There are plenty of normal people who can ' t conceive for whatever reason , especially given the high radiation levels which would leave many prone to sterility . And my guess would be they do have a functional system , but certain genetic markers make them unable to create viable gametes . <| sep |> Most people won ' t go on record giving that information away . Your comment scares me , not to be insulting , because I think we are entering a new age where we no longer trust the media to report on things . Unless we have first hand source ourselves we are just going to reject information out right and that won ' t work either . There will always be a bias in reporting but we have to be careful to reject all information just because it can ' t satisfy our personal threshold . It is like we are losing trust in each other , not just the media .
