There are many misconceptions about transgender people. But recently, Scientists began to study carefully The causes of neurology, physiology, and psychology behind this. The causes of neurology, physiology, and psychology behind this. Today, we come to science with respect Now the results of scientific research in this area. Hello everyone! My name is Gigi Gorgeous. Came to ASAP Science today This is to talk about “the science behind transgender people”. Before going further, Let’s first understand the genetic sex.
In other words, it is the chromosome in you. The genetic sex is determined after the fertilization is over. That is, when the sperm cells carrying the X and Y chromosomes From men When imported into female ovaries with X chromosome. However, until 6-7 weeks after the end of the fertilization process, “XY” and “XX” embryos The gonads are the same. Around the 7th week, Because on the Y chromosome A gene called “SRY” Male sex organs begin to develop. This allows sperm cells to develop towards male sexual characteristics, Produces “testosterone”, Stimulates the penis and testicles Isomale structure Development. At the same time, other cells degenerate female reproductive organs, In order to prevent the development of female sexual characteristics.
However, in the development of female sexual characteristics, Because there is no “SRY” gene carrying Y chromosome, The female reproductive organs are kept intact, And stimulated by estrogen and renal secretions, Grow into uterus, cervix, upper vagina And fallopian tubes. But things are not always that simple. Sometimes, there will be “rare pairing” of chromosomes, For example, “XXY”, “XXX”, “XXYY” and so on. There will even be people who carry the XX chromosome Male genitalia and sexual characteristics develop.
This is because the Y chromosome breaks, The broken part swapped positions with the X chromosome. But in fact, the gender differentiation of the brain It is much later than gonad differentiation. Yes, despite the controversy, Brain structure and function of men and women Considerable difference! research shows, Male brain, Cerebellum And hippocampus are usually larger than women. And female The concentration of the left frontal lobe is higher, The right frontal lobe has a larger capacity. So we are in the end In the brains of trans people What will you see? Some studies show that Transgender brains, Whether it is structure or function Are closer to their gender identity, Not physiological sex. One study found that transgender women Although the biological sex at birth is male, Ta’s hippocampus is still a smaller female structure. The MRI scan results also proved that Transgender brain structure Closer in thickness Their empirical characteristics, not physical sex.
Eventually, androstenone (male pheromone) caused Different hypothalamic reactions in the male and female brains. In this case, the “gender anxious” individual’s hypothalamic reaction Fit with their perceived gender rather than their physical gender. These studies help us present such a thing: The virilization and feminization of gonads Does not always match the brain, Moreover, your sexual characteristics, anatomy With your gender, or your perception of your body, There are differences. In addition, the characteristics of transgender people It also seems to be related to genetic makeup. Let’s look at family history, The gender characteristics in the family are consistent, In other words, gender characteristics may be inherited. Controls the body’s sex hormone levels “CYP17” gene, Has a variant allele, It often occurs in transgender men.
Although there is a need for more in-depth research support, But scientists have now observed Over 3 million genetic markers with transgender characteristics, To study the relationship between transgender and genes. However, although scientific research has Confirmed the rationality of the transgender experience, There are still many transgender people experiencing More severe depression and anxiety than the general public. Transgender suicide probability Bigger than the average person, When they are not accepted by the family, At work and in the medical system When suffering discrimination. Probability of suicide It will decrease after transgender people have completed transsexual surgery. In other words, gender anxiety may cause Extreme emotional and psychological pain, It even led to suicide. If you, or your family, friends Is experiencing gender anxiety, Here are a few links Provide you with more information. Gigi, thank you so much It’s time to record this video. This is too important for us! Glad you can do this with us. thank you Use your channel, your platform, The science behind the experience of science transgender people, This brings us one step closer to gender equality.
