Factors Affecting an Embryo Transfer Program
A commercially viable cattle embryo transfer (ET) industry was established during the early 1970s. Initially, techniques for recovering and transferring cattle embryos were exclusively surgical. However, by the late 1970s, most embryos were recovered and transferred nonsurgically. Successful cryopreservation of embryos was widespread by the early 1980s, followed by the introduction of embryo sp...
متن کاملFactors Affecting Embryo Transfer Success in Recipient
Recipient age at transfer (less than 525 d old or more than 525 d old), season (fail, winter, spring, summer), method of synchronization (natural or induced), and transfer technique (surgical or nonsurgical transfer) were associated with success of embryo transfer in a log-linear analysis. In a separate analysis, no significant association was found between success of transfer and transfer to t...
متن کاملFactors affecting the successful embryo transfer
The main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. Embryo transfer (ET) is the last step of critically important procedure of in vitro fertilization (IVF) and probably the least successful step in Assisted Reproductive Technology (ART) treatment cascade; though simple in most of the cases, it may pose to be the most diff...
متن کاملThe Comparison Between the Pregnancy Outcome after Easy Embryo Transfer and Difficult Embryo Transfer
Background: The role of embryo transfer (ET) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. In the present study we classified ET technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of the two ET types. Methods: This study was performed retrospectively on 295 infertile patien...
