Gay genes determine identity say scientists

Well, it's no surprise to me of course. I've always been gay, and I've known that since I was six years old. I didn't know what "gay" was then, but I knew that I was different from most other boys.

It's always surprised me that there's been all this speculation from people on what makes a person gay vs. straight. There have been many scientific studies performed (some not so nice to the subjects) to determine if it was a learned trait. More recently, there have been experiments and research performed to find the "gay gene".

I don't know if there is a "gay gene", but the thought that people are so bothered by someone being gay that they would actually look for the cause of them being gay, is scary. What do they hope to do with this information? I have one thought. If they can determine that a child has a good chance of being gay prior to birth through gene testing, it might be used as an excuse to abort that life. Pretty scary stuff.

The funny thing is that I could have saved them all a lot of work if they had just asked me if I was born gay. I would have said, "of course". I don't recall any time in my life making a decision on what sex to love. Do you? It was always a clear decision for me. I suppose it makes too much sense to ask a gay person those questions though.

Most people don't want to hear that. If a gay person says they are born gay, it will look as though they are trying to further the "gay agenda", whatever that is. If it is shown that being gay is genetically determined, it makes it a bit harder for a civilized society to justify the poor treatment homosexuals receive.

This is from a Reuters story I picked up off the internet:

Sexual identity is wired into the genes, which discounts the concept that homosexuality and transgender sexuality are a choice.

“Our findings may help answer an important question - why do we feel male or female?" Dr Eric Vilain, a genetics professor at the University of California, Los Angeles School of Medicine, said in a statement on Monday.

"Sexual identity is rooted in every person's biology before birth and springs from a variation in our individual genome," Vilain said.

His team has identified 54 genes in mice that may explain why male and female brains look and function differently.

Specific role

The scientists plan to conduct further studies to determine the specific role for each of the 54 genes they identified.

"Our findings may explain why we feel male or female, regardless of our actual anatomy," said Vilain. "These discoveries lend credence to the idea that being transgender - feeling that one has been born into the body of the wrong sex - is a state of mind.

Since the 1970s, scientists have believed that estrogen and testosterone were wholly responsible for sexually organising the brain. Recent evidence, however, indicates that hormones cannot explain everything about the sexual differences between male and female brains.

Published in the latest edition of the journal Molecular Brain Research, the UCLA discovery may also offer physicians an improved tool for gender assignment of babies born with ambiguous genitalia.

Mild cases of malformed genitalia occur in 1% of all births - about three million cases. More severe cases - where doctors cannot inform parents whether they had a boy or girl - occur in one in 3000 births.

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

Using two genetic testing methods, the researchers compared the production of genes in male and female brains in embryonic mice - long before the animals developed sex organs.

They found 54 genes produced in different amounts in male and female mouse brains, prior to hormonal influence. 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.
