He is/was my RE and I think he is fantastic. I LOVE, LOVE, LOVE him. I have been through a lot and a tragic loss and he has really been there for me. He truly cares about his patients. I say he is worth the wait and there is a reason why he has the longest wait list in this city. I think you will still have time to cycle, esp. if you already have had all of the testing done. Maybe can you call and ask to talk to one of his nurses to ask specifcally about this? That being said, Dr. Shapiro is also supposed to be a very good doctor. I never worked with anyone but Dr. Toledo. And thank goodness, only because Dr.Shapiro is friends with a lot of friends of mine, and I would be too embarrassed to run into my RE at a friends house/party, etc.,after he has "been in the neighborhood". As much as I love Dr. T, it is an "in office" relationship!

I'm shy that way.
While I was cycling, I was not aware that they were requiring an endo biopsy, although I had a few because I had major lining issues. The first one was done for testing. Then, and this was later, we did an endo biopsy, which they called a "scratch test" to just disrupt the endometrium a bit to help stimulate blood flow. This was done just before you started your cycle. I don't think the scratch test is any different than the endo biopsy other than they are not sending it to the lab to be tested, they are just doing it to improve the lining and possibly chances of implantation, based on a study that originated out of Tel Aviv. That is how I understood it, anyone who knows better, please feel free to correct me. And that was the long winded way of saying that since this biopsy is done just a handful of days before your cycle starts, that won't slow anything down.
Not sure about the mock transfer thing, as I just did it while I had my SHG done, and I was in town. But I think the pp covered that. However, I needed to use a GC this time around and she did not have to come in town prior to the transfer for that. No problems with the transfer. Did an eSET and I am now almost 35w pg (via the GC).
