The success of the conference was helped in part by the endorsement of the Endocrine Society and was jointly sponsored by the University of Miami Miller SchoolofMedicine. The history of this meeting dates back to 2004 when Dr. Maria New organized the1stworldconferenceinArizona.Theconferencebroughttogetherworldexperts inthefieldofdisordersofsexualdifferentiationandallowedthemtosharetheirvast amountsofknowledgeandcutting-edgeresearchwitheachother.Itwasalsoaway tobringthesescientiststoasingleroomwhereideasandtheoriescouldbediscussed aswellasnewcollaborations.Theconferencewasagreatsuccessandcouldbeseen intheliteraturebythesurgeofpeer-reviewedpapersandcollaborationsaroundthe world.Eventhoughdisordersofsexualdifferentiationhavebeennotedthroughout history, dating over 2,000 years, little was known and discoveries were waiting to happen.Dr.Newwouldhavelovedtohavethemeetingonanannualbasisbutwas unabletountilnow.

The large scale of the meeting became greatly apparent when the International Olympic Committee (IOC) not only expressed that they would like to be present at the meeting but also desired to sit with the experts at the meeting and discuss future testing regulations that would help avoid attention such as that seen by the South African runner. A roundtable discussion was further organized by Dr. New so that the experts, with their vast knowledge of gender issues, could advise the IOCaswellastheIAFF(InternationalAssociationofAthleticsFederation)onhow to determine an athlete’s eligibility by using better testing modalities as well as clearer definitions of what it means to be a male as well as a female. It was also important to express that there are times where a situation will shift from being a sportingissuetoamedicalissue.TheIOC,10yearsago,hadabolishedmandatory gendertestingbutwithrecentattacksonathletesquestioningtheirgenderinavery public manner, it has become apparent that a review of current guidelines and the needforthedevelopmentofnewguidelinesareneeded.Theroundtablediscussion encompassedboththescienceandtheethicsofthisdilemmaandhelpedclarifythe medicalaspectoftheseissues. Thescopeofthemeetingwentwellbeyondjustthesciencebehindmanyofthese disorders; it also dealt with many issues that are beneficial to the practitioner. Sex determination in newborns born with genital ambiguity can be found dating back morethan2,000years(ANCIENTHISTOFCAH).Itcanbefoundintheartand writings throughout time and across many cultures. But, even though it has been dealt with in all societies for over a millennium, an accurate and effective way to quickly diagnose and assign gender to these newborns is still under investigation.
