On the left, white text reads \"Two threats to health carry extinction-level consequences, despite their low likelihood,\" with \"extinction-level\" in bold. On the right, two teal circular icons sit above supporting statistics: a radiation symbol icon above text reading \"133 million potential deaths could be prevented by reducing the risk of nuclear conflict by 2100,\" and a hand touching a screen icon above text reading \"10.4 billion years of health loss (DALYs) could be protected through action to reduce the risk of malicious AI,\" each with the numerical figures in bold. In the bottom left corner, \"THE LANCET\" wordmark appears alongside the circular green-and-teal IHME logo and the word \"IHME.\"

ALT Graphic on a cream background with thin teal and cream stripes along the right edge.

ALT Women make up more than half the population, but most of what we know about women’s biology comes from extrapolation of studies in men. This has been changing in recent years, and this special issue highlights some of the progress in understanding the biological basis of sex differences in health and disease and medical issues relevant to women’s health across different stages of life.
