I'm looking into the possibility of donating eggs in return for subsidised treatment. I have had one child naturally. I'd like to know if any of my donated eggs would result in a child, get a photo and the opportunity to tell the parents/child about me and my daughter and get a letter once a year. I definitely wouldn't feel like I'm mum and be demanding cuddles etc but I'd like to know that my egg had become a much loved, happy child. Is this a thing or is it all totally anonymous unless, say, you're donating eggs to your sister?
