Identical twins have increased chances of both being transgender rather than dyzgotic twins

>Combining data from our independent findings with those from past research, 13 of 39 male MZ twin pairs (33.3%) were found to be concordant for transsexual identity and eight of 25 (22.8%) female MZ twins were found concordant. In comparison, concordance between either male or female DZ twins was low or zero (1/38 = 2.6%; Table 5).

>Notably among our responding twins were three sets who had been reared apart and were concordant in transitioning. One was a male set within which the brothers were separated at birth, another was a set of males separated at age 4, and the third was a female pair separated at 14. Each had independently and unknowingly transitioned and found out about each other’s switch as adults after the gender shift.

When normal males have their dicks amputated for medical reasons, almost all experience phantom penile syndrome.

Way less trannies experience this. FtM trannies experience phantom penile syndrome.

V.S. Ramachandran "Occurrence of phantom genitalia after gender reassignment surgery".

>Around 60% of cis-men who have had to have their penis amputated for cancer will experience a phantom penis. Data from several dozen post-operative subjects lends support to our prediction that they have a lower incidence of phantom penis/breast sensations than ‘‘normal’’ individuals who have undergone amputation of the same appendage, for other medical reasons.

>More remarkably our prediction that female-to male transsexuals would have a phantom penis also (1002 Ramachandran and McGeoch) seems to be correct. Indeed, more than half of the around 30 female-to-male transsexuals we have interviewed, claim to have experienced this, often since early childhood.

I know it's not a popular opinion here, but Transgender is a real thing. It's just way over represented compared to the actual number of people who are transgendered, who are maybe like 0.1% of the population.

This desu.

I agree. I also think some that transition DO get pushed into it in a way. But I think the percentage of those that transition that are not biologically transgender is WAY lower than it's represented as well.

I saw someone mention in a different thread about how Sup Forums agrees that empathy and intellect is genetic but can't accept gender identity is biological too.

Berglund "Berglund, H. et al. “Male-to-Female Transsexuals Show Sex-Atypical Hypothalamus Activation When Smelling Odorous Steroids". A positron emission tomography (PET) study showed that smelling androgens (male pheromones) caused transwomen to respond in the hypothalamus region of their brain in a manner similar to XX karyotype women. However, smelling estrogen-based pheromones also caused them to respond in the hypothalamus region in a manner similar to XY karyotype men. This combination of results suggests that transwomen occupy an “intermediate position with predominantly female features” in the way the hypothalamus reacted.

Yokota, Y. et al “Callosal Shapes at the Midsagittal Plane: MRI Differences of Normal Males, Normal Females, and GID”. An MRI study of 22 transwomen and 28 transmen examined the shape of the corpus callosum in the brain at a specific cross-sectional plane, and compared this shape with that observed in 211 XY karyotype males and 211 XX karyotype females. Their results demonstrated that not only could the sex of the patient be determined with 74% accuracy from the MRI picture, but the shapes of the brains in the transsexuals strongly reflected their gender, and not their biological sex.

Zubiaurre “Cortical Thickness in Untreated Transsexuals”. A 2012 study examined cortical thickness in the brain between 29 XY karyotype males, 23 XX karyotype females, 24 transmen, and 18 transwomen. None of the transsexual subjects had received any hormone treatment prior to the study. Using an MRI, the researchers found that the transwomen had more cortical thickness than the XY males in three regions of the brain. The transmen showed evidence of masculinization of their grey matter. In all transsexuals studied, the key differences from their biological sex were found in the right hemisphere. On a graph, transpeople statistically fell in the middle between the XX and XY karyotypes.

Swaab "Sexual differentiation of the human brain: relevance for gender identity, transsexualism, and sexual orientation." Analysis of prenatal androgen exposure similar to Gooren, but notes that neurological testosterone availability in MtF trans people is deficient, causing transgenderism or non-heterosexualism.

Garcia-Falgueras "A sex difference in the hypothalamic uncinate nucleus: relationship to gender identity." The structure of the anterior hypothalamus plays a strong role in the development of transgenderism; INAH3 volume in transwomen resembles ciswomen, and INAH3 volume in transmen resembles cismen.

Luders "Regional gray matter variation in male-to-female transsexualism." MtF transgender people were analyzed by fMRI; gray matter variation throughout the brain more closely resembled the layout of a cisfeminine brain, rather than that of a cismasculine brain, implying gender identity depends on cerebral layout.

Rametti "White matter microstructure in female to male transsexuals before cross-sex hormonal treatment. A diffusion tensor imaging study." By diffusion-tensor-imaging MRI and fractional anisotropy analysis of various transgender and cisgender people, FtM transgender people more closely resembled a masculine-structured brain than a feminine- structured brain, noted by the study in the structures of the right superior longitudinal fasciculus, the foreceps minor, and the corticospinal tract. White matter microstructure therefore plays a role in gender identity.

Burke "Hypothalamic response to the chemo-signal androstadienone in gender dysphoric children and adolescents". Androstadienone, a particularly fragrant chemosignal responsible for sex-based differences in hypothalamic microstructure; children with gender dysphoria were observed to express differences in hypothalamic activation in accordance with identified gender, rather than assigned gender.

It's a disease, just like people who have a manic wish to amputate their limbs or get cancer (yes, that's a thing).

Boston University Medical Center. "Transgender: Evidence on the biological nature of gender identity." The researchers conducted a literature search and reviewed articles that showed positive biologic bases for gender identity. These included disorders of sexual development, such as penile agenesis, neuroanatomical differences, such as grey and white matter studies, and steroid hormone genetics, such as genes associated with sex hormone receptors. They conclude that current data suggests a biological etiology for transgender identity.

Bao, Hahn, Kranz, Kaufmann "Structural Connectivity Networks of Transgender People". 94 subjects, 23 FtM, 21 MtF, 25 cisFemale, 25 cisMale: average age 26. Transsexual subjects did not fulfill criteria for current comorbidities but 9 reported history of depression (n = 2), specific phobias (n = 3), obsessive compulsive disorder (n = 1), anorexia nervosa (n = 2), and substance abuse (n = 4). All patients reported subjective feelings to belong to the other gender before or at puberty. Investigating structural networks in female-to-male and male-to-female transsexuals, we observed differences in hemispheric and lobar connectivity as well as local efficiencies when compared with healthy controls.

Bentz "A polymorphism of the CYP17 gene related to sex steroid metabolism is associated with female-to-male but not male-to-female transsexualism." CYP17 -34 T>C SNP allele frequencies were statistically significantly divergent between FtM transgender people and cisfemale controls; genotype distributions were also divergent in a statistically significant manner.

Thanks OP for that pic, literally the only tranny I feel OK jacking off to because "she" technically has two XX chromosomes, now that I see what "she" looked like as a dude before the whole illusion is fucking ruined

Fuck you OP

i want a tranny gf

>25 is a good sample size
mmhmm

This just shows that mental illness is heritable

Schizophrenia has a 50% concordance rate for identical twins. Schizophrenics also have measurably different brains.

checkmate transfaggot

It's 25x the sample size the "Pimozide study" has.

checked but i don't think it's that. an identical twin will have an even stronger desire to be a special snowflake than your attention whore since he has a clone

It is totally a real thing but that doesn't change the fact that transitioning is a mistake for the majority and they will never live happy lives. They are usually mentally ill outside of their transgenderism too. I am not hateful of any individuals who transition but when you see old fuckers suddenly transition like Caitlyn you have to wonder how they survived up until that point if it is really so tough. Imagine if Jenner just lived their life normally but had the correct therapist.

*average

All of this is better explained by the fact identical twins are more likely to both be homosexual.

Tranny-ism is self-hating homosexuality. It's a transmissible mental illness.

No, it isn't a real thing. It's a mental illness caused by modern medicine.

Maybe.

Regardless, we shouldn't normalize it or exalt people who transition.

Considering how rare the circumstances are I'd say there's a probable reason to buy into the correlation. We already know intelligence and bipolar disorder have genetic influence so I don't see why gender dysmorphia is any different.

I wonder how much Soros will pay them to exchnage their genitals and do interviews.

Every one of your faggots can fuck off back to /lgbt

There's like 8 Trap threads right now.

You want to stop violence toward sexual freaks Start by keeping it to yourself.

The problem is, it doesn't mean what you think it means.

Tranny-ism is one of two things. Either self-hating homosexuals, or straight men with a fetish for being female.

Identical twins are a lot more likely to be homosexual, and that's what this study found. Most of these twins were homosexual males.

Other studies on trannies found their samples were more likely to be """lesbians""", ie straight autogynephiles.

In other words, this sample of identical twins was just showing what would be expected: if one is a self-hating homosexual who wants to cut his dick off, the other one probably is too.

If tranny-ism was real these twins would look like the other studies of trannies: mostly tranny "lesbians".

>tfw half the degenerate fetishes that came about after WW2 originate from KGB experiments

>13 of 39 male MZ twin pairs...and eight of 25 (22.8%) female MZ twins

This is an argument for some effect of the shared environment. The fact that only about 33% of Transseual twins have the same transsexual 'identity' as the other twin is powerful evidence that the cause of Transsexuality is not genetic in nature.

Could this suggests that something at birth triggers sexual deviations?
