Blinks, I would email Dr L R and ask for his recommendation on that one. He told me, ideally I should be looking for a donor who produced 15+Good quality eggs which fertilised well with some to freeze.... And that's where I was shot as none of my donors had any ever left to freeze. My frozen donor had two batches of frozen eggs one with 12 eggs and one with 10 eggs... I'm 16 weeks pregnant thanks to one of those little frosties... So eggs left to freeze is something else you should enquire about when looking at your donors stats.
re the smoking thing, I smoked quite heavily when I fell pregnant with my 12 year old. I so regret smoking now, but she is a strong fit healthy girl. In saying that, I did not want my donor to smoke.
