Hi BW,
I just wanted to correct what I said about the CREI, as I just looked it up on the internet and it is an Australia/NZ certificate that Obstetrician/Gynaecologists can do, Seems that you will only find them attached to IVF clinics as a requirement is to be working with infertility for a large percentage of their time. If you google CREI you will see a result titled Certificate in Reproductive Endocrinology and Infertility. the file it points to has a list of doctors with that certificate in each state. Perhaps the ones that don't list it after their names have done something similar overseas and don't list it as would not be easily recognised.
I don't think Keen's doctor is on the list but I believe he is overseas trained so may haev done the equivalent overseas.
