Hiya
My clinic does two day transfers. I am not sure that is up for negotiation.
But I think if you want to change the protocol you are on you should ask. It won't hurt and you may just get what you want! Is there any reason you want to change?
I was told that it's all down to the embies themselves. My clinic prefers to transfer day 5's, but if there is one that needs the help of it's mum at day 3 they will put it in early..... I haven't actually been through it yet though.
I think it depends on each individual clinic, mine does day 5 blastocysts. That said, I dont see why you couldnt ask for your preference, they will have reasoning behind why they prefer a particular day and can explain this.
Diff clinics will prefer diff protocols as their scientists and techiniques will be more specialised in one area...each type of growth scenario requires diffeent techniques and cultures etc etc.
For example here in melbourne MOnash IVF specialise in blast transfers whereas MIVF specialise and get similar results with three day tansfers.....all clinics should be able to grow to any stage however and you need to consult with your doctor if you want to change your protocol. At the end of the day it is really the scientists who make the final decisions on which stage to take the embryos to....if you have embies they are trying to culture to blasties and they are not looking so hot they may make a recommendation to the doctors to put them back at day three or somethin like that......so really it should be a collaborative decision based on all the data they have available including the succes or otherwise of your past cycles....
In short, talk to your FS and see what they say....
