Adolescent sexuality and gynecologic care of young patients are topics which make most clinicians uncomfortable. This is due to a lack of knowledge and training in many circumstances. Assumptions based upon knowledge of adult gynecology alone may be hazardous for pediatric and adolescent patients. These children and young women often do not have access to specialists who are able and willing to care for their gynecologic issues at an appropriate level. The primary care setting is often the most comfortable venue for a number of these patients. The concept for this book was to provide a reference for primary care providers without highly specialized gynecology textbooks, just to focus on what providers tackle on a daily basis. The first edition was well received and the feedback was good. In the 10 years since the first edition was published, our knowledge has improved and many new methods, medications and devices were added to daily practice. Those changes prompted the Editors to provide an updated version of the book, while keeping its essence intact.
