Today, the extreme male brain (EMB) theory is the main rival to the imprinted brain theory—at least where explaining autism is concerned. A new study has looked for direct evidence of the effects of ...

The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...

For years, we’ve been taught that men have one X and one Y chromosome, with the Y carrying the vital gene that initiates male development. But now, scientists are sounding the alarm: the Y chromosome ...

Humans typically have 46 chromosomes arranged in 23 pairs. One of these pairs determines biological sex at the time of conception. Males usually have one X chromosome and one Y chromosome. The ...

In mice, female germ cells can develop into viable ova in male testes, Japanese researchers report this week. Their paper in PNAS suggests that sex determination occurs early in embryonic development ...
