A new study has found that exposure to cosmic rays on space missions could cause erectile dysfunction in astronauts. The study, which was conducted on rats, found that exposure to cosmic rays impaired blood flow to the erectile tissue in the penis. The researchers say that the effect could be reduced using antioxidant drugs. The study also found that weightlessness could have a similar effect, but not as pronounced. The findings could have implications for future space missions, as astronauts may need to take steps to protect themselves from cosmic-ray exposure. By Coshorts
