What’s the optimal endometrium thickness for FET?

[blahblahetc]

Mine measured 9mm, reading mix messages from
Google.. is it quite “bespoke” and if so, based on what? Thanks!

I believe 9 mm or above is ideal. On my last FET dr waited I was 8 or 9 mm then 5 days after planned the FET so it was already a bit thicker by transfer time

I’m not sure there is a cut off really, the literature would suggest that anything <7mm is not ideal, but my clinic are happy with anything over 6mm on day of progesterone start or trigger (for frozen). It’s important that it has a trilaminar appearance more than anything - it will continue to thicken with the progesterone. I would be very happy with 9mm. Mine was 8.6mm on day of transfer and I have just got a BFP. Good luck 🤞

Thanks and congrats! @GB844

I wondered about this but was reassured anything over 7mm was fine. Also found this table in a research paper that was interesting:

www.ncbi.nlm.nih.gov/pmc/articles/PMC5794374/

This was the research paper

9mm is good. When I had my FET they wanted my lining to be more than 8mm to book the FET. I was just under so they made me wait a few days. Lining at the next scan was 10mm so they arranged the FET x

Mine was a poor 6.1mm, the cut off was 6mm but against the odds it worked

Congrats! @Granolabowl

Your message reminds me of the saying 'Nature finds a way' if it's meant to be...

According to the Dr Szlarb it should be min. be 7 millimetres (source: Perfect lining for embryo transfer )
