Being a gay due to lack of serotonin

In addition to your tolerance for homosexual movement, until now the research about the cause of homosexuality continues to be done. One of them is the study by Yi Rao of Peking University and National Institute of Biological Sceinces, Beijing.

Compounds known to affect serotonin in sexual activity, such as erection, ejaculation, and orgasm. Yi Rao then examined the effect of serotonin on sexual orientation white mice experiments. To investigate, Rao uses white male rats that had been genetically engineered. He made the white rat experiments are not able to produce serotonin by turning off genes that play a role in the production of these compounds.

As a result, white mice without serotonin turns tend to like others of its kind. White mice hummed a love song in an ultrasonic frequency which is usually sung when they want to marry a female. Rao also found that 60 percent of males without serotonin spend the time to caress and smell genital lesbian. While males with serotonin tend to approach the opposite sex.

When Rao inject the compound serotonin, he saw that the mice tend to be attracted to the opposite sex. Meanwhile, when too much serotonin, rats would not be attracted to both types. This shows that the concentration of serotonin in the body of white rats to determine their sexual orientation. Serotonin should be in a certain concentration so that support homosexual or heterosexual behavior.

Does the same thing cause homosexuality in humans? Elaine Hull, an expert rodensia Florida State University who was involved in the research, said, "The same thing might also influence homosexuality or bisexuality in humans." However, he and co-author of the study Zhou Feng Chen reminded that the conclusions of this study can not be taken excessively.

Hail this study do not necessarily explain the cause of homosexuality in humans. "More information is needed to determine the location of the brain involved in the regulation of serotonin at it before jumping to the conclusion that serotonin is a compound that affects the attraction between men," said Hull. The results of this study published in the journal Nature on March 24, 2011 last.

This study is the first time researchers were able to describe the influence of neurotransmitters such as serotonin on sexual orientation. Previously, research on the causes homosexuality have also been carried out, for example, related to the volume of left and right brain. So far, some scientists believe that homosexuality is something that has terberi, not a disease.
