Updated in light of recent research findings on fertilization, implantation and early pregnancy, this new edition combines the expertise of a wide range of internationally renowned authors to produce an authoritative, multidisciplinary approach to the management of first-trimester complications. Several international guidelines and consensus statements have been released since publication of the first edition and this has stimulated new focussed research questions that are addressed. The book's key recommendations provide clinicians with the tools to improve the patient's experience of the management of first-trimester complications. By combining essential elements of scientific research and clinical care, Early Pregnancy continues to set a benchmark for evidence-based management and will be essential reading for obstetricians, gynaecologists, neonatologists, ultrasonographers, and nurses seeking an understanding of the reproductive science of early pregnancy.
