Female embryos are more likely to die during pregnancy, scientists have claimed, overturning a long-held belief that males are more vulnerable in the first months of life. The latest work suggests that the opposite is true, and if confirmed would undermine a large body of academic research and shed new light on the different challenges faced by males and females during the early phases of development. Under normal circumstances, the sex ratio of babies at birth is slightly skewed towards males, with around to male babies for every females — without any artificial intervention. Scientists had explained this by suggesting that more male embryos than females are conceived. It was also thought that more males died during development, based on the observation that a greater number of male babies are miscarried or stillborn during the final trimester of pregnancy. The findings also raise new questions about observed demographic trends, such as the increase in females born following severe food shortages, or the peak in male births during wartime.
