Key Points
see Q&A
131
The optimal number of fresh donor oocytes to expose to sperm to maintain the chance of 1 live birth while minimizing supernumerary blastocysts is between 7 and 9?
135
Fertility clinics and patients should consider limiting the number of fresh donor oocytes exposed to sperm to minimize the creation of excess embryos.
136
The number of cryopreserved supernumerary blastocysts increases significantly when more than 9 oocytes were inseminated.
