Can humans have children in the universe?

Dr. Yi Deer Brock, a fertility expert, said that by 20031year, pregnant women who intend to participate in the space delivery program will be able to experience a 24-36-hour space journey and give birth to their first space baby on a spacecraft in low earth orbit 2000 kilometers away from the Earth.

Dr. Yi Deer Brock said that due to many uncertainties in space travel, the space transportation plan will not only serve one woman, but as many as 30 women will participate together. Experts believe that the average risk of space delivery project is lower than that of western-style delivery on earth.

And the famous Russian scientist Irina? Dr Irina Ognieva said? We have always been ahead in space projects, and we also hope that the first person born in space will be a Russian citizen. ?

Ogneva not only wants Russians to give birth in space, but also wants Russians to reproduce in space, thus giving birth to a 100% space baby. To this end, Ognieva conducted a space sperm collection experiment. They want to get their semen samples before astronauts enter the International Space Station, during the space station and after returning from the space station, so as to analyze the influence of the time spent in space on sperm quality.

Because on the International Space Station, the radiation received by people is 100 times that of the earth. As the most sensitive part of the body, the lower body organs bear the brunt. Radiation can cause serious reproductive problems of sperm.

In addition, space microgravity will have lasting negative effects on human body, including sensory nervous system disorder, head-to-head distribution of body fluids, cardiovascular system dysfunction, muscle atrophy, bone loss and psychological problems.

Before this, scientists have studied the influence of the cosmic environment on biological reproduction. Various animals were tested in different experiments, including mice, fish, salamanders and even sea urchins. China tried to take more than 6,000 mouse embryos into space. He wanted to know whether these embryos could develop normally as they did on the earth after being affected by the space environment, thus indirectly predicting whether human beings could reproduce in space in the future. These embryos successfully developed into blastocysts in space, which is basically the same as the time on the ground.

But human beings are different from mice after all, so whether human beings can reproduce in space needs a series of evaluations, which is also the purpose of Ognieva's experiment.

However, Ogneva's experiment has been rejected by astronauts. The reason for the refusal is not that astronauts don't cooperate, but that it is difficult to obtain sperm in space environment.

Due to low blood pressure and Qi Bo deficiency caused by weightlessness, not only that, the lower body organs will even shrink.

Moreover, in the microgravity environment, if the liquid is not bound by a container, it will form a water balloon floating in the air. It will be difficult to collect. If you don't pay attention when starting, the liquid will float in the air with the astronauts, which will be very embarrassing for Xin.

Water in space will stick to your hands and will not flow.

Most importantly, in space, men's testosterone levels will drop sharply. Simply put, once an astronaut enters space, he will enter because of the decrease of testosterone level? Sage mode? .

All these reasons caused Ogneva to be unable to obtain sperm from the space environment, which led to the failure of the experiment. I believe Ognieva can find a solution to this problem.

How to reproduce in space has always been an important obstacle for human beings to immigrate into space. Scientists are now thinking about whether to combine men and women like the earth, or to preserve sperm by other technologies and cultivate the next generation in a suitable radiation-free environment.

For example, Japanese scientists proposed to use freeze-drying technology to solve the problem of human space migration. The sperm was obtained by freeze-drying technology and the sample was freeze-dried. Freeze-drying technology is to quickly place biological samples at a low temperature below zero, freeze them into solids after cooling, and then sublimate solid water directly under vacuum. This technique can quickly preserve samples while maintaining the activity of macromolecules, such as DNA and protein.

Such a portable sperm bank can help us to quickly replicate life on earth on a newly discovered planet in the future cosmic era.

No matter what kind of plan scientists put forward, it is for human beings to reproduce in space. After all, if the earth people go to other planets, if they can't reproduce, then it seems meaningless for the whole human race to immigrate to other planets.
