FET process and thawing frosties

[Malyna]

Have got three frosties was wondering how the FET work. I understand that they basically track you during your cycle, give you a trigger injection and then implant, but I have no idea how the whole defrosting works.

Would love to hear what happened with you, so I can get an idea of the process etc.

If say the first egg doesn't survive the defrosting process, do you have to wait an entire cycle for another one to be thawed?

Also I had to boost my progesterone (is that the hormone? cant' remember) during my first pregnancy. I'm guessing I'd probably need this again? Or maybe not because they aren't nuking my 'natural' hormone?

Yes I'm going to see the specialist again soon, but I'm so darn curious at the moment and a little impatient
Thanks

Hi Malyna

At our clinic I had bloods taken to determine O and then the frosty was transferred 5 days later. Those were the cycles that were 'unmedicated', I also had one with meds done but it was very similar anyway.

If they thaw one embie and it doesnt survive the thaw then they start the process over with the next embie, and so on and so on until they get a viable one to transfer. So unless all 3 do not thaw then you will get a transfer that day.

Progesterone supplements are are very common and I *think* (sorry its all so long ago) I used them for all IVF/ FETs etc etc.

HTH a little, if I havent explained something or you want more detail just sing out Good luck with it!

So, say for example that on FET number 1, the frostie one doesn't make it past the thaw process, do I have to do another FET cycle (wait another month et al) before I have the next one thawed or can they just thaw another one on the first FET?

Thanks LD Trying not to freak out about the FET because I really had a terrible time on the full IVF and I know I won't be able to do it again, not with a toddler to look after.

FET are not as full on as a full IVF cycle, so try not to stress

No, you dont have to wait a whole extra month. They will thaw as many as it takes to get a viable one on the first FET day

I asked the same question about the thaw (I have had far too many medicated FET's, and the embryologist told me that they know within 30 minutes if the thaw has worked because the dead cells are brown and easy to see - which means if there are over their ratio (my clinic says if over 60% of the cells have died they won't transfer) - they will simply go to the next 'best value' embryo, check back on it to see if the cells have initially thawed OK, then leave it in the culture for the transfer the following day (the timing of this all depends on your clinic - mine thaws them the afternoon before a morning transfer). This means when you have the transfer they can tell you if the embryo has continued to grow which is obviously a good sign.

Good Luck with your FET's - my little frozen bubsicle is having his afternoon nap as I type this and my fresh transfer little girl is at daycare!
