Couples who want to start a family, better plan it early in your life because the more you delay, the stronger becomes the risk of a miscarriage, say the scientists. And this applies to both men and women. Contrary to the older belief that men remain fertile even at old age, this new research points out that delayed fatherhood can also cause miscarriage like late motherhood.
Delayed fatherhood for men is a cause of concern for a healthy pregnancy and the baby as well, doctors warn, after a recent research found that male fertility begins to decline when they reach their mid-30s. Doctors said men who wait until their 40s before starting a family face a greater chance of their partner having a miscarriage, because of the poorer quality of their sperm.
The researchers studied the records of more than 12,000 couples treated for infertility at the fertility clinic, Eylau Centre for Assisted Reproduction in
The study looked at pregnancies and miscarriages recorded for couples having IUI treatment at the clinic. It found the risk of miscarriage was on average 16.7% when men were aged 30-34. That rate rose to 19.5% when men were 35-39 and 33% in men aged 40 or over.
The findings are a concern, researchers say, because of the trend for men to delay fatherhood.
Previous research has pointed to a slight increase in birth defects in babies born to older men. A 2005 study of 70,000 couples by epidemiologist
Normally, men don't typically worry about reproductive ageing, but perhaps they should if the study is to be believed, as now, delayed fatherhood is also being linked to miscarriages, and birth deformities.
