Abstract
There has been a troublesome anomaly in the UK
between cash payment to men for sperm donation and the
effective assumption that women will pay to donate eggs.
Some commentators, including Donald Evans in this
journal, have argued that the anomaly should be resolved
by treating women on the same terms as men. But this
argument ignores important difficulties about property in
the body, particularly in relation to gametes. There are
good reasons for thinking that the contract model and
payment for gametes are both inappropriate, and that a
model based on altruism should be applied to both sexes.
