Women's fertility declines in late 20-s, not 30-s

A woman's fertility starts to decline in her late 20-s, not in her 30-s, as had been thought.
But the scientists who conducted the new research stress that a woman aged 28 does not have a smaller chance of becoming pregnant overall.

"Although we noted a decline in female fertility in the late twenties, what we found was a decrease in the probability of becoming pregnant per menstrual cycle, not in the probability of actually achieving a pregnancy," says David Dunson of the National Institute of Environmental Health Sciences in North Carolina.

A woman aged 28 should take only 1 - 2 months longer to become pregnant than a woman aged 23
, he says.
