ISCI and Zymot Stories Please!

My first round of IVF resulted in 2 blasts from 9 fertilized. 0 Euploids.

My second round of IVF resulted in 4 blasts from 7 fertilized. I’m still waiting on PGTA.

I was on the same antagonist protocol both times, and the only difference is that we added Zymot and ICSI the second time despite no known MFI.

Should I be feeling optimistic? Is the significantly better blast rate likely attributed to cycle variation or could Zymot and ICSI actually help with blast and (hopefully) Euploid rates even if egg quality is the suspected issue?

Would love to hear your similar stories and outcomes!

Edit: ICSI in the title 😅

UPDATE: 3 out of the 4 blasts came back Euploid! This is beyond my wildest dreams after 0/2 the first round and being told my egg quality is our major problem.
