One in four hit by miscarriage
MISCARRIAGES occur in around one in four recognised pregnancies. The vast majority – 85% – happen within the first 12 weeks and many women will not have even known they were pregnant.
It’s thought most miscarriages are caused by abnormal chromosomes – the genetic ‘building blocks’ – in the baby. For most women, a miscarriage is a oneoff event and they go on to have a successful pregnancy.
Michelle Obama said she realised the ‘biological clock is real’ when she was 34 or 35 – women’s fertility starts to decline after 30 but more rapidly after the age of 35.
As women age both the number and quality of the remaining eggs declines, making it more difficult to conceive.
Men’s sperm quality also declines, typically between the ages of 40 and 45, reducing their fertility.
