Childhood sexual abuse is well attested to demonstrate a correlation to the incidence of homosexuality among those affected by it. A large national survey of almost 35,000 Americans showed that more three times as many men and women who had been sexually abused as children became homosexuals versus that of heterosexuals.<ref>7.4 percent or homosexual men and 3.1 percent of females, versus 2.0 percent  of heterosexual men and 0.8 percent women.</ref><ref>Laumann, Gagnon, Michael, and Michaels, ''The social organization of homosexuality:...'', (1994) p. 344</ref>  Another study reported that 58 percent of male adolescents who later became homosexuals suffered sexual abuse as children, while 90 percent who did not suffer sexual abuse identified themselves as heterosexuals.<ref>Sheir and Johnson, ''Sexual victimization of boys:...

==Biological research on the causes of homosexuality ==

The idea that homosexuality has a biological cause can be traced back to the preliminary findings of neuroscientist Dr. Simon LeVay in 1991. LeVay's studied the brains of 41 cadavers, which included 19 homosexual males, and claimed that "a tiny area believed to control sexual activity [the hypothalamus] was less than half the size in the gay men than in the heterosexuals."<ref>Charlene Crabb, ''Are Some Men Born to Be Homosexual?'', U. S. News & World Report, 9 September 1991, p. 58</ref><ref>S. LeVay, "A Difference in Hypothalamic Structure Between heterosexual and Homosexual Men," Science 253 (1991), pp. 1034-37</ref>  This study was immediately seized upon by many as  proof that homosexuality was biologically determined.

However, further scrutiny showed their hasty conclusions a critically lacking warrant.
