Hi mumofsix,

I have had 4 FETs so far, all of them have had Crinone or progresteron support, I think that is pretty standard for FETS. Are you really asking natural versus HRT FETs? I have had both, I believe natural FETs are good if you ovulate naturally, with ET timed following O, HRT if you don't ovulate naturally or have a very long cycle. And there is a combination of each of these, some with puregon and trigger, HRT with progynova etc.

As far as I know there are similar success rates for both natural and HRT FETs, though my current FS has a preference for natural. Again, regardless most FSs would give you progesterone support (Crinone or pessiaries).

Best of luck for your coming cycle.
