Can conception, pregnancy and childbirth in space?

Breeding offspring is an important way for the earth’s biological continues to grow population. However, today’s scientific research shows that the earth will not adapt to biological survival. In the futureIt becomes no longer suitable for the survival of Earth creatures and human beings.

In order to continue human civilization, we must carry out space immigrants. However, in order to achieve space immigrants, we still need to verify whether creatures can mate, conceive, birth, and survive in space.To this end, scientists conducted a series of scientific experiments.

In order to verify whether creatures can mate in space, in 1994, Japanese scientists brought cymbals to space.This is because the fish belongs to in vitro fertilization. They will produce eggs and sperm in the outside world, which is more convenient for researchers to observe and verify whether they are pregnant.It was found that not only could they lay normally, but they also successfully hatched 8 small fish in space, and when they were reproduced to the third generation, the offspring was completely normal.

Although blue catfish can lay eggs normally in space, it is difficult for other creatures. After all, the reproductive method adopted by most animals is: conception in the body.In order to verify whether mammals in space can conceive, scientists have launched a space mouse pregnancy experiment in space.

In 1979, a pair of rats lived in space for 18.5 days, and found that they did not successfully mate during this period, and even refused to have a relationship.What you know is that rats on the earth are not abstinence, and they always seize all opportunities to conceive and give birth to future generations.

Later, the researchers conducted many rats in the space breeding experiments in space, and found that compared to rats living on the earth, the propagation power of rats in a micro -gravity state is low.There is a series of issues.

For example: In 1995, American scientists asked mice to get pregnant in space. As a result, there were problems with the stress of gravity sensing in the newborn cubs. They could not turn over by themselves, and mice on the earth could do it.

Later, scientists mated mice born in space with female mice on the planet, and found that the mice born of the mice born were stunted and organ was abnormal.

Since the fertilization rate of living animals is low and the offspring is prone to adverse gene mutations, the mouse’s sperm is placed in space, and then the in vitro fertilization embryo is transplanted into the mouse body. Will the mice develop successful?

In 2013, scientists frozen some mice sperm and put them into the International Space Station. After 9 months, they brought these sperm back to the earth. After that, they were fertilized by these sperm and mouse eggs.Similar, and the bred mice can still breed offspring normally.

We know that the reason why researchers have launched so many animal space experiments in space is to test whether humans can mate, conceive, and give birth to healthy offspring in space.

According to humans’ observations of mice mating, it is found that female mice will decrease or even disappear when they are in space, which will lead to abortion.If human women will be the same in space, then human women will be difficult to breed offspring in space. Even if the conception is successful, the abortion rate will be significantly greater than the earth.

It is said that the United States had performed a human space mating experiment in space, but it was not officially recognized.But they did conduct a human sperm experiment.In an experiment called Micro-11, researchers collected sperm from 12 healthy men, then placed them in the International Space Station, and used chemical signals to simulate eggs to seduce sperm swimming.It was found that due to the lack of gravity, it seemed to make sperm movement faster.

In addition, it is very difficult for humans to mate according to the micro -gravity environment of space. This is because sperm also belongs to liquid, and liquid will flutter uncontrollably in a heavy environment, which will hinder human conception.

However, at this stage, it is difficult for us to conduct space human conception experiments. This is because any experiments involved in human beings, especially the baby’s experiments, must be scrutinized by rigorous ethical and moral censorship. At presentThe experiment after 14 days will be stopped.This is to avoid the birth of the baby with various experimental purposes, thereby losing human rights.

At this stage, through various experiments, some creatures have been verified by some creatures that can be born in space, but mammals are difficult to conceive in space. Even if conception is successful, pregnancy and childbirth are also a problem, especially human babies, because human babies are headed by human babies heads, because human babies are headed by human babies heads.Large dimensions are a problem even if giving birth on the earth, let alone in space.

In other words, scientists still have a long way to go to how humans have children in space immigrants in the future.
