Is Homosexuality Biologically Based
An individual’s sexual positioning is their unambiguous perpetual preference starting from sexual maturity when other substitutions are available (Silfe, 2012). Persons have their own sexual preference they choose to be with, no one is born to like the same sex. An indisputable fact about humanity is that every individual owes their existence to the physical union between their father and mother, and this reality forms the basis for the concept of family.
However, anthropologists clearly point out that the existence of homosexuality has been identified in some societies at different degrees of prevalence throughout the history. The trait of homosexuality can be simply defined as the sexual attraction between the individuals of the same sex. A homosexual person in the male gender is called ‘gay’ while the term ‘lesbian’ represents a homosexual female. Over the past three decades, the number of homosexuals has dramatically increased and such trait has increasingly grown to be mainstream and open.
Several studies suggest alterations association prenatal exposure to androgens or estrogens. One study reports that some women are exposed to high levels of androgens during development (adolescence) because of development with other endocrine disorder is to self-report a bisexual or homosexual orientation, (Money et al. , 1984) The current debate is whether or not homosexuality is a result of nature: a person’s environment and surroundings, or of his biology and genetics.
The debate endures because both sides have the ability to create a scientific environment to support their cause. For example, biological theorists may argue that a monkey and human child, reared in the same setting, will develop with vastly different outcomes, while social theorists may argue that monozygotic twins, one reared normally and the other raised in seclusion for 18 years, will also develop with vastly different results, but different even more from the first scenario. Sex hormone levels were found to be normal in the majority of homosexual women, but prenatal androgen excess, heterosexuality appears to be more frequent than bisexuality, an exclusive homosexuality is rare. … Contrariwise, the removal of the adrenal, which is the major androgen-producing organ in the female, decreases libido.
These findings have led to the hypothesis that androgens are the libido hormone in women as well as in men. We can conclude hat the majority of female homosexuals appear to have testosterone and estrogen levels within normal female range, whereas there seems to be a significant subsection of about one-third of all subjects screened with an elevation of male sex hormone levels. ” (Meyer-Bahlburg, H. (1979) “Women exposed prenatally via their pregnant mothers to diethylstilbestrol estrogen with masculinizing effects in female mammals) received higher ratings of homosexual behavior (Ehrhardt et al. , 1985) and showed an increased incidence of left-hand preference compared to female controls.
Similarly, women with congenital adrenal hyperplasmia compared to female controls. In summary, there appears to be an association, at least in women, among excessive prenatal exposure to masculinizing hormones, homosexual behavior, and increased left-hand preference. Researchers are still only beginning to comprehend the genetic causes of homosexuality. Studies conducted to date, it is evident that biology is the largest aspect in determining a person’s sexual identity and preference, Studies in the fields of psychology still being researched.
