Your personal conditions as well as your child’s future both affect when you choose a sperm donor. The sperm donor might not willing to be contacted and might want to remain anonymous. In many states, a sperm donor is not considered as the biological father and has no parental rights for his child. You can even sign an agreement with the sperm donor to remain anonymous and do not having any parental rights with your child. It is a very personal choice and every potential single mom or couple has to decide what they feel comfortable.
