British doctors are using a new technique to screen embryos for genetic flaws prior to implementation.
The new [more] technique, developed at Guy's Hospital and St. Thomas' NHS Foundation Trust, allows embryos to be screened and only the healthy ones implanted.
The Times of London says pre-implantation genetic haplotyping (PGH)is an improvement on pre-implantation genetic diagnosis (PGD) because it doesn't require a precise knowledge of the genes causing the problem in a family. The technique is also useful for X-linked disorders.
Until now, selection for X-linked disorders has meant male embryos were discarded in favor of female ones, the newspaper said. PGH enables healthy male embryos to be identified.
