Nurture or Nature: What makes a Transsexual?
This is the big question that is faced by anyone who is or who knows a Transsexual. Because of a number of recent discoveries the balance has been tipped toward nature. There is now evidence that the “Gender Identity Dysphoria” (GOD) has it’s roots in prenatal biology (nature) and not in psychology (nurture).
Transsexual Brain Development
Like the normal male embryo, the male to female Transsexual brain starts out female. Then between the 8th and 24th weeks, the ‘XY’ chromosomes introduce testosterone hormonal changes, but the hormonal washes as faulty. They are either insufficient or ill timed. When this happens, the fetus develops a male body. However, some of the default (original) female brain processes remain intact. Thus, the brain’s gender identity remain intact. Thus, the brains gender identity remains female. This means that Transsexual males whose process of brain masculinization was incomplete, Their default female brains still function. The degree of arrested development can vary. The orgininal brain circuitry that was missed in the masculinizing process provides a continuing feminine influence. This explains why many Transsexuals, biological males know, from as early as 3 years old, that they are actually members of the opposite sex.
How does the FtM Transsexual brain develop?
Like the normal female embryo, the female to male Transsexual fetus starts out as a normal female. Then a problem occurs somewhere between the 8th and 24th week. Even though the ‘XX’ chromosomes have ordered no hormonal washes to take place, testosterone is still introduced. For example: An errant fetal adrenal glad causes testosterone to be produced in great quantities. The fetus is washed with testosterone, against chromosomal orders. The fetal body remains female. However, if the errant wash is strong enough, the female fetus brain is re-wired to think as male. This explains why many Transsexuals, biological males know, from as early as 3 years old, that they are actually members of the opposite sex.
What is the job of the ‘XX’ and ‘XY’ chromosomes?
It seems that one of the jobs of the ‘XX’ and ‘XY’ chromosomes is to govern the introduction of testosterone into the womb. However, chromosomal influence is limited by the many glitches that can happen during the fetal growth process. This is why each human being possesses a unique mixture of male and female traits. Some of these mixes (eg: Transsexualism) make the individuals who have them significantly different from society’s expectations. This causes these people much confusion and suffering. Indeed, there are, in our world, many males who have ‘XX’ chromosomes and many females who have ‘XY’ chromosomes.
Being Transsexual is not a choice
What can be known about Transsexuals?
Transsexualism does not rise from being exposed, in childhood to the clother, toys, activities, and goals of the opposite sex. Nor are Transsexuals; sex addicts, morally corrupt or mentally ill. Transsexuals are simply people who have the body of one sex and the brain wiring of the opposite sex.
