Homosexuality- The Major Cause of Homosexuality The origins of human sexuality and homosexuality in particular have puzzled philosophers, theologians and ordinary people for thousands of years. In scatter cultures, homosexuals have been regarded as a normal part of life, however, same sex attraction to most cultures have been treated as an unforgivable sin or a terrible crime. Many psychologists and psychiatrist had attempted to "treat and counsel" the homosexuals. In our social norm, male attracts to female and female attracts to male. To everyone this is a natural and biological urge. However, there is a significant minority who attracts to their own sex. It's about five percent of the population in the world. There are many opposing viewpoints of whether it derives from variation in our genes or our physiology, from the intricacies of our personal history or from convergence of these? Is it for that matter a choice rather than a compulsion? Chances are no one factor or study can alone explicate and clarify the human sexual orientation. However, there are evidences that prove being gay is not a choice. The nature of homosexuality primarily comes from one's biological sexual orientation and the environment is just a source to bring forth or repress the behavior Many researchers and scientists have long search for the distinguishable brain structures, the biochemistry in the human brains to differentiate the differences to classify between the two obvious sexes we now have in our society, male and female. Such sex differentiation of the brain's structure is called sexual dimorphism. . (LeVay/ Hamer 22) The first significant observation of sexual dimorphism performed in an animal laboratory. Roger A. Gorski, a professor at University of California, Los Angeles, conducted an experiment on rats. In 1978, Gorski examined the rat's hypothalamus, a region at the base of its brain that is involved in instinctive behaviors and regulation of metabolism.
