Prenatal hormonal theory

The neurobiology of the masculinization of the brain is fairly well understood. Estradiol and testosterone, which is catalyzed by the enzyme 5α-reductase into dihydrotestosterone, act upon androgen receptors in the brain to masculinize it. If there are few androgen receptors (people with androgen insensitivity syndrome

), there can be physical and psychological effects. It has been suggested that both male and female heterosexuality are results of variation in this process. In these studies heterosexuality in females is linked to a lower amount of masculinization than is found in lesbian females, though when dealing with male heterosexuality there are results supporting both higher and lower degrees of masculinization than homosexual males.

Heterosexual behaviors in animals

Most of the reproduction in the animal world is facilitated through heterosexual sex, although there are also animals that reproduce asexually, including protozoa and lower invertebrates.

Reproductive sex does not necessarily require a heterosexual orientation, since orientation refers to a long term enduring pattern of sexual and emotional attraction leading to often long term social bonding, while, reproductive sex requires only the basic act of, often one time, vaginal intercourse.

, have found that the majority of humans have had both heterosexual and homosexual experiences or sensations and are bisexual. Contemporary scientific research suggests that the majority of the human population is bisexual, adhering to a fluid sexual scale rather than a category, as Western society typically views sexual nature. However, social pressures influence people to adhere to morals, categories or labels rather than behave in a manner that more closely resembles their nature as suggested by this research.

Kinsey himself, along with current sex therapists, focused on the historicity and fluidity of sexual orientation. Kinsey's studies consistently found sexual orientation to be something that evolves in many directions over a person's lifetime; rarely, but not necessarily, including forming attractions to a new sex. Rarely do individuals radically reorient their sexualities rapidly—and still less do they do so volitionally—but often sexualities expand, shift, and absorb new elements over decades. For example, socially normative "age-appropriate" sexuality requires a shifting object of attraction (especially in the passage through adolescence). Contemporary queer theory

. The consensus of psychologists is that sexual orientation, in most individuals, is shaped at an early age and is not voluntarily changeable.

Other studies have disputed Kinsey's methodology. "His figures were undermined when it was revealed that he had disproportionately interviewed homosexuals and prisoners (many sex offenders)."

Sexologists have attributed discrepancies in some findings to negative societal attitudes towards a particular sexual orientation. For example, people may state different sexual orientations depending on whether their immediate social environment is public or private. Reluctance to disclose one's actual sexual orientation is often referred to as "being in the closet." Individuals capable of enjoyable sexual relations with both sexes or one sex may feel inclined to restrict themselves to heterosexual or homosexual relations in societies that stigmatize same-sex or opposite-sex relations. In traditional societies, individuals are often under heavy social pressure to marry and have children, irrespective of their desired sexual orientation.

Critique of studies

The studies performed in order to find the origin of sexual orientation have been criticized for being too limited in scope, mostly for focusing only on heterosexuality and homosexuality as two diametrically opposite poles with no orientation in between.

It is also asserted that scientific studies focus too much on the search for a biological explanation for sexual orientation, and not enough on the combined effects of both biology and psychology.

Social and historical

Since the 1960s and 1970s a large body of scholarship has provided evidence and analysis of the extent to which heterosexuality and homosexuality are socially organized and historically changing. This work challenges the assumption that heterosexuality, homosexuality, and sexualities of all varieties, can be understood as primarily biological and psychological phenomena.

In Genesis 2:24, which is considered scripture by Abrahamic religions, there is a commandment stating "Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh" In 1 Corinthians, part of the Christian Bible, Christians are advised:
