I don't know if this will be any help to anyone on here but I was conceived by donor sperm and I'm now an adult (29). My mum went through the agony of infertility until her and my dad were able to have me via anonymous donor sperm. She had no one to ask about it in terms of what it would be like for me growing up etc. and was worried. It ended up being absolutely fine!
So if you have any questions about what it's like to find out, or to be grow up donor conceived, or how it affects things, feel free to ask!
