Methods of sex selection of births

drigg's cron started!

In some countries as China, India, and South Korea it is allowed to check the sex of fetuses and then abort if it's not what parents are waiting for.

Some more sophisticated and expensive methods involving in vitro fertilization, drugs to stimulate the mother’s ovaries, and surgery, allow parents to know what will be the gender of their child before the woman even becomes pregnant, but these processes price is around $20000 in America and around $5000 in Thailand, so this method clearly is only available to the richest.

And some worldwide experts said that it is unethical for physicians to help parents select their child's sex if it is not based on potential for sex-linked genetic disorders, but solely on family balancing of personal preferences.

One's must also remind that social consequence of the sex ratio is that, assuming a given average number of births per mother, the effective population replacement rate is proportional to the percentage of women, and preference for male babies might restrain the growth of the population.

Then, having too many males in a population is likely to be a source of political unrest, because such gender imbalances are incompatible with a peaceful democracy, and, in addition, in a male-dominated society, girls may end up being hoarded by their families as a precious resource.
