generation sequencing to select an embryo for in vitro fertilization.
This birth marks the first time that sequencing has been used to screen
embryos for IVF, a process that generally sees only around 30 percent of the
embryos that are selected actually successfully implant, likely due to
chromosomal or genetic defects.
Although other genetic tests screening methods have already been introduced
to identify candidate embryos, they have drawbacks, according to the
European Society of Human Reproduction and Embryology.
The method used to select the embryo in this case, developed by Dagan Wells
of the NIHR Biomedical Research Centre at the University of Oxford, has
overcome some of the current obstacles, according to ESHRE.
This technique has enabled the production of complete chromosome information
that reveals abnormalities that often are responsible for miscarriage, and
for serious gene defects to be found.
The analysis also takes around 16 hours, which means embryos do not need to
be frozen while they wait for lab results, and it could "greatly reduce the
costs of embryo screening, which is an expensive add-on to IVF," ESHRE says.
The child, Connor Levy, was born in Philadelphia last month, the BBC reports.
"Next generation sequencing is a way which could make chromosome testing
more widely available to a greater number of patients, improving access by
cutting the costs. Our next step is a randomized clinical trial to reveal
the true efficacy of this approach - and this will begin later this year,"
Wells says. | P******d

男女任意， 再放到妈妈肚子里
如果以前有这技术， 邓文迪就可以生N多男孩了， 现在王菲可以做这个， 给李亚鹏生
个儿子
