I thought some people might be curious about what sort of information you get when you have your embryos tested with CGH, so I scanned in my reports.
Here's the report from the lab that did the CGH (click the image to zoom in).
It's noteworthy that every embryo was declared either normal or abnormal. It is possible to get "no result", because the biopsied cell fails to grow and thus there's not enough DNA to get test results. That's one downside of CGH, although we were completely ok with it - worst case we would have thrown out the known abnormals, transferred the known normals one at a time, and then moved on to the unknowns if necessary.
Here's the report from my clinic that tabulates the CGH data (diagnosis column) with the physical grade at Day 3 and Day 5.
You can see that egg #1 produced a genetically normal embryo, but it fragmented by Day 5 and wasn't looking great at Day 3 (grade III).
Embryos #4, #7, and #8 are our good ones. They're genetically normal, and they are Grade 1 expanded blastocysts. We transferred #8, which was as good as embryo as you can get (5AA). Those following along closely can figure out what gender we transferred... #4 and #7 are frozen for future transfers - they're both graded 5AB which is only slightly below a 5AA, still awesome embryos.
We really lucked out that we had 3 genetically normal and physically perfect embryos. They don't always line up so nicely. (see egg #1)
#5 was the laggard that we were hoping would keep growing. It was genetically normal, but was 9-cells at Day 5 and needed to reach blastocyst stage by Day 6 to be frozen. Alas it stopped growing (or didn't grow fast enough).
For comparison, here's the FISH report that we got on IVF4 earlier this year. My clinic used to only offer FISH (tests 9 chromosomes), but recently started working with another lab to offer CGH for patients who want/need it.
Hopefully this is helpful and of interest. I know I would have loved to have seen what a CGH report looks like before I actually had one run on my own embryos. If you have other questions, leave them in the comments and I'll continue to flesh out this post if I have the answers.
