Bourn Hall Clinic is widely regarded as one of the world's foremost centres of assisted conception and IVF. More than 6,000 babies have been born since Patrick Steptoe and Robert Edwards first opened Bourn Hall in 1980. The third edition of this textbook - which is based on the traditional philosophies of Bourn Hall's comprehensive training program - expands and updates the second edition, published in 1999. The content is comprehensive, covering the assessment of infertile couples and the laboratory and clinical aspects of their treatment by assisted reproductive technologies. The emphasis throughout is on the practical management of patients undergoing assisted conception treatment. This textbook is an essential work of reference for all clinicians and scientists working in reproductive medicine. Included with this edition are many of the Bourn Hall Procedures, Protocols and Information Sheets, which have been formatted on CD-ROM, to enable readers to customize them for their own use.
