Single-embryo transfer versus multiple-embryo transfer [PDF]
Reproductive BioMedicine Online, 2009 Despite the progress made in assisted reproductive technology, live birth rates remain disappointingly low. Multiple-embryo transfer has been an accepted practice with which to increase the success rate. This has led to a higher incidence of multiple-order births compared with natural conception, which not only increase the risk of mortality and ...

Embryo Transfer in Rabbits: Figure 1.
Cold Spring Harbor Protocols, 2010INTRODUCTIONBecause there is a particularly narrow time window for implantation in rabbits, embryo transfer in this species requires a high degree of synchrony between the physiological status of the recipient doe and the developmental stage of the embryo at the time of transfer.

Veterinary Record, 1987
The procedure of embryo transfer now in use is described. In the donors, hormones are used to control the time of oestrus and induce superovulation, the preparations used, the methods employed and the phase of treatment are mentioned. In the recipient, synchrony of the oestrus is essential for successful embryo transfer and is achieved by progestagen ...

Annals of the New York Academy of Sciences, 1985
Success and failure of embryo transfer involves at least five major variables: (1) technique, (2) what is transferred, (3) when transfer occurs, (4) endometrial status at transfer, and (5) endometrial support subsequent to transfer. Because of these and other variables associated with programs of in vitro fertilization, it is quite impossible to ...

Best Practice & Research Clinical Obstetrics & Gynaecology, 2019
Embryo transfer is the final and rate-limiting step of the assisted reproductive technique. Few advances have occurred in the last few decades with regard to this procedure. Studies conducted thus far have focused on factors and interventions taking place before, during and after this procedure. These factors are highly varied and range from methods to

At the end of the day, single embryo transfer (SET) is not a big technical innovation, but rather more of an ideology, another way of defining success, not only through pregnancy rates in the fresh cycle. Successful implementation of SET requires that everybody involved in the IVF treatment perform at their best, and some authors claim that the degree ...

1986
Almost 100 years have passed since Heape (1891) reported the transfer of two-cell embryos from an Angora rabbit to the oviducts of a pregnant Belgian hare. This experiment showed that the reproductive tract of the recipient had no effect on the genetic composition of the fetus, because transferred embryos resulted in Angora offspring.

Residual embryos in failed embryo transfer
Fertility and Sterility, 1986One hundred thirteen embryo transfers (ETs) were performed in an in vitro fertilization and ET program of which residual or extruded embryos were found in 17 transfers (15%). Residual or extruded embryos are those embryos found outside the uterine cavity, either at the cervical os, on the vaginal speculum, or remaining in the catheter after an ET ...
