Problems of intersex people in India are seen as problems of third gender people. The most well-known third gender groups in India are the "hijras". After talking to "hijras" for many years, Serena Nanda wrote a book called "Neither Man Nor Woman: The hijras of India". In the book, she wrote that people in India believed that hijras were born as intersex persons and were taken away by the hijra community at birth or in childhood. However, she found no proof for this belief among the hijras whom she met. They had all joined the group on their own whenthey were teenagers. Sangam literature uses the word "pedi" for people who are born intersex. Other groups in India call intersex people as "mabedi usili" and give them special names.
