[narrator] This is a stretch test, which engineers use

to measure the strength and stretchiness of materials, like rubber.

But here, it's testing something different:

The cervix is the gate between a woman's uterus and her vagina.

-like a penis, from going any further up. -[whistle blows]

[narrator] And it stops important things in the uterus,

like a growing fetus, from coming down too early.

You have to keep the air in the uterus or the baby inside the uterus,

例如防止發育中的胎兒太早出生

and that cervix is the knot that keeps the uterus closed.

As an engineer, what's really struck me about the cervix

is that a pregnant specimen in the lab...

It just keeps stretching and stretching. It never breaks.

[narrator] Over nine months of pregnancy, the cervix gets five times stretchier.

子宮頸就是把子宮關起來的關鍵

When it's soft like the skin on your lips, it opens up.

Oh! I'm sitting here in a puddle of water.

Oh, that's cool. We got another one here in the fridge.

this very compliant material has to remodel and repair itself.

I don't know of any other engineering material

that can soften or remodel itself that quickly.

the cervix is an anatomical and engineering miracle.

But that doesn't make childbirth itself any less daunting.

I'm not really scared. I'm, like... Yeah, I am nervous.

[laughs] I'm completely nervous, like, but it's only

because this is my first kid, so I don't really know what to expect.

[narrator] Around the world, 250 babies are born every minute.

能夠如此迅速的自行軟化和改造

簡單來說 子宮頸是解剖學和工程奇蹟

不過生產過程並不會因此而輕鬆

[doctor] Sweetheart, show me what you got. Ready? Nice deep breath in.

Breath. And push from your bottom. You got this.

[narrator] But childbirth still kills  more than 800 women every day

to 30% of women rate childbirth as traumatic.

I just remember, like, closing my eyes and going inside

to just be like, "I have to get through this."

讓我看一下，準備好了嗎？深呼吸

I was, like, really traumatized for a really long time.

[narrator] So, what makes childbirth so hard?

And what can women do to have the easiest and safest experience?

世界上每天有八百名婦女因生產而死

[narrator 2] The contractions in true labor

才能告訴自己：“我要把孩子生下來”

how the baby can possibly get through that small opening.

女人該怎麼做 才能有最簡單及安全的體驗？

[man]  It is not only pathological knowledge

One that does not let you forget you have in your hands the lives of two people.

嬰兒怎麼可能經過這麼小的開口

[narrator] Most large primates give birth in relatively similar fashion.

The female carries the fetus in her womb for 30 to 40 weeks,

and then the baby emerges from the birth canal,

多數大型靈長類的生產方式極為相似

like some Monty Python sketch, for non-human primates.

女性的胎兒會在子宮裡待上30至40週

they have a seemingly much more easy childbirth

通常頭先出來，要花上幾個小時

[narrator] Humans labor around nine hours the first time they give birth

嬰兒不會像蒙提派森的喜劇那樣

while most chimps labor for just two hours.

And there's one part of the struggle of childbirth

[woman 1] It felt like the bottom half of my body was gonna explode

and erupt goo all over the four walls of the room.

人類第一次分娩要花上大約九個小時

[woman 2] Like you're in some kind of pain blender,

大部分黑猩猩分娩只要兩個小時

and you don't know what's going on. It feels like you're being ripped in two.

and there's, like, this alarm that's like... [imitates siren]

[woman 4] It looked like I was experiencing an exorcism.

[narrator] The question of why humans have painful births comes down

Humans, unlike other primates, evolved to walk on two legs,

which meant pelvises became more complicated and narrow.

Our brains also evolved to be bigger than other primates',

{\an8}So chimps get to push out a small head from wide hips,
