In 1991, the journal Science published a report on the hypothalamus by another scientist, who was also gay, Simon LeVay. He found another nucleus of the hypothalamus (INAH 3) that was larger in heterosexual men than in women or homosexuals. Laura Allen, a professor of anatomy at the University of California, Los Angeles, in 1992, discovered another area of the brain that differed in size between men and women. This was called the Anterior Commissure, a group of cells attached to the hypothalamus that connected to the temporal lobes. Allen said that her study suggested that “the entire brain is organized differently in gay men in this region, and not just in one area that affects sexual behavior.” The implication was that gays were physically and behaviorally, women.
These findings sought chemical components that influenced sexual orientation during pregnancy, so the supposed “corrective therapy” was the control of hormonal flows.
However, other recent studies questioned all these works and found no differences in the brains of homosexuals and heterosexuals.
In 1993, the journal Science published an article claiming to have discovered genetic markers at the tip of the X chromosome that influenced homosexual orientation in men. However, this has not been found in most homosexuals.
Today, ideas about homosexuality have evolved significantly from historical beliefs and misconceptions.
