Hello – I have gone through 5 rounds of freezing embryos with limited success, primarily due to very low maturity rates of my eggs (~25%). For example, I recently retrieved 27 eggs, similar in size, dr. pushed the size greater than 20, used a dual trigger, and only 7 eggs were mature at the time of retrieval. A few more became mature that evening. My question is related to the timing between the trigger and retrieval. Mine have always been 35 hours after which seems to be the norm, but could I benefit from performing the retrieval a couple hours later to give my eggs more time to mature? What is the ideal number of hours in this situation? It seems clear to me that 35 hours is too short for my body. A friend told me her retrievals have been 48 hours after trigger – is this too long?
