From the article sighted:
“Starting just over one year after the beginning of the famine, Song found a sharp dip in the proportion of boys being born — falling from 109 boys born for every 100 girls in April 1960 to 104 boys for every 100 girls by October 1963, about two years after the famine ended. The ratio did not return to pre-famine levels until around July 1965.”
So I don’t think this lives up to the headline. The ratio does not skew to more females, it skewed to slightly less of a male dominance. My alternative hypothesis would be that male infants, which have a single X chromosome, may be more sensitive to environmental factors. And while their mothers were starving they may have in their desperation may have consumed odd plants, spoiled food, clays and dirt. Which may have led to birth defects which ended more pregnancies of males than females.
