I noticed myself that it seems very rare now a days to see a donor produce 20+ eggs, that all fertilize properly. I've had 2 cycles, 1 was 13 eggs, resulting in 4 embryos on day 3, and 2nd was (split cycle) 5 eggs, 5 on day 5, 2 transferred, 1 frozen on day 6.
I think North America is starting to get a little bit more conservative on the stimulation. And I don't necessarily think it is a bad thing. I think it is wise to take into consideration the donor's future fertility and health. And there is a lot of research out there that says less = more, so I kind of agree with it. However coming from someone who needs DE, I do wish I had like 6-7 embryos frozen waiting for me to try again.
It's definitely a double edged sword.
I hope you end up with a good producer and some great quality embies!
