Another effect of radiation exposure is sterility. Radiation exposure may lead to a reduction of cell division in the testes of the male or a loss of fertile eggs in the ovaries of the female.

An acute dose of to the gonads of the adult male induces a temporary sterility (but not impotence) that may last a few months. An acute gonad dose of to either sex would induce permanent sterility . Of course, this is a consideration only for a local exposure because a whole-body dose of this magnitude would be lethal.

Answer 3

Radiation can have a terrible effect on a man's ability to have children. How severe the effect will be depends on:
1. the type of radiation he will be exposed to
2. what type of protective gear he wears (PPE)
3. how long the actual exposure lasts.
