Sex in Space? Beware the Radiation, Scientists Say.
Astronauts sent to colonize Mars would be well advised to avoid getting pregnant en route to the Red Planet, according to a review of radiation hazards by three scientists.
High-energy particles bombarding the ship would almost certainly sterilize any female fetus conceived in deep space, making it that much more difficult to establish a successful Mars colony once the crew lands.
"The present shielding capabilities would probably preclude having a pregnancy transited to Mars," said radiation biophysicist Tore Straume of NASA Ames Research Center, lead author of the review published in the Journal of Cosmology.
