Most intended parents use sperm banks (cryobanks) to find a donor. Traditionally, this process was treated as anonymous but, because of at-home DNA testing and widespread information on the internet, truly anonymous donation is not a guarantee. Now, the trend is moving toward more open arrangements. This means that the donor is asked if he is open to contact from the parent, the child (as an adult), or both, and this preference is listed in his profile. It is also generally acceptable to work with a donor who is known to the recipient through family, friend, or community connections. Many states have very specific laws about sperm donation, and it is important that you comply to be sure that the donor does not have parental rights. In arrangements with a known donor it is best practice and provides optimum protection for each party to have an independent attorney, psychological screening, and a written agreement. Your doctor may require this.
