Temperature can affect a couple of different variables in a ball to alter the distance it will travel from an impact. For inflated balls, the temperature can change the air pressure inside the ball giving an over inflated effect if it was warmed, or and under inflated effect if it was cold. (Have you ever tried dribbling a basketball without enough air in it?) The amount of air pressure then is directly proportional to the temperature of the air inside.

Yes , the balls drop to reduce the testis temperature. If they remain in body, the sperm may die due to the higher temperature.
If there is a mass other then your balls you do need an operation.
It the ball has air in it, then an increase of temperature will increase the pressure within the ball, over the short term. Over the long term, all pressurized tennis balls lose pressure. If the ball is the pressureless type, it has no air to be affected by temperature.

There are a number of names for the balls - generally they are called zorbing balls or OGOs.
