New Gay Gene Evidence

(Los Angeles, California) Evidence continues to mount that sexuality is genetically controlled. The latest findings were reported today by researchers from the University of California.

The scientists, in a statement, said that sexual identity is "hard-wired" into the genes.

"Sexual identity is rooted in every person's biology before birth and springs from a variation in our individual genome," said Dr. Eric Vilain, a genetics professor at the UCLA School of Medicine.

Vilain and his team of researchers have identified 54 genes in mice that may explain why male and female brains look and function differently. They used two separate genetic testing methods to compare the production of genes in male and female brains in embryonic mice -- long before the animals developed sex organs.

They discovered 54 genes produced in different amounts in male and female mouse brains. Eighteen of the genes were produced at higher levels in the male brains; 36 were produced at higher levels in the female brains.

"We discovered that the male and female brains differed in many measurable ways, including anatomy and function." Vilain said. Among the differences, the two hemispheres of the brain appeared more symmetrical in females than in males. According to Vilain, the symmetry may improve communication between both sides of the brain, leading to enhanced verbal expressiveness in females.

Vilian warns though that finding the exact gene that results in homosexuality will require considerable more research. He said that if future research does determine conclusively that homosexuality is genetic and not a choice, the implications would be huge.

"If it's not a choice, you can't have the typical conservative argument that says you choose this lifestyle so you have to bear the consequences and society has no reason to basically give you any rights because you choose to be an outcast," Vilain said.

"If you can't do anything about it, therefore you should have all the rights to be integrated into society and have the same rights as heterosexuals in terms of marriage and the rights to inheritance."

Vilain said the initial emphasis will be on determining the origin of transgenderism. He says the research may help doctors determine the proper gender assignment of babies born with ambiguous genitalia.

"If physicians could predict the gender of newborns with ambiguous genitalia at birth, we would make less mistakes in gender assignment," Vilain said.

Typically such a baby is assigned a gender and in many places in North America genital surgery is performed to make the genitals appear to conform to the gender selected.

But many grow up very unhappy, feeling the surgery was harmful by assigning them a gender they didn't feel was appropriate.

The Human Rights Campaign welcomed the results but said that laws should protect all Americans equally, regardless of the genetic basis for being gay, lesbian, bisexual or transgender.

"This study is part of a growing body of evidence showing that it is likely that sexual orientation and gender identity are genetically based," said Elizabeth Birch, HRC's executive director.

"Although further research will be conducted by this team, at the end of the day, the question of nature versus nurture shouldn't matter. Laws in America should protect everybody equally, regardless of what causes differences of sexual orientation or gender identity."

Last week, British psychologists also said they have found strong evidence to support the theory that a person's sexuality is "hard-wired" into the brain before birth. (story)
