Polycystic ovary syndrome: consider the entire spectrum

Two relatively recently published articles consolidate our existing knowledge about polycystic ovary syndrome (PCOS) and reinforce the notion that this syndrome has been characterized historically by multiple etiologies presented by complex and variable patient populations. The first comprehensively reviewed the history of research studies in PCOS (1). The second provided carefully updated evidence-based guidelines for the assessment and management of PCOS that expanded recommendations from several earlier consensus conferences and an earlier guideline, with all the taskforces supported in part by the American Society for Reproductive Medicine (2).
