В этом блоге, тема за 11 января 2010 года:http://infertilityblog.blogspot.com/"The opposite could also happen. Your doctor may see 10 follicles and only retrieve 5 eggs. How is this possible? It’s not uncommon to have fewer eggs than follicles. Some doctors feel that there are some follicles that do not have eggs in them. I think this is possible but not very common. It may also be that the egg is in the follicle but it just does not come out through the needle. This I think is more common. Generally the egg is very loosely attached to the inside of the follicle, but if it’s stuck to the inside, it may evade the needle."
