Testosterone is the primary male sex hormone and androgen in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Lipase is a digestive enzyme that breaks down fats in food so the body can absorb them in the intestines. It's produced in the pancreas, mouth, and stomach, and is found in many tissues.
