Sex in in outer space could be deadly, according to a new study from the University of Montreal.
Researchers studying the reproductive processes of plant cells found that gravitational changes could compromise the development of human offspring conceived during space travel, The Daily Mail reported. Scientists believe that cell behavior evolved under the force of Earth’s gravity.
The study, which was published in the peer-reviewed scientific journal PLOS One, tested only plant cells, but human and plant cells transfer sperm similarly during reproduction.
“Intracellular transport processes are particularly sensitive to disturbance, with dramatic consequences for cell functioning,” said Montreal University biologist Dr. Anja Geitmann, the study’s lead scientist.
The researchers noted that those consequences could include the development of cancer and Alzheimer’s disease.
Sex in space has been a subject of curiosity and speculation for years, but NASA denies that its astronauts have conducted any of their own experiments to look into the topic.
