An interesting question on the Reproductive Partners Fertility Forum about possiblility of doing preimpantation geneic screening for chromosomes (PGS) on frozen blastocysts raises some important points.
Q. I currently have frozen embryo's in La Jolla, we have a 17 month old son and are now starting to discuss a second child. My question is if CGH can be perfomed on …
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 …
