Ok, maybe not so many....there is only one study of 4 patients at CHR in NYC had success with G-CSF. But Dr. C office said it is a "new" thing that they have just started using. Dr. C believes in the t-cell balance not being correct due to age in older women. He advocates using progesterone to help the NK cells in uterine lining. Sounds like the correct t-cell balance helps keep the NK cells away from attacking the embryos?
BTW, for that mini IVF in December I had a CP from it so I attribute it to the G-CSF fluffing my lining and balancing out the t-cells.
