Due to cosmic radiation attacking the human body, sexual reproduction in outer space is impossible, according to scientists from the American space agency NASA. From the Ames Research Center in California, they found that without effective protection of the spacecraft, there is a possibility that powerful proton particles would sterilize any female embryo. . Scientists note that space technologies are not yet advanced enough to offer sufficient protection from this type of radiation. Experts also come to the conclusion that the particles also affect men’s reproductive abilities by damaging the quality of sperm. Given that travel to distant planets would likely take decades or centuries, this could render any colonization mission a failure. DNA, which governs the development of all cells in the body, is particularly susceptible to the radiation that abounds in outer space, explain the scientists. Research on animals shows that exposure to ionizing radiation destroys eggs – which are generally laid already in embryonic development in girls – by the end of the second – beginning of the third trimester of pregnancy. The research was published in the journal “Journal of Cosmology “.
