20% of women born to mothers over 30 years never conceive, study finds
How old your mother was when you were born may affect if you would go onto have children, a major study concludes.
Nearly 20 per cent of women born to mothers older than 30 went on to never have children, researchers discovered.
While the figure was only 13 per cent for those born to teenage mothers and 15 per cent for those whose mother gave birth between 20 and 24.
The results, made by Canadian scientists assessing pregnancy records of 43,000 women in the United States (U.S.), come amid a surge in older mothers.
Delayed pregnancies are usually made by women who have instead decided to focus on establishing themselves a career.
And the new findings, which have been dubbed ‘surprising’ and published in the journal Human Reproduction, support that theory.
Women who had a post-graduate degree were the most likely never to have any children, according to the McGill University team.
Their chances of having children were found to be lower than lesbians and those who had never married, New Scientist reports.
