Last week, a 33-year-old woman in California made headlines around the world when she gave birth to eight babies. She had been on fertility treatment and, it emerged, already had six children.

The story sparked an outcry over the ethics of giving fertility treatment to a woman who already has a large family. Now that woman has 14 children to raise.

The California octuplets are sure bucking the trend. Almost all the countries in the world are now experiencing a downturn in fertility, and Japan most of all.
