Changing and Unchanging Perspectives regarding Intersex in the Last Half Century: Topics Presented in the Lawson Wilkins Lecture* at the 2015 Pediatric Endocrine Society Meeting.

The understanding, care and treatment of patients born with intersex or disorders of sex development conditions has evolved considerably over the last five decades. Regarding those who require evaluation before gender assignment is made, each "generation" of approach has been based upon and reflects the contemporary biological, social and psychological understanding. The most recent generation needs to consider the dramatically changed societal viewpoints regarding the acceptance and expansion beyond a binary perception of sexuality. This together with advances in genetic etiologies, surgical refinements and psychological support should result in better care and quality of life (QoL) outcomes for patients with these conditions. This paper reviews the successive generations of approach and discusses the multiple challenges facing the multidisciplinary teams caring for these patients today.
