is being gay a choice or genetically predetermined?

Answer 1

The current thought on the issue (the presiding theory, outside of fundamentalist circles) is that a certain percentage of women have an allergy to the hormone that is produced in in the womb that serves to masculinize a fetus. All fetuses (feti?) start out as female, but at a certain point in development, hormones are released that masculinize the fetus if the XY chromosome is present. As mothers with this allergy have more children, their body builds up defenses against the allergen, essentially blocking it from being produced or transported into the womb. Thus Male fetuses are not properly "masculinized" leading to more feminine behavior, and typically female patterns of attraction. This is why the further down you are on the birth order, the more likely you are to be homosexual.

Answer 2

Genetics

Answer 3

It's no genetic, but it's not something you can choose either.
Boys need a father figure, that's genetic! Whena boy has a distant father, and an overbaring mother, the boy just doesn't get that father figure he needs so much.

By the time the buy reaches puberty, the boy will be attracted to other boys.

I'm gay, I don't think you are born gay. I things you just can't do anything about when you are a boy end up making gay by the time you are a teen.
I don't think I was ever given the choice to like guys or girls, but I don't think I was born gay.

Answer 4

Scientific researchers who specialize in human sexuality have shown that homosexuality is linked to biology and genetics.

An October 2004 scientific research publication stated that scientists at the University of Padua have found that women tend to have more children when they inherit the same genetic factors linked to homosexuality in men. This fertility boost more than compensates for the lack of offspring fathered by gay men, and keeps the “gay” genetic factors in circulation.

A study published in Human Genetics in February 2006 examined X chromosome inactivation in mothers of gay sons and mothers whose sons were not gay. Researchers found extreme differences between women who had gay sons and women who did not.

Another scientific study said that researchers have known for years that a man's likelihood of being gay rises with the number of older biological brothers, but the new study found that the so-called "fraternal birth order effect" persists even if gay men were raised away from their biological families. Anthony F. Bogaert, Ph.D., professor at Brock University, said "The research suggests that the development of sexual orientation is influenced before birth."

The older-brother effect was constant regardless of whether the men were raised with natural, adopted or stepbrothers. It also didn't matter if they weren't raised with their biological mothers. If gay younger brothers and older brothers don't have the same home environments, what do they have in common? "They shared the same uterus, the same womb, the same mother," Bogaert said.

Answer 5

Genetic.

Answer 6

its predetermined..even genetic..i know many females and males in my family had what they call urges but they all fought the urge and lived hetero sexual lives but until I came along they admire and fear my courage to stand up against everything they have been taught to follow..several females in my family only got married had kids but lived miserably because they denied a part of themselves...they tell me of how they loved someone in their past and even when they lived hetero lives they never forgot the lovers of their past..
to see me live this life now and pave the road for future members of my family who will follow its a good feeling..so for me its predetermined and sure as heck genetic..

Answer 7

Any sexual orientation is predetermined. We do not choose to be attracted to anyone. When we meet someone we simply find them attractive or not, no grand choice, no debating the pros and cons of it in your head, just being.

Answer 8

Genetic....there has been a difference genetically within the size and stature of the body and brain between gay individuals and straight individuals:)

Answer 9

It is NOT a choice. You are born the way you are... gay/straight, whatever it may be. Having a distant father and overbearing mother has no more play on whether you are gay or not than what your mother ate during her pregnancy with you.

Answer 10

biological and chemical differences in the brain,but maye genetic as well,but not a choice
