Director general Mark Thompson is said to have made the request of news director Helen Boaden, the BBC reports.
A BBC spokesman said: "News has a pretty good story to tell with Kirsty Wark, Martha Kearney and Maxine Mawhinney all flourishing - as well as highly experienced women out in the field like Bridget Kendall, Caroline Wyatt and Orla Guerin.
"However, we'd be the first to say that it's important not to rest on our laurels in this area and ensure we reflect the public we serve. And of course, this isn't an issue just for the BBC - other broadcasters face the same challenges."
Broadcaster and government adviser Dame Joan Bakewell said that she had held meetings with Thompson and Boaden where it was agreed that there was "a case to be answered" in this area.
"I said there was a conspicuous absence of older women, of all the segments in society, that isn't seen," she said.
"We get lots of jowly white-haired men, that's no inhibitor of employment for them, but it seems to have been eliminator for women until now. I'm glad it's changing."
Earlier this year, Bakewell accused the BBC of getting rid of female newsreaders once they reach 50.
