two souls - IVFA, not SIVF/Genea (they don't do anonymous donor)
When we got to the top of the list there were 4 profiles available. This was before they sourced US sperm that complies with Australian disclosure laws.
Our wait (9 months, but were told to expect 1 year) isn't relevant as it was before the US sperm.
We found our perfect donor in the 4 profiles we were initially given, so I don't know how quickly new profiles are offered if you don't find your donor in the initial batch.
We DID find it really emotional not finding sperm - but then again we were given "almost certain" chances based on hormones and size. But I think it's best for you to have the donor backup. You are ready for donor, and IF the emotions are too great to proceed with transfer that cycle then hopefully you'll be able to bank some frosties to use later. Frozen embies are better than frozen eggs.
