There is no scientific research indicating a biological or genetic cause for homosexuality. Biological factors may play a role in the predisposition to homosexuality. However, this is true of many other psychological conditions.
Research suggests that social and psychological factors are strongly influential.
Examples include problems in early family relationships, sexual seduction, and sense of inadequacy with same-sex peers, with resulting disturbance in gender identity. Society can also influence a sexually questioning youth when it encourages gay self-labeling. Therefore, treatment to change homosexuality must be stopped. Psychotherapists around the world who treat homosexuals report that significant numbers of their clients have experienced substantial healing. Change has come through psychological therapy, spirituality, and ex-gay support groups.
