Most of us don’t need to be told,We see it when we look at our mothers. The truth is that the stresses of parenthood have aged them. And now a study has proved them right.

Researhers have found that women’s ageing is accelerated by up to two years every time they give birth.

It means the more children a woman has, the shorter her life expectancy may be. The study, on more than 3,200 women aged 20 to 22 in the Philippines, found each birth has a damaging effect at the cellular level.

Some Mothers with several children saw their cellular age increase by half a year to two years each time they had a baby, the researchers at Northwestern University, Illinois, found.

They looked at two markers of cellular ageing – telomere length and epigenetic age – both of which they said ‘independently predict mortality’.

Lead author Calen Ryan said: ‘Both [markers stated above] appeared ‘older’ in women who had more pregnancies in their reproductive histories. Even after accounting for other factors that affect cellular ageing, the number of pregnancies still came out on top.’

The team said the cellular changes during pregnancy may be related to adaptive changes in the mother’s immune system.

They are now carrying out a follow-up study on the women, who had their first measurements taken in 2005, to see if their cells still appear older in later life. The study was published in Scientific Reports.


But there is also a counter position that states women who do not give birth stand a risk of getting ovarian cancer. Due to cells that thrive on conception beginning to Multiply abnormally in the absence of Fertilization. Plus there is the woman in Philippines who lived u[ to 106 who had nine kids. Showing that there are some exceptions to the research but  from a physical and Psychological stand point the effects of pregnancy on a woman are palpable.
