Hypothalamus - Wikipedia

A hormone is a chemical substance of an endocrine gland. Endocrine glands, which are also called ductless glans, deposites the hormones into the blood stream. The blood, on its turn, carries the hormones to every part of the body. The sex hormones are estrogen and testosterone. Like all hormones, they are chemical messengers, substances produced in one part of the body that go on to tell other parts what to do. Both women and men produce both estrogen and testosterone, though in different quantities, and both sexes produce less as they age. These hormones seems to affect arousability by altering the threshold for erotic stimulation.

Hypothalamus

The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus. When the hypothalamus is not working properly, it can cause problems in the body that lead to a wide range of rare disorders. Maintaining hypothalamic health is vital because of this. Homeostasis means a healthful, balanced bodily state.
