Women Will Become More Fertile in 40s, Says Study
The trend for having children later in life could lead to women becoming more fertile in their 40s, researchers at a British university have suggested.
As many women wait until they are older to give birth, only those with longer lasting fertility genes will be successful. That means the average length of fertility will grow as their genes will be passed on to their children.
The study from the University of Sheffield shows that previously women would marry early and if widowed was too old to remarry thus favouring early childbirth in women, The Daily Telegraph reported Thursday.
But today’s reluctance to settle down and reproduce until later in life could lead to fertility beginning to favour older women.
