I n a recent Guardian articleSimon Copland argued that it is very unlikely people are born gay or presumably any other sexual orientation. Scientific evidence says otherwise. It points strongly to a biological origin for our sexualities.
But geneticists have had only a handful of underpowered studies to address a complex, fraught, and often stigmatized area of human behavior. Now, the largest-ever study of the genetics of sexual orientation has revealed four genetic variants strongly associated with what the researchers call nonheterosexual behavior. Some geneticists are hailing the findings as a cautious but significant step in understanding the role of genes in sexuality.

As for the report itself, by analyzing studies into sexuality, gender identity, and the mental health of LGBT people, Mayer and McHugh have apparently determined that the concept of sexuality and gender identity being innate is not backed up by current scientific evidence.
Let friends in your social network know what you are reading about. Genes and hormones have an effect, but a growing chorus says the "born this way" narrative excludes people who experience sexuality as fluid rather than fixed.

Distinguished scholars at Johns Hopkins University in Maryland released a new page report on Monday that argues that there is not enough definitive scientific evidence available to suggest that gay, lesbian and transgender individuals are born with a certain sexual orientation or gender identity. Additionally, the scholars challenge the claim that discrimination and social stigma is the sole reason why those with same-sex attractions or transgender identity suffer higher rates of mental health problems. The report goes into detail about past epidemiological studies that have found a modest association between genetic factors and sexual orientation and behaviors.
In the Aug. In a large study of more thanmen and women in the United States, United Kingdom and Sweden, researchers discovered four genetic variants that occur more often in people who indicated on questionnaires that they had had same-sex sexual partners. The other two influence sex partner choice for both men and women.
By Andy Coghlan. Two gene variants have been found to be more common in gay men, adding to mounting evidence that sexual orientation is at least partly biologically determined. How does this change what we already knew?
Is sexuality purely the result of our biology? Brandon Ambrosino argues that simplistic explanations have ignored the fluid, shape-shifting nature of our desires. You so obviously cannot be gaywas her implication, because this is good sex. If you happened to engage in activity that ran counter to your sexual identity, then you had two options: you were lying to yourself and everyone else, or you were just experimenting.
The reasons behind why people are gay, straight or bisexual have long been a source of public fascination. Indeed, research on the topic of sexual orientation offers a powerful window into understanding human sexuality. Among the indigenous Zapotec people in southern Mexico, individuals who are biologically male and sexually attracted to men are known as muxes.
That amounts to an evolutionary paradox: gay men have fewer children, so one would expect that the trait would disappear over time. Now a team of researchers has carried out the largest-ever genetic study of sexual orientation and found evidence consistent with one possible explanation. Details of the unpublished study have been described in a public research plan, in two scientific abstracts, and by researchers at a scientific meeting held in June at the Broad Institute, a genome research center in Cambridge, Massachusetts.
