RPMG moves to CGH for PGS for chromosomes

RPMG will now be using comparative genomic hybridization (CGH) for preimplantation genetic screening (PGS) for chromosome screening of embryos (including for sex selection). CGH is a technique that involves amplifying the DNA and uses many thousands of probes to check all 23 chromosome pairs. As long as an intact nucleus is biopsied, it is virtually error-free, whereas with the older

Does preimplantation genetic screening (PGS) improve IVF success rates in women over 35?

Some fertility centers promote preimplantation genetic screening as a way of improving IVF success rates in women over 35 (defining advanced maternal age).

Now a study in the January 2010 edition of Fertility & Sterility shows that PGS does not significantly improve implantation, pregnancy or live birth rates. In this randomized control study from Belgium, the clinical implantation rate per embryo …
