LOS ANGELES — Sex selection in parts of China and India is expected to produce a 10 to 20 percent excess of men in the next two decades, the Los Angeles Times reported Monday.
Citing research in the Journal of the Canadian Medical Association, researchers say cultural preferences for sons combined with ultrasound technology has produced a shift in the number of boys born.
In nature, about 105 boys are born to every 100 girls. In parts of China, that ratio is now 130 boys to 100 girls and in India the ratio in some areas is as high as 125 to 100.
Both countries have laws against sex selection, but they are not enforced, according to the Times.
The researchers, from the University College London Centre for International Health and Development, note that many men in these areas will not be able to marry because of the disparity in the sexes, which is expected to lead to a rise in crime rates and psychological problems.
“Nothing can realistically be done to reduce the current excess of young males, but much can be done to reduce sex selection now, which will benefit the next generation,” they wrote.
