How Older Brothers Influence Homosexuality
Homosexuals are not Born Gay: Evidence from Science and History
Can someone really be "born" gay? Is there a "gay gene"? Does biology equal destiny? Clearly, the controversy over this issue is huge in our culture. While pro-gay activists and their allies want us to believe people are "born gay" and that sexual orientation is an unchangeable characteristic like race or eye color, a closer examination of the scientific evidence reveals that the "nature vs. In fact, since the early s, numerous studies attempting to establish a genetic cause for homosexuality have not proven to be valid or repeatable -- two important requirements for study results to become accepted as fact in the scientific community. Because of this, the current thinking in the scientific community is that homosexuality is likely caused by a complex interaction of psychosocial, environmental and possible biological factors.
Why Are People Gay? Gay By Choice or Is Being Gay Genetic?
Estimates and variance for the lesbian , gay and bisexual LGB population are subject to controversy and debate. Obtaining precise numbers on demographics of sexual orientation is difficult for a variety of reasons, including the nature of the research questions. Most of the studies on sexual orientation rely on self-report data, which poses challenges to researchers inquiring into the sensitive subject matter. More importantly, the studies tend to pose two sets of questions.
Few aspects of human biology are as complex—or politically fraught—as sexual orientation. Now, a new study claims to dispel the notion that a single gene or handful of genes make a person prone to same-sex behavior. The analysis, which examined the genomes of nearly half a million men and women, found that although genetics are certainly involved in who people choose to have sex with, there are no specific genetic predictors. Yet some researchers question whether the analysis, which looked at genes associated with sexual activity rather than attraction, can draw any real conclusions about sexual orientation. The handful of genetic studies conducted in the past few decades have looked at only a few hundred individuals at most—and almost exclusively men.
