Campaigns for the widespread use of
single embryo transfer in IVF, he added, would lower the risk of ectopic pregnancy even further by minimising the number of multiple pregnancies.
He is engaged in advanced research projects in computer embryo imaging to improve pregnancy rates, Comprehensive Chromosome Screening (CCS) as a way to
enable single embryo transfer, and in egg freezing.
But to reduce unintended twin births, states across the country should consider requiring insurance coverage of
single embryo transfer IVF, he said.
Building on our extensive and growing body of research into the best IVF practices, we continuously achieve extremely high live birth rates while performing almost
exclusively single embryo transfers, reducing the odds of high - risk multiple pregnancies.
Impact of
single embryo transfer policy on perinatal outcomes in fresh and frozen cycles — analysis of the Japanese Assisted Reproduction Technology registry between 2007 and 2012.
«What we want this technology to achieve is confidence to switch to
single embryo transfers instead of the practice of transferring multiple embryos without [an accompanying] reduction in pregnancy rate,» study co-authors Gayle Jones and David Cram, senior research scientists in immunology and stem cells at Monash University in Australia, wrote in an e-mail.
The first author of the ICMART report, Professor Silke Dyer, a senior specialist in reproductive medicine in the Department of Obstetrics and Gynaecology, at Groote Schuur Hospital and the University of Cape Town, South Africa, said: «The move
towards single embryo transfer (SET) and thus towards greater safety and better outcome for ART is a significant finding.
Dr Peeraer said: «We found that among women treated after July 2003 there was a higher proportion of
single embryo transfer cycles, a higher singleton delivery rate and a lower twin delivery rate (12 % versus 24 %) compared to women treated before that date.»
His current research interests include developing morphologic and biologic markers of embryo viability in order to
enable single embryo transfer and avoid multiple pregnancies; optimizing preimplantation genetic testing; and deriving human embryonic stem cell lines.
After the removal and fertilization of eggs with the use of in vitro fertilization (IVF), some women with multiple embryos (fertilized eggs) may decide to have
a single embryo transferred to the womb even when multiple embryos are available (elective single embryo transfer eSET).
With genetic testing (PGS) 90 % will get only
a single embryo transferred.
We are striving very hard to limit the number of twins, and eliminate the occurrence of higher order multiples (see below) using techniques such as embryo selection and blastocyst transfers, and the introduction of «elective
single embryo transfer».
Our high implantation rates, particularly in our frozen embryo program, allow us to achieve high success rates with just one transferred embryo, and roughly half of all transfers at this center are
single embryo transfers.
Long a proponent of elective
single embryo transfer (eSET), Pacific Fertility Center was a leader with this technique when it was not widely used in the U.S. — perhaps even considered an anomaly.
Increases in embryo cryopreservation, comprehensive chromosome screening, and
single embryo transfer are more adequately captured by the new reporting system.
That's the promise of elective
single embryo transfer (eSET), when combined with comprehensive chromosome screening (CCS) and other technologies.
In some states, including Rhode Island and Massachusetts, insurers not only cover much of the cost of IVF, but also often recommend skipping the Clomid / IUI step in favor of IVF with
a single embryo transfer.
Feil D, Henshaw RC, Lane M. Day 4 embryo selection is equal to Day 5 using a new embryo scoring system validated in
single embryo transfers.
