About transsexuals and transgenders, an article was written about it by the Watchtower Bible and Tract Society, but was never published. However, several Jehovah’s Witnesses in position of authority are aware of it. For example, an individual who has changed sex and wishes to become a Jehovah’s Witness will necessarily have to return to the sexual identity he or she had at birth, although he or she will not be asked to undergo surgery again. Regarding the intersex people (hermaphrodites), the Watchtower said that there is usually a dominant sex and it does not require that they undergo surgery.
