I had my daughter via ivf aged 40 after 2 cycles (first and only FET). Have been trying for a second (aged 41-42 years) over 4 cycles. My AMH is 31 and I have ~35 follicles (no PCOS). My protocols have ranged from 300-450 FSH + orgalutran + single trigger. I only ever get 6-13 eggs with poor fertilisation (1-5 will usually fertilise). I’ve gotten 4 blastocysts over 3 rounds (none on the last), one chemical only. Is it worthwhile continuing to try ivf? Any ideas for increasing fertilisation and blast numbers? Any point in trying iui? Thanks so much for your time!!!!
