I went to RMA-NJ for one cycle and now question their protocol. I am 40 and they definitely pushed doing the PGD testing. It sounded great, we were sucked in, but after the cycle (including two transfers) did not work, we got two more opinions.
Two REs in NYC, one of which is at Weill Cornell, said they would definitely not do PGD testing unless there was a genetic history because it may weaken the embryo. They basically said we have that technology too and could do it, but we chose not to. Also they both said that the RMA process of weeding out embryos based on the lab's criteria/PGD reduces a woman's chance of getting pregnant -- some Day 3-4-5 embryos that they reject may succeed if they were placed back in the natural environment of a woman's uterus. My guess is that the PGD testing is a big money maker for them.
