I have named changed for this because it's a ridiculous situation that makes a mockery of real donors.
I have an old friend who has a (now) 2.5 year old son. She's always been single- a few brief relationships but nothing very ling. She is certainly eccentric to put it mildly and has a history of making very erratic decisions.
To cut a long story short she had her son after a (deliberate) one night stand where she was trying to get pregnant. She told our group that she would track when she ovulated each month and then go and find a willing "live donor" (her words). I'm not sure how many moths she did this for before she got pregnant.
The father has no idea and she has no way of contacting him- she doesn't even know his name. She has told her family that she was paired with a sperm donor as they are very religious.
Her intention is simply to tell her son he was donor conceived when he asks. She has no solution to offer to the fact that there is a register of actual donors which this man will obviously not be on.
All of us (friendship group) can see the inevitable damage that this will result in for that poor little boy who will never know anything of his parentage.
She doesn't seem to be able to grasp how it will affect him to know nothing about 50% of himself. She's oblivious to the fact that he will need to have answers and the most upsetting thing is he will never be able to have them. I hope it won't affect their relationship but these sorts of lies can cause deep damage.
The whole thing is one of the most shocking things I've experienced as a friend- I honestly don't know anything I can do to circumvent the future problems. It's heartbreaking.
