When it comes to reproductive health, women have always been in the lime light and it’s as if men have been relegated to the background. A study by Bronte Stone at Reproductive Technology Laboratories in Los Angeles and his colleagues has something to say about men’s reproductive health: men's sperm quality seems to deteriorate after the age of 35 and the proportion of sperm carrying an X chromosome also seem to increase, meaning the older the man, the more likely he is to have daughters.
Bronte Stone and his colleagues analyzed sperm samples from 5081 men aged between 16 and 72. They found deterioration in sperm quality and quantity after age 35. Previous studies had suggested that the decline doesn't start until about age 40.
The message here is 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.
