New study probes the genetic roots of transgender identity

New research suggests the expression of some sex hormone genes can influence a person’s sense of gender identity

A new study led by researchers from the Hudson Institute of Medical Research in Australia has identified 12 significant genetic differences between transgender women and non-transgender males. It is hypothesized that these genes, known to be involved in sex hormone signaling, possibly contribute to a person’s ultimate sense of gender identity.

The study analyzed the DNA of 380 transgender woman, compared to a control of 344 non-transgender males. The results identified twelve functional genetic variants in transgender women correlating with genes involved in regulating the sex hormones estrogen and androgen.

“This is the world’s largest and most comprehensive study examining changes in genes that control sex hormone signaling in transgender women,” says lead author on the study, Vincent Harley. “It identifies several new genes or genetic variations never before looked at in gender dysphoria.”

Researchers Tracked A Wild Salamander That Stayed Completely Still For Seven Years

Sometimes you find a tiny patch of rock in an underwater cave that’s so perfect that you just have to sit there for seven years without moving. According to a new study in the Journal of Zoology, a salamander living in a cave in Bosnia and Herzegovina has done just that, after it was observed on the exact same spot for 2,569 days.

Skeletal Studies Show Sex, Like Gender, Exists Along a Spectrum

Skeletal Studies Show Sex, Like Gender, Exists Along a Spectrum

An increasing recognition of this complexity by researchers and the public has affirmed that gender sits on a spectrum: People are more and more willing to acknowledge the reality of nonbinary and transgender identities, and to support those who courageously fight for their rights in everything from all-gender bathrooms to anti-gender-discrimination laws. But underlying all of this is the perception that no matter the gender a person identifies as, they have an underlying sex they were born with. This represents a fundamental misunderstanding about the nature of biological sex. Science keeps showing us that sex also doesn’t fit in a binary, whether it be determined by genitals, chromosomes, hormones, or bones…

A new study that was conducted with 85 non-conforming children, aged three to 12, has found that children perceive their own genders earlier than previously thought. The team asked study participants how close they felt to boys or girls, and which gender they were.
