What Hormone Does the Thymus Gland Produce?

The thymus gland produces the hormone Thymosin, which stimulates the production of antibodies. The Thymus also creates T-lymphocytes, which are white blood cells used to combat infection and abnormal cells, and Thymopoietin, which is a protein present in mRNA.

The thymus gland is most active in children, reaching its peak at puberty and gradually shrinking and becoming less active. An essential part of the immune system, it is composed of two lobes and is located centrally in the upper chest, in front of the trachea. Cancer of the thymus gland is rare but not unheard of, with diagnosis by microscope analysis of tissue samples.
