BW, when I had my stim cycle I was told the aim was to collect 8 to 10 eggs, not a 'maximum' amount. I think the goal is something of a trade off between egg quality and quantity, and 8 to 10 was the number that the clinic had found to give optimal results. Mind you, the stim process can't be completely controlled and the number of eggs actually collected may be well outside of this range (and still successful). And there may be differences in approaches and experience for individual clinics/labs.

I agree with Melbo that you could ask for more info about this. I'm sure a specialist and clinic would be willing to listen to a patient's concerns about excess embryos because of their beliefs. I found mine to be very open to all sorts of weird questions that I threw at them.

PS I'm not an expert on this stuff...others may well know more than me!
