Are people born gay? Show more Show less

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?

No, people are not born gay Show more Show less

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.

Gay people have fewer offspring

The laws of evolution dictate that if sexual orientation was genetic, gay people would have died out already as they have far fewer offspring than heterosexuals.

Context

In order to be born gay, there would have to be something in our genetics that leads us to develop same-sex attraction. But gay people do not reproduce in large enough numbers to ensure the survival of the gene. Darwinian evolutionary principles suggest that if homosexuality was genetic, it would have died out long ago.

The Argument

Counter arguments

Not everyone that carries the gene has to be gay. It is highly possible that women can be carriers for a homosexuality gene and men could be carried for a lesbian gene. There was also a study carried out in Italy that revealed that female relatives of homosexuals have 1.3 times more children than the average female. This would explain why the number of gay people is not decreasing despite same-sex couples not having children. [1]
