Male astronauts can be replaced by sperm banks in space, while the crews of all women conquer the galaxy, armed with everything they need to populate distant colonies, scientists say
- Frozen sperm can be transported to create a human sperm bank outside the earth
- Male astronauts can then be replaced by teams for women only, scientists say
- Further work is needed to fully understand the effect of space conditions
Women could be sent to space with a selection of sperm cells ready to populate other planets, researchers say, testing the effects of zero-gravity on sperm.
Frozen semen can be transported to the space to open & # 39; the opportunity to create a human sperm bank outside the earth & # 39 ;, say researchers from the Dexeus women's health center in Barcelona.
This may mean that male astronauts are being replaced by teams for all women to reproduce in space.

But further work is needed to fully understand the effect of space conditions and different levels of gravity.
Frozen samples that have been exposed to microgravity and that are kept on the ground all seem to stay healthy, the researchers say.
The research was presented at the annual meeting of the European Society of Human Reproduction and Embryology in Vienna, Austria.
It is after NASA published an article arguing that single-sex mediators are the best for cohesion and that women are rather cooperative.
Dr. Montserrat Boada, of Dexeus Women & # 39; s Health in Barcelona, said: & # 39; Some studies suggest a significant decrease in the motility of human fresh sperm steel.
& # 39; But nothing has been reported about the potential effects of gravity differences on frozen human gametes, in which state they can be transported from Earth to space.
& # 39; It is not unreasonable to start thinking about the possibility of reproduction outside the earth. & # 39;
The researchers used sperm from ten healthy donors, some of the samples being exposed to microgravity by repeatedly flying in a steep arc in a small acrobatic aircraft.

The samples were then analyzed for concentration, motility and DNA fragmentation – tests that are all performed to check fertility.
No significant differences were found between the samples on the ground and those exposed to micro gravity, according to the study.
& # 39; The lack of differences in sperm characteristics between frozen micro-gravity samples and those maintained in soil conditions opens up the possibility of safely transporting male gametes to space and considering the possibility of moving a human sperm bank outside the Earth & # 39 ;, the researchers said. .
However, they added that this is a preliminary study and that they should validate their findings with more samples and expose the sperm to room-like conditions for a longer period of time.
& # 39; Our best option will be to perform the experiment with real space flights, but access is very limited & # 39 ;, said Dr. Boada.
