Have you ever wondered why people end up being homosexuals? What truly causes homosexuality? Is it something that has to do with the brain function or is it inborn (natural)? Are there factors that affects one’s sexual orientation? These are questions that beg an answer.

Type of sexual orientation

Apparently, there are two main types of sexual orientation: heterosexual and homosexual beings. Heterosexual beings are those people who are attracted to the opposite sex. On the other hand, homosexual beings are people that are attracted to the same sex — they are often referred to as “Gays”.

What truly causes homosexuality

According to popular opinions, a person may posses strong homosexual desires as a result of  i.e. family peculiarity, environment or cultural influence, peer pressure, early homosexual experience, repeated sexual activity and biological factors. See this article for more details here.

Biological factors

Many researchers believe that sexual orientation is determined by how the oddity in the structure of the brain was developed . However, there has been considerable debate whether homosexuality is an inherited tendency. Presently, there is no clear evidence that there something in the brain that make people homosexuals or gays.

As a matter of fact, a recent study shows that brain images of a homosexual person contain similar structure and functionality as of the heterosexual beings. This confirms that being a homosexual has no difference in terms of brain scans and images.

Another school of thought says: gay men possess feminine characteristics before they were born. Again, there are no scientific evidence to back up this claim, on that note, should be shoved aside.

Ray Blanchard, a professor of psychiatry at the University of Toronto, said  that the reason how someone could end up a Gay could be as a result of a mother’s body mounting an immune attack on her unborn son’s fetus. These were his words:

Male fetuses carry male-specific proteins on their Y chromosome, called H-Y antigens. Blanchard hypothesized that some of these antigens promote the development of heterosexual orientation in males … Because these H-Y antigens are not present in the mother’s body, they trigger the production of maternal antibodies. These antibodies bind to the H-Y antigens and prevent them from functioning


In other words, if the Y chromosome is damaged, the unborn son could result to being homosexual due to the fact that, the heterosexual signal in the fetus brain doesn’t function as it should.  Ray’s research is still ongoing and until proven, many people think this is just a mere conjecture.

Evidently, there are no provable biological causes of homosexuality, however, there is a strong evidence that the tendency to posses strong homosexual desires is learnt from social and environmental influences — according to a report conducted by Kinsey in 1940s.

The table below is the result of a study conducted by Family Research Institute (FRI), involving 147  homosexuals and 3,400 heterosexuals concerning their sexual preference. These results are in no way conclusive.


From the result we can see that homosexuality is a behavior that is a learned due to the occurrence of certain events. One very important things to note here is; only 9% of homosexuals believe they were born that way.

Mental illness

Many believe that homosexuality is a mental disease. According to Irving Bieber and Charles Socarides, homosexual behavior is a mental illness resulting from early childhood and other traumatic experiences. While i was researching this subtopic, i found the evolution of homosexuality very interesting. Perhaps you may find the information that follows interesting too.

Homosexuality was first classified as a mental disorder in 1968 by the Diagnostic and Statistical Manual (DSM) produced by the American Psychiatric Association (APA).

In 1973, after five years , APA asked her members (psychiatrists) to vote on whether they agree homosexuality to be a mental illness. It was reported that, 5,854 psychiatrists voted to remove homosexuality from the DSM, and 3,810 voted to retain it in the DSM. Consequently, homosexuality was removed from the DSM as a “Mental Disorder”, but was replaced with “Sexual Orientation Disturbance” — a term used for people in conflict with their sexual orientation. It remained therein until it was completely removed from the DSM in 1987.

Concurrently, the World Health Organization (WHO) also removed homosexuality from it’s International Classification of Diseases (ICD) in 1992 and replaced it with “Ego-Dystonic Sexual Orientation ICD- 10. As we speak, The ICD 10 still exist as a form of mental disease.

Social Acceptance

Some societies have zero tolerance for homosexuality they consider it to be repugnant, unnatural and against religious principles. Other societies not only accepted but also embraced it to such an extent that it is now been promoted in educational institutions, music, politics and the movie industry. The social stigma that was once associated with homosexuality in these societies  seems to have disappeared into the thin air. To show you the extent to which homosexuality has evolved, in some western societies  you are not allowed to speak against it , doing so may get you arrested for hate crime (violence against LGBT people).

Final Thoughts

The world is yet to know what truly causes homosexuality. Though one aspect that is often ignored and many fail to speak about is the spiritual aspect of homosexuality  which i believe should be taken very seriously.

In as much as the fact that i respect people’s choices in life and i will continue to do so as a lover of peaceful coexistence. However, what i find disturbing is realizing that schools in western societies teach homosexuality to kids in a manner that go against religious and cultural values that some parents instill in their children. Our desire as parents is to see our children grow up successfully and bear children of their own (the joy of having a grand child). If the whole living organism in the ecosystem decide to be homosexuals, what would then be the faith of humanity?

As we know, everything in the universe exists in pairs (male and female) amongst living organisms. That is one of nature’s beauty and the main reason for reproduction.

The rate at which our societies are evolving is quite alarming. I wont be surprised if Pedophiles stage a “Pedophilia Pride” protest tomorrow, chanting to be recognized and accepted too. From the look of things, they might have started. List of pedophile and pederast advocacy organizations.  See also  Pedophiles want same rights as homosexuals. Surprised? It’s only a matter of time for it to become celebrated.
