Hi! I'm 43 with one child (conceived a year ago naturally) and want to try for a second. I have 28 frozen eggs in the bank (frozen aged 40). I seem able to get quite pregnant quite easily but have had 3 early miscarriages (one recently, after first child was born). We could continue to try naturally but because time is of the essence I think we should use the frozen eggs (we are planning to start the process in about 4 months, I am still breastfeeding which Ive heard reduces the chances of successful pregnancy but will be closer to stopping by then). Ive had mixed advice on PGT testing with one doctor telling me it would require me to refreeze embryos (which has unknown risks) and that the benefits in terms of reduced miscarriage risk are negligible. My questions are therefore: 1) Should I proceed with PGT testing - will it save us time/trauma by reducing miscarriage risk? 2) How many eggs is it advisable to defrost at time? Thankyou so much for any advice from people who have researched these issues:)
