China's current population is estimated at ~1.34 billion people.
Assume half of those people are between 15-40 (child bearing age), and we have ~670 million. Assume 48% of those people are female, and now we have ~320 million women of child bearing age.
If China has become a world filled with girls-gone-wild promiscuity, then there would be a fairly high chance of sperm fertilizing egg for any one of these child-bearing age women.
Let's say the average girl manages to figure out what to do with the penis once a week. Assuming no contraception, that gives a ~14% chance of any given month resulting in a rapid abortion. With 12 months/year, that means that without contraception the average child-bearing age woman would need an abortion ~1.7 times/year... or China would need to abort or birth ~544 million fetuses/year.
Michelle then goes on to state that 13 million abortions are performed, and 10 million pills are purchased per year - or 23 million fetuses are aborted/year. Add to that ~19 million births/year... and we see a total of ~42 million fetuses being conceived each year.
That's ~8% of what you might expect in a country that is utterly clueless concerning contraception... assuming that they only had sex once/week. If they had sex 7 days/week, obviously that would mean only 1% of the country couldn't figure out the intricate complexities of the condom technology...
Which means that something in the story might be a wee-bit exagerated... or China actually has a pretty good sex-ed system and one person that Michelle talked to managed to miss it.
I support good sex-ed, but I don't like it when someone pushes a bullshit story to try to argue for a sound policy.
