The phrase
"embryo selection" refers to the process of choosing specific embryos in reproductive technology. It involves selecting the healthiest or most desirable embryos to be used for pregnancy, typically to avoid genetic disorders or increase the chances of a successful pregnancy.
Full definition
It may also become increasingly difficult for any argument against any research on early embryos to command a hearing (including arguments against «therapeutic» cloning) as other procedures that
involve embryo selection and disposal become more common.
«Knowing this might occur may improve approaches
for embryo selection and ultimately the success of IVF / preimplantation genetic diagnosis.»
As use of
preimplantation embryo selection grows, for example, there is a diminishing chance that anyone in the mainline will remain willing to throw the first stone at the Goliath of embryonic biotechnology.
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».
CCS
refines embryo selection, offering a means of choosing the best embryos, the most likely to succeed, out of a group.
«One possible explanation is less opportunity for
proper embryo selection due to smaller starting numbers of oocytes, leading to fewer embryos available for transfer.
Using computer - automated, time ‐ lapse photography of embryos in the laboratory during in - vitro fertilization may
improve embryo selection, potentially increasing the chances of pregnancy among women undergoing the procedure, according to new research from the Perelman School of Medicine at the University of Pennsylvania and five other fertility centers.
I have not seen the full details of the study so can not comment on the success rates claimed for this particular method of detected mitochondrial DNA in embryos, but we should remember that many IVF cycles fail because the woman is not receptive, so that
embryo selection no matter how careful will not help.
These comments follow the HFEA's announcement that they are to relax the rules
on embryo selection to allow couples to select an embryo who might be a tissue match for a seriously ill sibling.
In fact, given the thousands of IVF births each year that
involve embryo selection and / or «selective reduction» abortion, one could plausibly argue that we are already there.
This study evaluated the use of the Eeva non-invasive early embryo viability assessment system by IVF laboratory staff during routine procedures and
embryo selection.
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.
