How do genes influence our sexuality? The question has long been fraught with controversy. An ambitious new study — the largest ever to analyze the genetics of same-sex sexual behavior — found that genetics does play a role, responsible for perhaps a third of the influence on whether someone has same-sex sex.
Sexual orientation is an enduring pattern of romantic or sexual attraction or a combination of these to persons of the opposite sex or genderthe same sex or gender, or to both sexes or more than one gender. These attractions are generally subsumed under heterosexualityhomosexualityand bisexuality  while asexuality the lack of sexual attraction to others is sometimes identified as the fourth category. These categories are aspects of the more nuanced nature of sexual identity and terminology.
The approach I took in my responsum for the Committee on Jewish Law and Standards of the Conservative movement in March adopted a biological argument for condoning homosexual sex. These, however, are only preliminary results, and the consensus of experts nowadays is that sexual orientation is a product of both nature and nurture. What was therefore more cogent for me in writing my opinion for the committee was the testimony of actual gays and lesbians, many of whom attest that being gay is not something they chose.
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.
I grew up in a Catholic household surrounded by a fair amount of straight men and straight women of varying ages, and spent an equal amount of time with both genders. I was the only gay kid was unaware at the time that I was for some years in elementary school, and had only straight male and female friends. The majority of my childhood relatives and friends with whom I spent a lot of time were boys.
Homosexuality is romantic attraction, sexual attractionor sexual behavior between members of the same sex or gender. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions. Along with bisexuality and heterosexualityhomosexuality is one of the three main categories of sexual orientation within the heterosexual—homosexual continuum.
By Marcia Malory Ask this question, and you will probably receive one of two responses:. People choose to be gay. They are making an immoral choice, which government should discourage.
The question of what causes some people to be gay has been a topic of endless debate among the general public and the mental health community. Generally speaking, the religious community of every persuasion views homosexuality as an abhorrent sin against God and nature. Deeply religious groups among Muslims, Christians, Catholics and Jews reject homosexuality as totally unacceptable in the eyes of God.
This book presents a simple description of the biological mechanisms that are involved in the determination of sexual orientation in animals and also presumably in humans. Using scientific studies published over the last few decades, it argues that sexual orientation, both homosexual and heterosexual, is under the control of embryonic endocrine and genetic phenomena in which there is little room for individual choice. The book begins with animal studies of the hormonal and neural mechanisms that control the so-called instinctive behaviors and analyzes how this animal work may potentially apply
Same-sex attraction refers to emotional, physical, or sexual attraction to a person of the same gender. The experience of same-sex attraction is not the same for everyone. Some people may feel exclusively attracted to the same gender, while others may feel attracted to both genders. The Church distinguishes between same-sex attraction and homosexual behavior.
