no not necessarily. actually it is mumps not measles that has a predilection for causing problems in the gonads. complications of measles tend to be more central nervous system / neurological. namely things like meningitis. i guess it would be possible for a severe case of measles to cause issues with the reproductive tract but this would not likely be a common complication. worldwide measles remains among the leading causes of childhood deaths. this is why vaccination is so so important.
do boys with measles become sterile?
