"Adolescent" refers to a young person who has started puberty but not yet reached adulthood, and is not a hormone. Hormones in general are produced by many different glands within the body, including the thyroid and renal glands.
Oil from the sebaceous glands is produced by the cells' endoplasmic reticulum and Golgi apparatus within the cytoplasm. These organelles are responsible for synthesizing and secreting the sebum, which helps lubricate the skin and hair.
The nipple feeds by providing mother's milk for the infants. The milk is produced within the glands of the breast and come through the tip of the nipple.

Salivary amylase is produced by the salivary glands, primarily the parotid glands, located near the jaw. When food enters the mouth, these glands are stimulated by the nervous system to secrete saliva, which contains the enzyme amylase. Salivary amylase begins the process of carbohydrate digestion by breaking down starches into simpler sugars. The enzyme is synthesized from specific proteins within the glandular cells and packaged into vesicles for secretion.
Sugar-rich liquid produced in glands called nectares is what flower nectar is. It may be found within the flower in order to attract pollinators. But nectar also may be produced in glands outside the flower in order to attract non-pollinators into defensive arrangements whereby the entire plant is protected against unwanted predation.
Examples of glands located within the digestive tube include the salivary glands, which secrete saliva in the mouth; gastric glands, found in the stomach and produce gastric juices; and the pancreas, which secretes digestive enzymes and bicarbonate into the small intestine.
Exocrine secretions are produced by specialized cells within exocrine glands, such as acinar cells in the pancreas and mucous cells in the salivary glands. These cells are responsible for synthesizing and releasing substances into ducts or the external environment.
The pearl is produced by the pearl oyster and is a natural response to sand and other irritants within the animal.
The parathyroid glands are on the thyroid.
The testes are the glands that produce both sperm and the male sex hormone testosterone. Sperm is produced in the seminiferous tubules, while testosterone is produced in the Leydig cells within the testes.
