Jessica Biel: Women’s Reproductive Health Shouldn’t Be ‘Taboo’

— -- Jessica Biel is an actress, wife and new mother, and now she’s taking on the issue of women’s reproductive health.

Biel and her friend, Saundra Pelletier, CEO of WomanCare Global, an organization that focuses on women's reproductive health, are launching an online video series to teach women about their bodies.

The two women chatted with ABC News' Amy Robach on "Good Morning America" about the project titled “If You Don't Tell Them, Then Who Will?"

The videos -- which cover topics including contraception and puberty -- will be launched today on the comedic website Funny or Die. Biel said there’s humor in the campaign.

“I mean that's really how we want to speak about this issue and share this issue with everyone. Because we want to take it out of the shadows,” said the 33-year-old actress. “We don't want women's reproductive health issues to be hidden under stigma or taboos anymore. And how best to reach all demographics. Can we please laugh about this crazy stuff that happens to us?”

Biel gave birth to a son, Silas, in April. He is the first child of Biel and her husband, Justin Timberlake.

The actress, who starred in the "Blade" film franchise, told Robach that she knew “nothing” about the changes her body would experience during her pregnancy.

“The specifics of ‘Well, what does my body need to go through?’ I knew nothing,” she said, noting that the lack of knowledge goes back all the way to middle school.

“I remember my health class in middle school literally was the girls were separated, the boys were separated, and I think it was ‘Here's a tampon, good luck’ kind of thing,” she said. “And you just walk away from that experience feeling kind of shameful. And you feel kind of weird and like, it was kind of gross.”

According to the U.S. Centers for Disease Control and Prevention, about half of pregnancies in the United States are unplanned.

Pelletier acknowledged that “a lot of good information” on the subject existed, but added: “We want to bring it all together because we know that young women and young men are getting information sometimes in the wrong places.”

Robach asked Biel how her husband felt about her involvement in the project.

“Well, he supports everything that I do and that's I think why he's a wonderful partner. And we should just be able to talk and laugh and learn together,” Biel said.
