AIBU to think a foetus is alive before birth?

I had a discussion with someone, who believes that a foetus is not alive, until the point they are born. They also asserted that this was not an uncommon view. I have a hard time believing this so I'm putting it to the AIBU poll.

To be clear, I'm pro choice, but I do believe that, for example, a 30 week foetus is factually, scientifically considered to be alive.

Surely, even if you're pro-choice all the way up until birth, you accept that the foetus is alive?

YABU = A foetus is not alive, until birth.
YANBU = A foetus is alive in the womb.

Of course a foetus is alive. That is a completely different question to whether you think it is or should be a legal person (which I do).

How would a foetus being a legal person work though - what stage would you have it?

because whilst a foetus is alive it isn’t independently so and you would have to decide when

I can’t believe anyone - especially a woman who’s been pregnant! - haven’t they felt the baby kicking - can believe that a baby’s only alive once it’s born!

TBH I’d assume that they are just plain thick - and/or have been reading all sorts of rubbish on dross-type social media.

Yes sorry same here. Got to be incredibly thick to think a baby isn’t alive whislt in the womb.

@GertrudePerkinsPaperyThing

I would say a foetus is alive from the moment of its creation. Whether someone would consider it a 'human life' at that point is up to them. In the absence of abortion or miscarriage, it's going to develop into a human life, so it seems reasonable to call it a human life from the beginning.

But even if it's not considered a human life, it's still a living entity from the moment of conception.

I think PP has a point that it's difficult to pinpoint though. You would say it's alive from the moment of its creation but science hadn't actually figured out a way to detect or determine the exact point of conception yet so it's a bit like the analogy of the tree in the woods -is alive until anyone knows it there? If it's conceived and miscarried earlier than a women even knew she was pregnant, was it alive in the same way as a life or in the same way as other cells are "alive"? Likewise saying in the absence of abortion is a massive IF. Whenever conception happens theres a million if, if, if between the point it's a few cells and developing into a. Human life, and such a large proportion don't go on to develop into that human life. It's so vague and unknown that everyone's going to have their own personal opinion.

I think it’s one of those million dollar questions - when does life begin!

I mean I think most sensible people can agree a foetus isn’t a human life at, say, 2 weeks. And is one at 38 weeks.

But where in between those two life begins is difficult to pin point! And then why is it different if the foetus will have disabilities?

Thats why, in my view, we have to leave a large amount of choice up to the woman - we’ve currently drawn one line after which she no longer gets a choice in this country, but it’s somewhat arbitrary.

The point when the foetus could potentially survive outside of its mother’s body is the best estimate we can come up with, I guess.

No I don’t think that. I don’t know a great deal about the subject but by awareness I mean conscious thought. I understand that a foetus responds to stimulus but that conscious thought is unlikely to be present before 24-28 weeks depending on development. In my layman terms I classed that as alive but not aware.

But they still feel pain as the nerves are developed before birth. How can they be unaware? What do you think happens at birth that would make them conscious and suddenly aware? That doesn’t make any sense

firstofallimadelight · 20/03/2026 05:12

A foetus is a part of the women carrying it so is alive by default. Once a foetus is able to be separated from its mother it becomes a baby and is alive in its own right.

Thanks, @Babyboomtastic and @Mmmchocolatebuttons. I clearly missed a couple of the more outré replies in the other thread. Thinking back, I may have scrolled past the one about a death certificate - one poster said nobody holds a funeral for a miscarriage and I moved swiftly on, shaking my head and muttering "They do!"

Yes, the death certificate post was a weird one!

I voted YABU because I was on the FWR thread and have read all the opinions. You've misrepresented the debate, @Mmmchocolatebuttons.

Nobody said a thriving foetus is dead.

They've said, in various ways, that a biologically 'living' thing is not necessarily a 'person' or may be considered to have a right to life if its mother chooses to stop incubating it.

To put this more brutally, a foetus is parasitical. Parasites typically belong to another species, which doesn't apply here, but it is true that the foetus is dependent on the woman's resources and will die without them. It even alters the woman's body, as parasites do to their hosts.

We're entitled to choose what lives in our bodies.

I haven't misrepresented the debate. The person I was arguing with did not mention anything about personhood.

I fully accept everything you've said.

So I suppose if you can convince people that babies in the womb are 'unalive' you might be able to gather more support for termination to term? Is that the angle activists are going for maybe? Kind of like the 'bunch of cells' argument worked to legitimise termination to 12 weeks, and then 'viability' legitimised termination to 24.

ZoeCM · 19/03/2026 23:19

Of course a foetus is alive. And of course abortion involves killing it. Crazy to say otherwise.

The issue is personhood. Is a foetus a person before 20 weeks or so? I wouldn't say so. It's human, but not a person.

giddyboo · 19/03/2026 22:45

If it wasn't alive then they wouldn't have to terminate its life. There wouldn't be any need to stop its heartbeat when its at a longer gestation before the pregnancy is induced to terminate.

HelenaWaiting · 19/03/2026 22:32

I voted YABU for your goady thread.

Thelnebriati · 19/03/2026 22:26

Of course a foetus is alive when its developing in the womb. But its not capable of staying alive independently.
Its not a person until it has separated from the mother and drawn breath.

Zippymonkey · 19/03/2026 22:03

Crofthead · 19/03/2026 20:01

So do you think the nerves become ‘activated’ at birth?

No I don’t think that. I don’t know a great deal about the subject but by awareness I mean conscious thought. I understand that a foetus responds to stimulus but that conscious thought is unlikely to be present before 24-28 weeks depending on development. In my layman terms I classed that as alive but not aware.

Hemsfa · 19/03/2026 21:50

Course it's alive. I won't bother on having an abortion debate on here at all though. Just turns into nastyness and getting banned.

There's been zero misrepresentation. One of the tangent that thread went off on is that you can't kill a fetus because it's not something that's alive in the first place. When asked further about this, a couple of posters doubled down on this concept that a fetus is not a living organism until it is born. This has nothing to do with its worth, or the moralities of the abortion debate, but whether it was actually a living organism.

Rather than derail the thread more on this interesting side issue (which frankly only has tangential links to abortion), the poster sensibly started a fresh discussion.

It was also suggested that in order for something to be alive, it would need to have a death certificate to say when it's dead, which means no other animal or plant on this planet is alive by that definition.

It's entirely possible to (erroneously) believe a fetus isn't alive and be anti abortion. It's also possible for someone to agree that it's alive, but that due to women's rights being the primary factor be ok with abortion.

HeyThereDelila · 19/03/2026 21:40

A foetus is alive from conception.

I’m pro choice but pretending that a baby at full term isn’t alive is ludicrous.

But babies can't survive independently either. They rely on someone to feed them, keep them warm, looks after them etc.

They don’t rely on another body to survive though. A baby can live separately from a woman whereas a fetus can’t.

Or psychological reasons. I don't think whether a foetus is alive is the primary consideration. The mother's autonomy of choice and wellbeing is paramount.

Psychological would come under medical

It's a weird question.

An unborn baby is classes as a parasite, it surpresses the immune system and takes what it needs from your body.

A tapeworm does similar. Is that alive?

You're either alive or you're not.

What you're asking is do unborn babies have any rights to go on living outside the body. Not whether it's alive or not.

No, she's merely asking if it's alive. It's been argued that it's not a living organism at all, which frankly doesn't stand up to science or common sense.

They start to feel pain between 24 and 28 weeks gestation.

Yes I was quoting the person who said they were not aware
