Scientists tested how human sperm behave in microgravity by placing them in a chamber that mimics the female reproductive tract. They found that in low-gravity conditions, sperm had trouble navigating and were more likely to lose direction compared to normal conditions on Earth. This reduced their ability to reach an egg. Experiments with mouse eggs showed a similar effect: fertilization rates dropped by about 30 percent over four hours in microgravity.
These findings, published in *Communications Biology*, are important as space agencies plan long-term missions to the Moon and Mars, where humans may eventually want to reproduce. The study suggests that microgravity could make natural fertilization more difficult, raising challenges for future space travel.
Researchers also tested progesterone, a hormone released by cells surrounding the egg that normally helps guide sperm. In the experiment, adding progesterone improved the sperm’s ability to orient themselves even in microgravity. However, this effect only occurred at much higher levels than are naturally found in the body, meaning it is not yet a practical solution.

It was probably just carrying a Y chromosome, so it refused to stop and ask for directions
Edit: more scientifically accurate phrasing of joke
As if the ISS isn’t filthy enough already
Interesting space porn
Sounds to me like the 250 mile high club just got more exciting.
So sex in 0 G is another contraceptive but only decreases the chance by 30%.
Just chuck the woman in [this invention](https://youtu.be/AFNmwFpyB3E?) I did a thing made the other day. Should simulate gravity well enough.
This is why everyone in Star Wars and Star Trek looks almost human
Interesting 🤔
Who needs contraception when you can just fuck in space?
> placing them in a chamber that mimics the female reproductive tract
Most professional way to say you gave an astronaut a fleshlite
But what we really want to know is…if you nut in space, does it push you backward?
In theory if we could colonize the moon and mars wouldn’t it be easier to just lab grow children? Like why would you want natural conception when you can avoid all the unpleasant experiences?
Panspermia people. This is how life started in the universe. Ancient aliens gooning in spaceÂ
Oh okay well, in order to make science happen I think I have to test the effects of space on me doing nothing and just chill out in space. These important and totally not bullshit reasons to do this will be published as someday humans will eventually want to fuck off and do nothing in space.
We cum in peace 💦
The world is collapsing and we’re wasting money to study sperm motility in outer space. Wtf. Well I guess it’s because the world is indeed collapsing
I’ve seen this experiment in the start of a movie.
Fun fact, my parents rented it because it sounded innocuous enough, I mean “Look who’s talking” with a cute baby on the front, sounds like a kids movie to me.
Sometimes science goes too far
Well now someone is gonna write fan fiction about the astronaut who gets pregnant in space while her husband is at home. He thinks she cheated with the male astronaut she was stationed with. Turns out it was space splooge.
Where did they get viable sperm for the test?
I just wanna know who got paid to crank it in the shuttle.
Am I understanding that zero gravity is a contraceptive albeit a poorly effective one lol
If we ever were making generational ships we’d need simulated gravity areas anyway so they would just be play rooms too
A small fap for men.. A giant leap for mankind.
