"Building a Family with the assistance of donor insemination" by Professor Ken Daniels. This one dealt mainly with donor insemination (obviously given the title but Prof Daniels work is on DS and DE and has been published in journals as well if getting hold of the book is hard. He's a New Zealand prof of social work who has studied donor conception (and the experiences of donors as well as recipients and donor conceived offspring) for about 30 years. His studies have been done worldwide so aren't limited to the New Zealand context despite him being based there. More info on him and publications here:
"Experiences of donor conception: Parents, offspring and donors through the years" by Caroline Lorbach. Jessica Kingsley Publishers (www.jkp.com) Lorbach is herself the parent of 3 donor conceived children and was a founder of the donor conception support group in Australia in the 80s. Her book has sections on male infertility, female infertility and the third section is on parenting donor conceived children and the experiences of adolescent and adult donor conceived people growing up.
Both books are very much "tell" but mainly "tell child" while respecting the child's right to privacy beyond that. So, maintaining an open discussion within the family - based on the child's questions if any - about the donor conception and very much making it a "miracle" or gift, rather than a "secret".
(ps - I never watch Oprah. She is anti-ART ? I wouldn't have thought that based on her public image....)
