Finding the identity of an anonymous sperm donor is possible only if it was an open sperm donation. If this was the case, the donor-conceived person will be able to find his or her bio-dad. In those countries where this option is allowed, the person is allowed to find out about the donor once he or she turns 18, and not earlier.
How can you find your biological father if he was a sperm donor?
