Under the NSW Assisted Reproductive Technology ACT, effective from the 1st January 2010, all sperm donors are required to make their identity available to the children conceived from their sperm donation when the child turn 18 years of age. They must also give written informed consent to their name being included on the NSW Central ART donor registry. Sperm donors are only allowed to create a maximum of five families, including the family/s of the donor. All overseas donors are required to meet the same legislative requirements.
