If humans ever want to live permanently in space, they will need to make sure they and any farm animals they bring with them can reproduce, said study senior author Teruhiko Wakayama, a reproductive biologist at the University of Yamanashi in Kofu, Japan, and his colleagues.
However, outer space is dangerous. For instance, the average daily radiation dose on the International Space Station (ISS) is more than 100 times higher than that on Earth, and could damage the sperm and eggs that give rise to most animal offspring, the researchers said.
To examine the damage that space radiation could do to potential animal offspring, the researchers shipped samples of freeze-dried mouse sperm into space. (Freeze-drying preserves items by rapidly freezing them and then subjecting them to a high vacuum that dehydrates them. Freeze-dried ice cream is often known as "astronaut ice cream.")
This mouse sperm was stored on the ISS for 288 days, from August 2013 to May 2014, at temperatures of minus 139 degrees Fahrenheit (minus 95 degrees Celsius). The sperm was then returned to Earth and compared with freeze-dried samples that were preserved on Earth during the same time under similar conditions.
The researchers found evidence that space-preserved sperm did experience slightly more DNA damage than Earth-preserved samples.
"This was a little bit surprising, because the storage period was only nine months," Wakayama told Space.com.

Mice cubes?
Waiting for the ‘First wise guy to point researchers to his wife for a good place to find frozen sperm’ ping...
Cold as Ice
Foreigner
You’re as cold as ice
You’re willing to sacrifice our love
You never take advice
Someday you’ll pay the price, I know
I’ve seen it before
It happens all the time
Closing the door
You leave the world behind
You’re digging for gold
Yet throwing away
A fortune in feelings
But someday you’ll pay
You’re as cold as ice
You’re willing to sacrifice our love
You want paradise
But someday you’ll pay the price, I know
I’ve seen it before
It happens all the time
Closing the door
You leave the world behind
You’re digging for gold
Yet throwing away
A fortune in feelings
But someday you’ll pay
You know that you are
(Cold, cold) (as, as) (ice)
As cold as ice to me
(Cold, cold, cold) (as, as, as) (ice)
You’re as
Mice pubes.............
Freeze-Dried Space Sperm sounds like a good name for a band that would hit the scene for about 18 months, put out one CD, then fizzle away in Ft. Collins or Boulder.
I miss the earth so much
I miss my wife
It’s lonely out in space
On such a timeless flight
...
Mars ain’t the kind of place
To raise your kids
In fact, it’s cold as hell
And there’s no one there to raise them
If you did
Great news for mice.
Abstract: Mouse Balls Available as FRU (Field Replacement Unit)
Mouse balls are now available as FRU. Therefore, if a mouse fails to operate or should it perform erratically, it may need a ball replacement. Because of the delicate nature of this procedure, replacement of mouse balls should only be attempted by properly trained personnel.
Before proceeding, determine the type of mouse balls by examining the underside of the mouse. Domestic balls will be larger and harder than foreign balls. Ball removal procedures differ depending upon manufacturer of the mouse. Foreign balls can be replaced using the pop-off method. Domestic balls are replaced using the twist-off method. Mouse balls are not usually static sensitive. However, excessive handling can result in sudden discharge. Upon completion of ball replacement, the mouse may be used immediately.
It is recommended that each replacer have a pair of spare balls for maintaining optimum customer satisfaction, and that any customer missing his balls should suspect local personnel of removing these necessary items.
To re-order, specify one of the following:
P/N 33F8462 - Domestic Mouse Balls
P/N 33F8461 - Foreign Mouse Balls

This raises many interesting questions...

Ground Control to Major Tom
Ground Control to Major Tom
Take your protein pills and put your helmet on
Ground Control to Major Tom (ten, nine, eight, seven, six)
Commencing countdown, engines on (five, four, three)
Check ignition and may God’s love be with you (two, one, liftoff)
This is Ground Control to Major Tom
You’ve really made the grade
And the papers want to know whose shirts you wear
Now it’s time to leave the capsule if you dare
“This is Major Tom to Ground Control
I’m stepping through the door
And I’m floating in a most peculiar way
And the stars look very different today
For here
Am I sitting in a tin can
Far above the world
Planet Earth is blue
And there’s nothing I can do
Though I’m past one hundred thousand miles
I’m feeling very still
And I think my spaceship knows which way to go
Tell my wife I love her very much she knows
Ground Control to Major Tom
Your circuit’s dead, there’s something wrong
Can you hear me, Major Tom?
Can you hear me, Major Tom?
Can you hear me, Major Tom?
Can you “Here am I floating ‘round my tin can
Far above the moon
Planet Earth is blue
And there’s nothing I can do”

Heck, at this point even mouse balls would be better than what the GOP is currently wielding.

How appropriate, a researcher named Wakayama doing a study on sperm.
.... you are very detail oriented
If this works out for humans they can update that classic Star Trek opening. Change it from “to boldly go where no man has gone before.” To: “To boldly c....”
No, even I can’t stoop that low.
