The incidence of multiple pregnancies has increased with the increasing use of assisted reproductive techniques. This super-specialty title intends to cover basic epidemiology, associated complications and management of multiple pregnancy.

Key Features

The aim of this book is to provide a comprehensive, up to date and an evidenced-based discussion of multiple pregnancy and recent advances in its management. The chapters are divided in such a way that all three trimesters are discussed separately with all the relevant details. Pedagogical features like learning objectives, key learning points, text in highlighted boxes throughout the chapters provide the essential knowledge.

Ideal for postgraduate students – MS and DNB, practitioner segment in obstetrics and gynaecology
