Space tourists will be banned from having sex during the flight.

Scientists warn about the dangerous effects of radiation on the embryo if a child is conceived. While astronauts are taught to restrain any sexual urges during extended periods in space, less prepared tourists may not be as reticent. Because conceiving a human in space poses a risk to both the unborn child and the burgeoning space tourism sector, tourists will be required to sign a waiver of in-flight sex.
