Scientists have for the first time created male and female stem cells from the same person. This means the cells are genetically identical except for the sex chromosomes, enabling a new platform for studying sex differences in drugs and diseases.

For decades, doctors have noticed men seem more likely to develop cancers compared to women, and while it was often waved away as due to lifestyle, a new study suggests biological factors may be the biggest player in the different cancer risk.

A new review article has discovered females are much more likely to suffer from long COVID than males. The findings are curiously distinct from earlier studies that show men more often experience severe acute disease from COVID-19 compared to women.

A study tracking testosterone in hospitalized COVID-19 patients found a link between low levels in men and severe disease outcomes. The research offers important clues as to why men seem to be at greater risk of death due to coronavirus than women.

A new study has affirmed men seem much more vulnerable to COVID-19 than women. The study found men, independent of age, are more likely to contract the virus, suffer from severe complications, and die from the disease compared to women.
