Paracetamol in pregnancy changes daughters uterus and ovaries.

[Imdunfer]

I think this new research isn't being widely reported. It would worry me, sorry if it worries anyone else, and what's done is done and can't be changed, but I think pregnant women probably need to know.

Sorry if it's been reported already. Tylenol/acetaminophen is paracetamol.

This is behind a paywall. What would be more helpful is if you posted a link to the peer reviewed scientific study that supposedly proves this rather than a vague scare mongering news article. Worse an article from a country that believes Tylenol (paracetamol) causes autism....

It’s a Danish study https://academic.oup.com/hropen/article/2026/3/hoag073/8787665

It wouldn’t overly worry me. If I was taking paracetamol it would be for a fever, which is also not great in pregnancy.

It is also clear in the study that they don’t know whether these differences seen in girls have any effect on fertility.

I'm sorry it's not behind a paywall for me. All you have to do is give them your email address and you get a certain number of articles for free. It's Reuters, trustworthy.

The USA does not believe paracetamol causes autism and has produced plenty of research that shows it doesn't.

Reuters is an international news agency and the source of most of what you read in the papers, they all take the same feed.

Did you think of googling the research yourself before accusing me of scaremongering?

Thank you for the pointer.

Unfortunately under Trump the USA does appear to believe there’s a link, and held a press conference saying exactly that earlier this year.

Did you read the article you pointed to? It says nothing of the kind, quite the reverse in fact.

I think we all know by now that Trump and some other dumb right wingers believe it. "The USA" and particularly the USA scientific community do not.

And it has zero relevance to a Danish study about uterus and ovary size and egg numbers in female children.

It's an observational cohort study which only follows the girls to adolescence. Plus no randomisation of subjects and all the other usual limitations of OCS as a form of research.. 'Further research is needed to determine whether these early-life differences have consequences for reproductive health later in life' - the study says so itself. So it shouldn't worry you. And it's disappointing to see it posted in Mumsnet with the instruction that 'pregnant women need to know'.

It’s a single small study (302 infants) and they’re unsure of the significance of the findings. Paracetamol is one of the few options for pain relief in pregnancy so I’m not sure it should dramatically change women’s behaviour at this point.

This is an early study suggesting some minor differences. if much more study is done and a clear understanding of the potential long-term risks to girls is found, THEN I will start to worry about it. In th emeantime, I'll continue to assume that as the vast bulk of women who want to have children are, in fact, able to do so in due course, that their mother's use of paracetomol in pregnancy did not negatively impact them.

I'm not anti research on thee things. But I am very tied of research, almost always reseach that seems to suggest WOMEN ned to do things differently (pregnancy or not) where the findings are vague, unsubstantiated and not particularly detailed. And almost NEVER with suggestions for what to do to support.

I know what it says; I was referring to what Trump says.
