Dr Lei at Genetics and Health has posted this great video from UCSD on when it might be good to see a geneticist/genetic counselor (I like Genomic Counselor better).
In addition I just received and email from a friend of mine (Info available upon request and his approval). He has sent me a good editorial and review of the concerns of PGD. It is entitled.
NATUREVol 4451 February 2007 "The First Cut" The risk is there but so is the benefit.
"Meanwhile, patients are left in a quandary
about whether the small, unproven risks are
worth taking. To avoid having a child with a
severe genetic disease, it is probably well worth
undergoing PGD; but for aneuploidy screening
the decision is less clear. At the very least,
experts say, practitioners should spell out the
risks and benefits of the procedure to would-be parents"
