When Sarah Gardner was 34, she started getting really worried about whether she'd ever have kids.
"I bought this kit online that said that they could tell you your ovarian reserve," Gardner, now 40, says. These kits claim they can tell women how long their ovaries will continue producing eggs and how much time they have left to get pregnant.
"Well, mine said, 'we advise really you have a baby now.' Well, sadly that letter arrived three weeks after I just split up with my long-term partner. So, yeah, it opened a massive can of worms really," she says.
It's been known for a while that girls start puberty earlier than they did in the past, sometimes as young as 7 or 8. But it's been unclear whether boys also go through puberty earlier. Now, a study from the American Academy of Pediatrics helps answer that question.

DAVID GREENE, HOST:
And I'm David Greene. This afternoon, President Obama is set to nominate Massachusetts Senator John Kerry as the nation's next secretary of state. Kerry would replace Hillary Clinton, who's planning to leave that post after four years as the president's globe-trotting emissary. Joining us to talk about the move is NPR White House correspondent Scott Horsley; and NPR's diplomatic correspondent Michele Kelemen, who's here in the studio with me.
