The BBC reports that "The number of women aged over 40 becoming pregnant is at a record level, figures from the Office for National Statistics show.
The conception rate for the over 40s in England and Wales rose by 6% between 2005 and 2006, and now stands at 12.2 pregnancies per 1,000 women.
The overall pregnancy rate rose by 3% over the same period, the ONS said.
But teenagers are having fewer babies, with a slight fall in pregnancies among 13 to 15-year-olds.
There were an estimated 866,800 conceptions in 2006, a rise of 25,000 from the previous year.
The most likely age for motherhood was 25 to 29, with a rate of 129 pregnancies for every 1,000 women in this age group.
Four out of five women who became pregnant went on to give birth.
More than half of the pregnancies happened outside marriage, although the figures only cover those where the parents were unmarried at the time of the birth, and both appeared on the birth certificate.
More women are putting off motherhood until their 40s, partly due to advances in fertility techniques which help those who are unable to conceive naturally at that point.
While they and their unborn babies do face slightly increased risks during pregnancy and childbirth, studies have suggested that they are just as able as younger mothers to look after children..."
