 Another argument against donor anonymity is that secrecy about origins has the potential to damage the relationships between donor-conceived children and their social parents, especially in cases where the social parent(s) know the identity of the gamete donor(s) Some argue that the strain of having to ‘keep the secret’ is a cause of stress for social parents, and that this stress has a negative impact on familial wellbeing (Landau 1998). A potentially more significant source of family tension is accidental disclosure, especially when donor-conceived children are older. In this latter case, several harms might arise, and may be greatly exacerbated if children were not aware that they were donor-conceived. Children might develop feelings of distrust towards their social parents, and may have difficulty incorporating facts about their genetic history into their personal identity (Turner &amp; Coyle 2000).
