DOR,age,IVF

Hello, dear doctor. Listened to you podcast and been blown away by your expertise! I am a youthful 45 year old trying to get pregnant. Gotten pregnant 2 years ago naturally, but miscarried in week 9. Had done 3 IVF since. First with birth control, menopur (300 IU), cetrotide from day 4 stimm., HcG trigger. Got 2 follicles, 2 eggs, one embryo (transferred day3). Did not implant. Second IVF birth control, gonal F (300 IU), cetrotide from day 4 stimm, Hcg trigger. Got 4 follicles, 2 ovulated before retrieval, got 1 egg, one was “empty”, fertilised with 2 sperms. Third IVF with letrozole, menopur (300 IU), cetrotide from day 4 stimm, HcG trigger. Had 3 follicles, that were growing very slowly and NO eggs retrieved – all said to be “emptly” follicles. I have to mention I am a vet, so the injections are done properly. I just feel that there is a baby for me in my future and that the protocols are not tailored to my needs. What would you use on me and what do you suggest I discuss with my doctor? Should I do some additional testing? Thank you sooooo much.With love, Maja
