Age causes infertility in men: Latest research
LOS ANGELES: Infertility and reproduction problems occur in women after specific age. But latest research revealed that infertility can happen in men too. This research was studied at Reproductive Technology Laboratories in Los Angeles.
According to researchers at Reproductive Technology Laboratories in Los Angeles who analyzed sperm from 5,081 men between the ages of 16 and 72, sperm quality starts to decrease after 35, which means men have a harder time conceiving and carry an increased risk of miscarriage for their partners.
Previous studies put the age of sperm deterioration at 40. “Whether it’s 35 or 40, the message from this and other papers are that men should be aware of age-related changes in their reproductive system and if they wish to become fathers they shouldn’t leave it too late,” said researcher.
Men’s sperm quality seems to deteriorate after the age of 35. The proportion of sperm carrying an X chromosome also seems to increase, meaning older dads are more likely to have daughters.
The study also found a decrease in the ratio of Y to X-bearing sperm once men hit 55, though it is not clear why. It is remember that in men X and Y chromosomes are present from which men donates X chromosomes to daughter and Y chromosomes donates to son.
