This is one of a series of news items from abstracts of studies presented at the Annual Meeting of the American Society for Reproductive Medicine as complied by Dr. David Meldrum, Scientific Director of Reproductive Partners. We appreciate the enormous amount of work it takes to compile and comment on these abstracts.
One of our greatest challenges has been …
Two Reproductive Partners physicians have been invited to China to present the latest advances in fertility treatment and screening for genetic diseases at a major hospital in Bejing. Drs. Bill Yee and Greg Rosen are currently lecturing on preimplantation genetic screening, molecular technology to screen for a variety of recessive genetic diseases and criteria for maximizing the success rate …
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 …
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 …
