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.

Turn 50, and you can pretty much count on an invitation to join the AARP and a referral to the gastroenterologist to be screened for colon cancer.
Two-thirds or less of people ages 50-75, the target range for colorectal cancer screening, are up-to-date on testing, according to the Centers of Disease Control and Prevention.
That's better than it used to be, but still isn't up to par. The national screening goal is 70.5 percent of eligible people in 2020.
