“Exposure to short duration gravity load changes including microgravity, as sustained in a parabolic flight statistically significantly decreases the sperm motility and vitality of human fresh sperm samples,” the team found, adding that this may have huge importance for any prolonged human settlement missions in space.
“In the future, should humans remain in space for long periods of time with exposure to different microgravity and hypergravity peaks, which could range from months to a number of years, reproduction may pose a problem to be tackled.”
The mechanism by which sperm motility was decreased remains unknown, with further study needed.

Who’d have thought a headline could contain all those words
I’m dyslexic and for a moment I was like. Why would you take people who work on boats on the vomit comet? Is it to see if their sealegs transfer to space?
ᕕ( ᐛ )ᕗ disorders can be fun sometimes…
Ps. Someone should do that study I mentioned.
After sparing this paper a fair bit of attention I feel I’ve wasted it.
Nowhere in the paper could i find in what conditions the test samples were kept during the experiment. This is pretty basic stuff. At this stage I’d wage sloshing was the issue.
Reading this part of the methodology:
"2.2 Initial sperm analysis
After liquefaction…
[Two paragraphs later, in the same section: ] After this first analysis, the 15 sperm samples were split into two fractions. All the samples were exposed to ‘Parabolic flight’ (split 1) and to…"
Did they liquefied the samples and tested like that? Whaa?
The “After this first analysis” should not be in the “2.2 Initial sperm analysis”. It just shouldn’t!
Then I think “15 sperm samples were split into two fractions”. … “the samples were exposed to ‘Parabolic flight’ (split 1)” — splits, fractions, what a mess!! At this stage I’ve wasted enough.
The paper should be retracted, the reviewers spanked and the editor fired.
the reviewers spanked
likely not much of a punishment for these perverts
Sloshing? On a vomit comet? Naw…
I find it very hard to believe this hasn’t been tested on the ISS.
Called it
Everything experiences zero g on the ISS. How would you test this there?
You can collect sperm samples in space, too.
Exposure to short duration gravity load changes
Thats what the reduction in “motility and vitality” comes from. There is no way to create those conditions on the ISS so there is no point in considering the ISS for testing this.
The astronauts in the space station didn’t teleport there.
Literally (fiction) speaking, I’ve randomly gambled on ~10 generations max before the population crashes if a generation ship arrives and fails to complete an O’Neill cylinder on the other side.
Sound legit? 4am, going to bed, so no read.
Don’t worry I didn’t even see it until now

Imagine turning on a black light inside the Vomit/Semen Comet.
Can we please stop pretending that future space colonists will live their whole lives in microgravity? Nobody seriously suggests that as an option, that’s stupid. Countless studies have shown that for proper biological development, humans (and in fact nearly all organisms) need gravity. But for large space stations, spin gravity is actually not that freaking hard. If you can create a large enough station to support a sizable colony, it does not take much more engineering to make it spin.
Jokes on you, that’s my kink
Wait, how is this a thing? Were they -ahem- draining the men before the flights…?
Wank in a cup pre flight and wank in a cup after.
You’d also need to repeat the experiment as a control (ideally still doing as much of the same things to account for other variables). For best accuracy you’d need the same group returning another day, going through the same boarding process without takeoff, and tracking the exact time between wanks.

Assistant to the Post Flight Fluffer!
Probably pays pretry good.
I would unironically enjoy my job if i made 150k+ a year just to jack off men for science

Why is creating more humans a good thing in a world with all this suffering?
They are literally only talking about creating humans NOT on this world…
Not this planet, this universe
The universe has plenty of room for more humans. There’s a shit ton of matter out there, if you can get to it.
No, I meant to say by there being suffering in the world, I meant in the universe, rather than specifically referring to this planet and there would be no human suffering in off Earth colonies.
… Why not just say that then? It would save much confusion.
It’d be hard to say whether there would be no suffering in off-world colonies, but I should doubt it. Traditionally, colonisation has been a dangerous thing, and human nature is as human nature does. The best you can do is reduce it so that what suffering does occur is either minor, or ineffectual.
Today I seem really terrible at saying what I mean! 🤣
Whether on or off planet, humans anywhere will experience suffering, likely to an extent that far outweighs the pleasure they experience. Therefore it’s unethical to create more humans if your goal is reduction of suffering.
All life lives. Not just humans.
Most of us aren’t suffering and spending time with my kids is amazing and I enioy it.
Lol the downvotes are killing me.
“Fuck you for enjoying your life and family!”
I get you. But that’s life. Life wants to live and create more life. That’s what it’s about. The parts of life that ask why will be set aside and not used for the continuation of life.
