Both vitrified cycles. One cycle was from late 2008, xfer in summer 2010. The other FET (summer 2011) was from fall 2010 cycle. BFN both times. I would not take that risk with my money again. I shouldn't have done it last summer. Before the SART report (which was late this year), they told me on the phone that they were seeing 20% success. I should have done the math when SART showed under 15%.
Figure out your tolerance for failure and your budget. We calculated on 20% and figured out that even with travel, that was equal to doing fresh. But under 20%, it wasn't, and I really am sorry we didn't recalculate.
There is a clinic in Sandy, UT that has reasonable prices and great success, including with FET. It's more than CNY, but when you figure in the FET success, it works out better.
