The use of rights based arguments to justify claims that donor offspring sh
ould have access to information identifying their gamete donor has become i
ncreasingly widespread. In this paper, I do not intend to revisit the debat
e about the validity of,such rights. Rather; the purpose is to examine the
way that such alleged rights have been implemented by those legislatures th
at have allowed access to identifying information. I will argue that seriou
s inconsistencies exist between. the claim that donor offspring have a righ
t to know the identity of their gamete donor and the way such a right is cu
rrently met in practice. I hope to show that in systems where non-anonymous
donation is practised, an. understanding of the proclaimed right of donor
offspring to know their genetic identity is one composed of two different r
ights - the right to know the circumstances of their conception and the rig
ht to information identifying the gamete donor-can provide important insigh
ts into this important area. of public policy.
