 If the psychological harms arising from donor-anonymity are socially constructed, then prohibiting anonymous gamete donation may exacerbate the harms suffered by donor-conceived children. This is because such a prohibition could further reify the importance of biological ties (sometimes referred to as ‘biologism’), which is what gives rise to the harm in the first place (Melo-Martín 2014; Leighton 2014; Haslanger 2009). By signalling the importance of biological ties, prohibiting donor anonymity might further stigmatize those raised by non-biological parents.
