I honestly thought the reason they had such a limited selection of donors for the 1:3 program was because those donors were proven to be the super high producers, reacted well to stims, followed all directions, and had already shown pregnancy successes. Otherwise why not open up the 1:3 pool to include all available donors they have, proven or not? Then I wonder, are these 1st time donors even told they are being put in the 1:3 program where they are about to be stimmed very heavily to have enough eggs for 3 recipients.
I'm not "down" on using an unproven donor BTW, did that myself elsewhere and took the risk too. I'm just surprised a clinic would test a newbie who has never had stims before by putting her in a 1:3 program.
