Compensation paid to egg and sperm donors in the United Kingdom could be increased to include a payment for inconvenience, in a bid to tackle an acute shortage of donated gametes. The Human Fertilisation and Embryology Authority (HFEA), which regulates infertility treatment, raises the possibility in a review of its policies on egg and sperm donation launched on 17 January. European law bans payment for donated gametes but allows donors to be compensated for expenses, loss of earnings, and inconvenience. Current HFEA rules allow egg donors to be reimbursed for loss of earnings and expenses, such as travel costs, up to a maximum of £250 (€300; $400). But nothing can be claimed for the physical inconvenience that gamete donors experience, even though egg donation is invasive and sperm donation time consuming.
