I've found a lot of conflicting information, too. I have yet to finalize my treatment plan, but I'm pretty certain it will be short protocol. I'm going with Serum, in Athens. I am very happy with my choice and feel I will get the best care there, my only negatives are that it is very far away (I'm in Washington State) and the length of time I have to be there. Serum says long protocol can be very harsh on our older ovaries. They have found that gently stimulating women our age yields higher quality eggs, though maybe not higher quantity.
I'm so excited for you! And very happy to hear so far you're responding well! Please keep me updated, if you like.
Best of luck :-)
