Few scientific questions generate as much intrigue and political turmoil as the origins of sexual orientation. Is there a clear genetic or hormonal link to sexual orientation that indicates gay people are, in the words of Lady Gaga, "Born This Way"? Can we ever know if same-sex attraction is determined before birth? Is this a question that should even be asked?
Various studies have found a direct link between genetics and homosexuality.
The argument from epigenetics
The same genetic code can be expressed differently depending on chemical changes that take place before birth.Explore
Xq28 is the gay gene
Scientists have been able to trace same-sex attraction to a single gene, Xq28.Explore
The fraternal birth effect
The more older brothers you have, the higher the likelihood of you being attracted to members of the same sex.Explore
Neurological differences between gay and straight people
Gay people have a different neurological structure to their heterosexual peers.Explore
Homosexuality is a genetic trait that runs throughout generations
Homosexuality is a genetic trait passed from parents to children. The gene continues to spread throughout generations. The extended families of homosexuals tend to have multiple family members attracted to members of the same sex.Explore
We can't choose our sexual orientation because it's genetically inherent
We have a stake in our own development through free will and existential choice. If we can't choose our sexuality, it must be innate rather than developed. Genetics and physical development can't be changed.Explore
No, people are not born gay
To reduce sexual orientation to genetics or hormones reduces it to a binary outcome. Sexuality is not binary, it is fluid and no genetic explanation has been able to accomodate this.
Sexual orientation is not a binary outcome
Only things with binary outcomes can be reduced to genetics. Sexual orientation is not binary, it is fluid.Explore
Gay people have fewer offspring because of the genetics they pass on
The laws of evolution dictate that if sexual orientation was genetic, gay people would have died out. The genetics that they carry affects their children. If their children have the same genetics that make them gay, they have far fewer offspring than heterosexuals.Explore
Identical twins can have different sexual orientations due to environment
Two identical twins that share the same genetics can have different sexual orientations. Identical twins don’t have the exact same mindset. Therefore, it’s environment that chooses sexuality.Explore
Same-sex attraction is a mental illness that needs professional treatment
Mental illnesses are developed or innate. Homosexuality is a psychological condition caused by an underlying mental illness. Instead of being an orientation, it needs to be treated by a doctor.Explore
We don't know if people are born gay
No conclusive evidence has been found to settle the debate.
The word is still out on genetics
Although numerous studies have been conducted, none have come to a definitive conclusion. Between small data sets and conflicting results, the current studies show no conclusive evidence.Explore
Is the word "gay" a concrete concept with a clear definition of a sexuality?
The terms "gay", "straight" and "bisexual" don't have clear meanings. People change their sexuality and even "experiment" with relationships outside of their sexual preference. If we can't define the terms, how can we trace their origins?Explore
It doesn't matter if people are born gay
The question of whether people are born gay is unimportant and could be dangerous.
We are better off not knowing
The answer to the question will only have negative repercussions for the LGBTQ+ community.Explore
You shouldn't get to define someone else’s homosexuality
The reasons someone is gay are highly personal. Nobody should be allowed to tell someone else why they are gay.Explore
