Organisation Intersex International from 2011 to 2017. They are the founding director of the
Intersex Campaign for Equality (formerly OII-USA) Viloria used female pronouns earlier in her life and activist career.
In May 2017, Meghan Daum reviewed Born Both
in The New York Times'', saying: "Viloria does us the even greater service (it's more of a gift, really) of showing us what it means to live not just as both a man and a woman but also as a
third gender that eventually emerges as the right one." Speaking on the
LGBTQ&A podcast in December 2021, Viloria said, "The reason I did my memoir is because I felt like there's a story that we don't hear enough of about intersex people, which is that it's amazing and wonderful to be intersex. That's literally my experience."
Born Both was nominated for a 2018
Lambda Literary Award for LGBTQ non-fiction.
Opposing nonconsensual medically unnecessary surgeries Viloria has been advocating publicly against the use of medically unnecessary cosmetic surgeries and hormone therapy on intersex infants and minors, also known as intersex genital mutilation, since 1997, reaching audiences of over one hundred million via appearances in various documentaries about intersex people, including the first
Hermaphrodites Speak!, and most notably on ABC's
20/20,
The Oprah Winfrey Show, and at the UN Headquarters in New York City for Human Rights Day 2013. In 2004, Viloria testified before the
San Francisco Human Rights Commission on the need to ban medically unnecessary cosmetic genital surgeries on intersex infants and children. Between 2010 and 2017 Viloria published numerous essays speaking out against nonconsensual medically unnecessary surgeries in publications including CNN.com,
The Advocate,
The Huffingtion Post, and the
Narrative Inquiry in Bioethics.
Opposing "disorders of sex development" In 2006, the international medical establishment replaced the terms "hermaphrodite" and "intersex" with the term "
disorders of sex development". In 2007, Viloria publicly critiqued the label and the homophobic and transphobic reasoning behind the replacement of 'intersex' with DSD. They also argued that being raised to define oneself as disordered is psychologically harmful to intersex youth.
Addressing discrimination against intersex women in sports Viloria argued in 2009, on television and in print that Olympic sex testing is applied in a way that targets 'butch,' or masculine-looking, women. In February 2010, then as Human Rights Spokesperson of the
Organisation Intersex International (OII), they authored a petition to the International Olympic Committee demanding that intersex women athletes to be allowed to compete as is, and be de-pathologized. The action resulted in Viloria being invited to participate in the
International Olympic Committee's October 2010 meeting of experts on intersex women in sports, in
Lausanne, Switzerland. In 2012, Viloria co-authored an article in the
American Journal of Bioethics, with intersex Spanish hurdler
Maria José Martínez-Patiño, the athlete responsible for overturning the
IOC's long-standing mandatory chromosome testing policies, which critiqued the IOC's proposed regulations for women with high levels of naturally occurring testosterone (aka hyperandrogenism). They also collaborated on an opinion piece with scholar
Georgiann Davis and also told
The New York Times that the issues for intersex athletes remain unresolved: "Many athletes have medical differences that give them a competitive edge but are not asked to have medical interventions to 'remove' the advantage.... The real issue is not fairness, but that certain athletes are not accepted as real women because of their appearance."
Birth registrations In April 2017, Viloria became the second American recipient of an intersex birth certificate, issued by the city of New York.
National and global affiliations and activism In spring 2010, Viloria joined the
Organisation Intersex International (OII), the first international intersex organization, was appointed Human Rights Spokesperson, and began lobbying against discriminatory regulations for intersex women athletes. In spring 2011, Viloria was voted Chairperson of OII, upon founder Curtis Hinkle's retirement. Viloria stepped down in November 2017, when Intersex Campaign for Equality left OII. In 2012, as OII Chairperson, Viloria spearheaded the first unified, global call for human rights by and for intersex people, in a letter signed by thirty leading intersex advocacy organizations, to the
Office of the United Nations High Commissioner for Human Rights. On
Human Rights Day, 2013, Viloria became the first openly intersex person to speak at the U.N., by invitation, at the event "Sport Comes Out Against Homophobia", along with fellow "out" pioneers, tennis legend
Martina Navratilova, and
NBA player
Jason Collins.
Media Viloria spoke about being
intersex and
genderqueer in the award-winning 1999 documentary
Gendernauts. In 2002, Viloria spoke about feeling blessed they did not experience forced infant genital surgeries on
20/20. In 2007, on
The Oprah Winfrey Show, Viloria likened society's lack of understanding of intersex people, and the pressure intersex people experience to identify as men or women, to what people of mixed African-American and Caucasian race sometimes experience, saying, "Society pressures you to choose sides, just like they pressure
mixed race people to decide, you know... 'Are you really black? Are you really white?'" Viloria went on to say "I have both [sides]". In September 2015, the UN's Free & Equal Campaign for Equality produced a video of Viloria in conjunction with the release of their groundbreaking resource the Intersex Fact Sheet, and in 2016 Viloria was one of the "Intersex Voices" featured in the Free and Equal Campaign for Equality's Intersex Awareness Campaign. Viloria has also advocated against intersex genital mutilation via essays, and in their 2017 memoir,
Born Both: An Intersex Life. In 2019 Viloria was featured in the
Smithsonian Channel documentary, "
The General Was Female?", which explores compelling evidence that General
Casimir Pulaski, revered as the father of the American Cavalry, may have been intersex. == Selected bibliography ==
