23 January 2012 - by Stevienna de Saille

Book Review: Precious Babies - the author responds

23 January 2012 - by Kate Brian

I was delighted that Rachel Pepa's review of my book 'Precious Babies' concluded that it had much to recommend it as a guide to having children after fertility problems as that's exactly what the book is intended to be.

14 November 2011 - by Dr Sue Avery

The general public has been well informed about the HFEA's proposed changes in compensation for gamete donors.

Ethical principles and the HFEA's donation review

07 November 2011 - by Professor Stephen Wilkinson

At a public meeting on 19 October, the Human Fertilisation and Embryology Authority (HFEA) decided to move to a 'flat rate' system of monetary compensation for egg donors. The HFEA also decided to leave the regulations governing egg sharing substantially unchanged.
