"I think when you have a cluster of girls who are friends with one of the stars of the show and they all get pregnant by accident, there's something wrong," Coen of Jezebel.com said.
"It's not an accident. That has to do with how teenagers equate success. 'I want to be famous,' they think. 'I want to be on television,' they think. 'Look at this teen mom. She's on the cover of a tabloid magazine.'
"That seems great when you're young."
MTV said, "We absolutely don't solicit and would never knowingly cast anyone who chose to get pregnant on purpose. That is the exact opposite of the intent of the show."
Indeed, the National Campaign to Prevent Teen and Unplanned Pregnancy supports MTV's "16 and Pregnant." The organization conducted a poll indicating the 82 percent of teens who watched the show thought it helped them better understand the challenges of teen pregnancy and parenthood, and how to avoid it.
A few weeks after her interview with ABC News, Corinna gave birth to Khaley Laree Perussquia.
"I think she's beautiful," Corinna said.
Corinna's mom, Melanie Valasquez, said, "It feels good. Kind of feels like she's mine."
But the baby is Corinna's, and the new mom is having a hard time adjusting. Instead of joy, there are tears of frustration.
For this teen mom, there won't be photo spreads or a cushy TV salary; just family rallying around to help.
Corinna's grandfather is supportive but disappointed.
"Young kids don't understand," he said. "They think it's going to be fun and all. It's not fun.
After a four-week school maternity leave, Corinna will struggle not to become a statistic; one half of all teen moms drop out of high school. But Corinna plans to graduate, while her mother watches the baby.
Purvis, too, is back to regular life. Now that the MTV cameras are gone, she's waitressing tables at the local pizza joint, trying to make ends meet to support her baby son. She loves her child but regrets the timing, she said.
"If I could go back in time, I would have waited, I wouldn't have had sex without a condom," Purvis said.
She laments a childhood left behind. "There's so many things that I wanted to do," she said. " ... I've always wanted to go to prom and I didn't even get to do that."
She says pop culture's version of teenage motherhood isn't always in line with reality. "They all have new cars ... they're in magazines, they're going to 'Dancing With the Stars,' stuff like that," Purvis added. " I mean, it just seems like it's that easy."
As part of the filming process we sometimes ask cast members to talk about their stories to provide context and background on what they're going through, but we do not influence the stories in any way -- this is a documentary and our cameras are there to capture real life situations as they unfold.
We absolutely don't solicit and would never knowingly cast anyone who chose to get pregnant on purpose -- that is the exact opposite of the intent of the show.
