Current Opinion in Obstetrics and Gynecology was launched in 1989. It is one of a successful series of review journals whose unique format is designed to provide a systematic and critical assessment of the literature as presented in the many primary journals. The field of obstetrics and gynecology is divided into ten sections that are reviewed once a year. Each section is assigned one or more Section Editors. They are the leading authorities in their area, who identify the most important topics at that time. Here we are pleased to introduce the Journal's Section Editors for this issue.
