One in four hit by mis­car­riage

Scottish Daily Mail - - News -

MIS­CAR­RIAGES oc­cur in around one in four recog­nised preg­nan­cies. The vast ma­jor­ity – 85 per cent – 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.
