Hi there;
The law changed recently about the anonymity of the egg sharer;, here's what I found on the net;
From 1st April 2005, the Human Fertilisation & Embryology Authority (HFEA) requires all gamete donors to provide identifying information. This information will enable the HFEA to inform a donor in the future of any enquiries made by a child that has been born following a donation when that child reaches the age of 18. The HFEA will not disclose any information without first contacting the donor. Gamete donors may, if they wish, include a pen-portrait of themselves as a person at the time of donation.
hth,
