Hi OP, I'll try to answer all your questions!
My AMH was 10.4 and AFC 12. First round I stimulated very fast and had EC after 8 days of stims. Got 6 eggs, 4 made it to day 5 blasts. 2 were good enough to transfer but not top quality, had both transferred - BFN. No frosties.
Second cycle was 3 months later. In those 3 months I had regular fertility acupuncture, hoped my protein intake (I'm a vegetarian), took ubiquinol and reduced my work stress massively. For the cycle they changed my meds a little to try to slow down my stim phase as stimming too fast lowers the egg quality. We also added testosterone gel which can help with egg quality, and I had the endo scratch. I ended up with 9 days of stims and we got 12 eggs, 7 day 5 blasts, 2 top quality hatching blasts transferred which resulted in my twins. 2 more very good blasts frozen. One of those didn't stick but the second transfer was successful and 20 week scan yesterday showed that everything is good so far. So yes, 3 good embryos from that one round of IVF. I also ended up with OHSS but it was worth it!
Both cycles were short protocol, standard IVF, no ICSI and we had 100% fertilisation each time with my DH's average quality sperm. Whether or not you need ICSI should be advised by your clinic based on your DH's SA results though.
I don't know much about mild IVF but believe it is mostly useful where the woman has very low AMH and isn't likely to produce many eggs anyway. I'm not sure which would be more beneficial when you have decent AMH as you do, because you will likely get more eggs to choose from which might give you better odds IYSWIM? Maybe someone who knows more about mild IVF will be along soon to give you better advice on that 🤞
I was given 15-20% change of success of a single baby! Feel free to ask if you have any other questions and good luck!
