How Do People Become Gay?

As of today’s date this post will be valid until further research has been identified to prove otherwise. While most people believe you are born gay, others believe it is because of trauma or lack of love from the same sex that causes someone to be gay.

Please be mindful that this article was written by me for my professor during a PhD program in Health Psychology. Further data and research will serve in a more profound exploration as scientist continue to explore what scientist, philosophers, and researchers call a phenomenon.

For those of you with pending questions, here is science for you.

Article Summary 

The understanding of a phenomenon leaves data to speak of its truths, and by the same token may leave research with more to explore. The article chosen speaks of androgen as being a common composer to women being attracted to women, thus leading to a woman being a lesbian.  Men, on the other hand, have no common denominator as to how a man can become gay or whether they are gay from birth.

The meta-analysis sexual orientation difference study and research conducted indicates that lesbians were exposed to a larger amount of androgen than were straight women during the time they were developing in the womb. In addition, an even larger amount of prenatal androgen was exposed to fetal males. The article continues to clarify that this may be of greater understanding of why the majority of men are attracted to women (Breedlove, S.M. 2016).

Two Implications 

The two implications that the article explores is that of androgen being a common theme in research towards understating the development of sexual orientation in the womb for women, and, although gay men were exposed to the same amount of androgen as straight men, it still leaves the question as to what leads to sexual orientation during prenatal exposures for men (Yin, Norton, and Rahman, (2017). The second implication being prenatal and postnatal exposures and how they may contribute to orientational findings (Breedlove, S.M. 2016).

These two implications were explored to bring clarity to this phenomenon. ‘Gay men were sex-atypical in both male and female cognitive performance.’ In addition, homosexual women were sex-atypical only in favoring male cognitive traits and performances (Yin, Norton, and Rahman, (2017).

Concur or Conflict 

In reviewing multiple articles, a 1997 article reflected it’s truth by stating that there is “Too little known about the biology of the homosexual type for this research. Also, the weight of evidence suggests perinatal sexual differentiation as a developmental component in the sexual orientation of at least some homosexual men (McKnight, 1997).” The meta-analysis revealed that homosexual men performed like heterosexual women in both male-favoring (Yin, Norton, and Rahman, (2017). Hormonal studies were still being conducted during the time nor to bring understanding. 

In another 2017 study conducted by Burke, Manzouri, and Savic (2017), long white matter, water diffusion along the axon, and research conducted on parts of the brain’s anatomy (e.g. right inferior frontal-occipital tract, corticospinal tract, corpus callosum etc.) were all processed. In each article, there is one question that still remains unanswered.

One Question Remains

Can sexual orientation be understood by science? Or can science really make sense of sexual orientation or even create further distinctions between two entities within sexual orientation? Or is the question really, can science make sense of how and when is sexual orientation truly developed? The underlying mechanism is considered and classified as unrevealed (Burke, Manzouri, and Savic, 2017).

What has been identified is the neurobiological hallmark between the neurobiological connections the body holds in the connection of the self and the perception of self, as well as body ownership. This too is a continual exploration of homosexuality among the transgender population as well (Burke, Manzouri, and Savic, 2017). 

Further studies will have to be explored. Does homosexuality begin in the stages of prenatal exposure or in postnatal experiences and exposure? Does it depend on these two facets? There are many unanswered questions, yet all are looking for evidence of possible truths to bring this hunger for clarity to rest.
