“Tick-Tock” of the Male Biological Clock

No Comment

Experts suggest that men have a biological clock that begins to tick at middle age.

Looking at males using a fertility clinic, researchers found that a man’s fertility would drop around 7% each year between this 41st and 45th year of age, reducing more rapidly as he began to get older. His sperm quality was also found to decline as he aged.

Scientists studied 570 patients entering a fertility clinic between March 2008 to April 2011. To control for the age of females, all couples who were using eggs provided by young females were discarded.

Results suggested that, of the group of couples who did not conceive, the age of male participants was “significantly higher.”

Furthermore, in a separate study carried out on mice, researchers found that only 35% of mice considered middle-aged were successful in impregnating their female as oppose to 75% of younger mice. In addition, a high number of older mice impregnations ended in miscarriage.

It is expected that as a male hits age 41, a couples chances of conceiving is around 60%, but in only four years this drops to only 35%.

All of the above findings suggest that not only should a couple be taking note of a woman’s age when considering having children, but also a man’s age.

Leader of the research Dr Paula fettback stated, “Of course it’s not the same as for women, but men can’t wait for ever. After 45 if they haven’t, they have to start thinking about having children.”
