We recognise the medical factors and scientific developments and social issues that have led people to seek to develop a new terminology for intersex; but we also understand that intersex is part of human diversity and support Milton Diamond in his call to use "variation" instead of "disorder". We regard the term "Variations of Sex Differentiation" (VSD) as more accurate than using "Disorder of Sex Development" (DSD) because it describes a biological phenomenon as a variation, rather than as a disordered state. Disorder can have emotive and pejorative connotations, especially when misused to categorize a group of people.
"Disorder" may work as a medical descriptor, but because most intersex conditions present a range of symptoms, beyond just ambiguous genitalia, using "Disorder" and "Sex/Sexual" puts the focus primarily on sexual characteristics. The schema offered by the consortium appears inconsistent: at times DSD is used in relation to probable genetic causes regardless of symptoms, at others symptoms alone are described as DSD; those symptoms are discounted as DSD where they are not severe enough and there is no known underlying cause. "Variation" puts the focus on a range of underlying causes, symptoms and expressions, and avoids the arbitrariness clearly evident in the taxonomy produced by the consortium.
"DSD" represents a model of "disordered sex", as in "disordered male" or "disordered female"; it is this model which has been implemented in an arbitrary manner in the past (as in male/female pseudohermaphrodite). "VSD" does not focus on a "disordered sex" view of the individual patient, is more open and inclusive, and allows for a precise and flexible approach which can avoid arbitrary definitions; this would enable underlying causes and secondary symptoms to be better described in a way that does not represent the patient as deficient or defective in some way.
Organisation Intersex International is the only international and multilingual intersex activist group, having members from around the world. In a recent internet survey we found that 90% of respondents disliked the term "disorder", many intersex people themselves preferred to retain the term "intersex", or use terms like "variation" and "VSD".
We support Eric Vilain in much of what he has said in your article, and welcome the way he has utilized so much of what intersex people have been saying to him over the past twenty years, but we cannot support the use of "disorder(s)" to refer to intersex. We have more detailed criticisms of the consensus statement itself, but there is insufficient space in a letter here. To date OII board-members have been denied any opportunity to discuss this international consensus with those who have formulated it; instead, intersex representation has been dominated by one advocacy group from the USA.
