The fifth edition of NMS Obstetrics and Gynecology has the same primary goal of the previous edition, and indeed, the entire NMS series in general: to provide the most up-to-date and relevant information in an easy-to-understand outline format for both students and residents. Basic scientific information is balanced by clinical relevance, and a wealth of more than 200 USMLE-formatted questions allows readers to test their knowledge prior to their board examinations.
