Explanation: 

Detailed explanation-1: -The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat. By age 75, the thymus is little more than fatty tissue. Fortunately, the thymus produces all of your T cells by the time you reach puberty.

Detailed explanation-2: -Thymic hyperplasia alludes to an increase in the size of thymus due to an increase in the number of cells. Thymus achieves its peak size around puberty and then atrophies slowly.

Detailed explanation-3: -Thymic hyperplasia is an increase in size and weight of a thymus gland that is otherwise normal. It usually is a rebound phenomenon after atrophy caused by corticosteroids or chemotherapy, and it occurs several months after resolution of the cause of atrophy. Occasionally, it may result from hyperthyroidism.
