Men Over 40 Less Able To Father Children – Study Finds

A recent French study has confirmed that women are not the only ones who have cycles, men, too, have biological clocks, which kick in their mid-30s. This study indicates that men aren?t excused from reproductive ageing.?

The most significant effect, and one which will have a strong impact, especially on foreign men in Pattaya, is that a man’s age affects his ability to father a child. The male sperm is apparently most viable in their 20s, and drops thereafter. Even mobile phone use is thought to affect male fertility!

Dr Stephanie Belloc presented the work to the European Society of Human Reproduction and Embryology (ESHRE) conference in Barcelona in late June, 2008. She declared: “This research has important implications for couples wanting to start a family.” She stated that the French study was conducted using over 12,200 infertile couples who had sought treatment at the Eylau Centre for Assisted Reproduction in Paris between January 2002 and December 2006. The findings are :

? chance of a successful pregnancy falls when the man is over 35, and even more over 40.
? males under 25 can get a woman pregnant five times quicker than men over 45
? conception time averages for a woman with a partner under 20 were 4.5 months
? conception time averages for a woman with a 50+ partner were 26 months
? compared to men who were under 25, men over 45 were nearly five times as likely to have a time to pregnancy of more than one year and more than 12 times as like to have a time to pregnancy of more than two years
? with a father in his late 30s, miscarriages were more common than if the man was younger.

Researchers say this is the first time such a strong association has been found between age and male fertility in the time it takes to conceive a child and in fact male age was more of a determining factor than the woman’s age.

Although age was the most significant factor that affected the time it took to conceive, other factors contributed, such as caffeine or alcohol use and smoking, frequency intercourse and the age of the woman.

However, many men still maintain their fertility, according to Dr. Rebecca Z. Sokol, president of the Society of Male Reproduction and Urology, who said: ”If you look at males over 50 or 40, yes, there is a decline in the number of sperm being produced, and there may be a decline in the amount of testosterone, but the sperm can still do their job.”

Other studies, though, have indicated more ominously, that as men get older, they face an increased risk of fathering children with abnormalities, such as:
? increased fragmentation of DNA,
? increased rates of some cancers in children
? increased risk of certain rare birth defects like achondroplasia, (dwarfism). neurofibromatosis, the connective-tissues disorder Marfan syndrome, skull and facial abnormalities and many other diseases and abnormalities.

”As paternal age increases, there is an increased frequency in new mutations,” Dr. Joe Leigh Simpson, president-elect of the American College of Medical Genetics.
