Which gland works from infancy to puberty then disappears?

The gland that functions from infancy to puberty and then gradually disappears is the thymus gland. It plays a crucial role in the development of the immune system by producing T-lymphocytes, which are essential for adaptive immunity. As a person reaches puberty, the thymus shrinks and is replaced by fatty tissue, a process known as thymic involution. This reduction in size is part of the body’s natural development as the immune system matures.
