Laut einer neuen internationalen Studie sind Männer zum ersten Mal in der Geschichte der Menschheit weniger fruchtbar als Frauen. Der Wandel hat weltweit zu unterschiedlichen Zeiten stattgefunden und ist eine Folge des wachsenden Anteils von Männern in der Bevölkerung

> The researchers examined whether men or women have fewer children and show that demographic imbalances around the world – in particular, a growing share of men – are affecting men’s fertility.
> Our main findings point to a historical turning point, from higher fertility among men to higher fertility among women. This shift occurred globally in 2024. The change is driven by an increase in the proportion of men in the population, explains Skirbekk.
> the researchers highlight long-term global trends, including rising numbers of sex-selective abortions in some countries – where girls are not carried to term – lower mortality among men, and the fact that significantly more boys than girls are now being born each year.
> Historically, the surplus of men tended to disappear before they reached reproductive age. That is no longer the case, elaborates Skirbekk.
>In Oceania, South America and Asia, this transition has only taken place recently. In sub-Saharan Africa, it is unlikely that we will see a shift from higher male fertility to higher female fertility before 2100, as the decline in fertility has now stalled while mortality remains high, according to the researchers.

It’s crazy how the solution to so many issues are –
1. Strengthen women’s position in society
2. Invest in education
3. Provide social opportunities
EDIT – it’s a really short article, just give it a quick read if you’re gonna comment, innit.
On a pure anecdotal basis i thought number of girls were increasing. Cos everyone around me is having girls.Apparently not
> The researchers highlight … lower mortality among men
It sounds like the underlying trend is that young men used to die at far higher rates than they do today.
How is it even possible to tell whether in history such a situation occurred or not? Moreover, on what basis are these assumptions made? Do they test everybody on earth, by working with medical statistics and records of patients of specialized doctors?
This forced birth thing is really working out for them…

Really important for laypeople to understand that what they are talking about here is not men’s *fecundity* (their ability to have children, sperm count, etc).
What they are talking about is men’s fertility (the actual number of children they have produced).
In overpopulation, you expect to see decreasing fertility rates (AKA: births). What you don’t want to see are decreases in fecundity rates (the ability to repopulate).
Last I checked each op has a 1:1 ratio, so doesn’t this basically mean they be stacking up baby daddies
I don’t get why this is about fertility at all. It’s just an effect of demographic sex distribution. Every child is produced by a male and a female, so if there are more of one sex, their fertility has to be lower on average.
Oh nice – time to start screeching from the rooftops about how their value is tied to their youth.
I’m kidding. Please for the love of god I am just joking
How does that even make sense as a measurement? That just seems like a needlessly complicated way of saying „there are more men than women now.“
I hate the use of „fertile“ to mean offspring produced, and not the quality of gametes. Especially because male sperm quality is decreasing.
A person could be extremely fertile and never reproduce.
It’s just a confusing way to phrase it, one is a biological problem, the other is a sociological observation
