It seems that there is hope for reproduction for the human populace in outer space. A small preliminary study by Spanish scientists have found out that frozen sperm samples are still viable after exposure to simulated space flight. CNN has more details:
The small preliminary study, presented at the European Society of Human Reproduction and Embryology in Vienna which began Sunday, exposed human sperm samples to microgravity.
Dr. Montserrat Boada from Dexeus Women's Health in Barcelona, who presented the results, stressed the study was only preliminary and would require further work.
The team will now move on to larger sperm samples, longer periods of microgravity, and using fresh rather than frozen sperm, she said.
"If the number of space missions increases in the coming years, and are of longer duration, it is important to study the effects of long-term human exposure to space in order to face them," Boada said in a statement.
"It's not unreasonable to start thinking about the possibility of reproduction beyond the Earth."
