos were modified by DNA, RNA CRISPR components, or embryonic stem cells, or whether they were microinjected or electroporated.

Number of Embryos Transferred and Implantation
Annals of the New York Academy of Sciences, 2004Abstract: Multiple pregnancies are considered the most frequent and serious complication of assisted reproduction technology. To reduce the frequency of multiple pregnancies, several centers have adopted a policy of reducing the number of embryos transferred in the uterus, suggesting single embryo transfer.

The high incidence of multiple pregnancy is a major side effect of assisted reproductive technology that has recently given rise to justified criticism from different sides. The reasons for the high incidence of multiple pregnancies are discussed and a brief review is given of the steps that have been proposed to solve or at least reduce the problem ...

Influence of embryo transfer depth on in vitro fertilization and embryo transfer outcomes
Fertility and Sterility, 2004To investigate the influence of transfer distance from the fundus (TDF) on clinical pregnancy rate (PR) and ectopic pregnancy rate.Retrospective cohort. Between January 2000 and December 2001, 699 ultrasound (US)-guided embryo transfers were conducted. Mock transfer was performed to measure uterine cavity depth 1 month before treatment.

Single Embryo Transfer: Significance of the Embryo Transfer Technique
2015Single embryo transfer (SET) has been hailed as perhaps the only foolproof solution to avoid the incidence of multiple pregnancy, a significant complication of assisted reproductive technology (ART). While SET has remained successful in its motive of avoiding multiple pregnancy, the challenge of ensuring a positive clinical pregnancy and eventually a ...
