Sexual biology research

More information
Homosexuality can refer to both attraction or sexual behavior between people of the same sex, or to a sexual orientation. When describing the latter, it refers to enduring sexual and romantic attraction towards those of the same sex, but not necessarily to sexual behavior. Most scientist today agree that sexual orientation is most likely the result of a complex interaction of environmental, cognitive and biological factors. Although homosexuality does not appear to be adaptive from an evolutionary standpoint, because homosexual sex does not produce children, there is evidence of its existence through human history. Although a number of biological factors have been considered by scientists, such as prenatal hormones, chromosomes, polygenetic effects, brain structure and viral influences, no scientific consensus exists as to how biology influences sexual orientation.

6 areas of research that offer fascinating conclusions on sexuality | TED Blog

As a clinical geneticist, Paul James is accustomed to discussing some of the most delicate issues with his patients. But in early , he found himself having a particularly awkward conversation about sex. A year-old pregnant woman had visited his clinic at the Royal Melbourne Hospital in Australia to hear the results of an amniocentesis test to screen her baby's chromosomes for abnormalities. The baby was fine — but follow-up tests had revealed something astonishing about the mother. Her body was built of cells from two individuals, probably from twin embryos that had merged in her own mother's womb. And there was more.

Biology and sexual orientation

The relationship between biology and sexual orientation is a subject of research. While scientists do not know the exact cause of sexual orientation , they theorize that it is caused by a complex interplay of genetic , hormonal , and environmental influences. Biological theories for explaining the causes of sexual orientation are favored by scientists.

Chief among these antiscientific sentiments, the IDW cites the rising visibility of transgender civil rights demands. Though often dismissed as just a fringe internet movement, they espouse unscientific claims that have infected our politics and culture. The real world consequences are stacking up: the trans military ban , bathroom bills , and removal of workplace and medical discrimination protections, a percent suicide attempt rate and targeted fatal violence. Contrary to popular belief, scientific research helps us better understand the unique and real transgender experience. Specifically, through three subjects: 1 genetics, 2 neurobiology and 3 endocrinology.
