 The arguments against donor anonymity considered thus far focus on harms that might arise as a result of the practice. Another kind of argument is that individuals have a fundamental right to knowledge about their origins. In the legal literature, some have argued that the UN’s Declaration on The Rights of The Child and the European Convention on Human Rights establishes individuals’ rights to information about the circumstances of their conception, including information about their progenitors (Blyth &amp; Farrand 2004). Apart from appeals to such declarations of rights, some attempts have been made to motivate recognition of a fundamental right to know via appeal to other fundamental goods.
