Dr Levin has found that little is known about sexual physiology in space, and how people’s bodies work in these unusual conditions. “There’s the effect of the absence of gravity; the effect of radiation; and the effect of being caught up in the very small environment with a lot of other people. All these things are going to have effects on human sexuality and reproduction. At the moment the attitude is: don’t have sex in space because we can’t cope with it. But sooner or later it’s going to be a much greater problem, when we have long voyages – say three years to Mars.
