    <B>Hormone Function -- a Brief Description</B>

    Cortisol – (stress hormone)

    Increases during stress, also with aging.
    Reduced inflammatory response; impairs immune function
    Associated with diabetes, osteoporosis, memory loss and Alzheimer’s.

    DHEA

    Energizes
    Enhances libido
    Restores memory
    Rejuvenates the immune system
    Tames stress
    Fights cancer
    Prevents heart disease
    Reduces body &amp; fat
    Therapy for menopause
    Helps erase fine wrinkles
    Helps dry eye
    New hope for lupus suffers
    Heals burns
    Increases testosterone levels

    Estrogen

    Relieves menopausal symptoms
    Protects against heart disease
    Restores sexual function
    Sharpens thinking
    Enhances mood
    May prevent Alzheimer’s disease
    Prevents osteoporosis
    Reduces risk of colon cancer
    Prevents tooth loss
    Improves skin quality

    Glucagon

    Reverses the action of insulin

    The Gonadotropins

    FSH (Follicle Stimulating Hormone) is a gonadotropin produced by the pituitary and is released under the control of the hypothalamus. FSH is also required for the testicular growth and spermatogenesis. In the female, FSH stimulates follicular (ovum/egg) growth of the ovary and prepares ovarian follicles for action by luteinizing hormone (LH), and enhances the LH-induced ovarian release of estrogen. After menopause, decreased ovarian estradiol secretion results in increased FSH and LH levels. Primary testicular failure also results in increased FSH and LH levels.
    In the male, FSH secretion is regulated by inhibin, a peptide hormone produced by Sertoli cells from the testes, and also by circulating testosterone feedback inhibition on the pituitary and the hypothalamus.

    LH (luteinizing hormone) is another gonadotropin produced by the pituitary, and is also released under the control of the hypothalamus. Production is regulated by hypothalamic gonadotropin releasing hormone (GnRH) and feedback by gonadal steroid hormones, as is FSH. In the female, LH stimulates ovarian steroid hormone production (estrogen and progesterone).
    LH concentrations are low during the follicular phase of the menstrual cycle, rise to a midcycle peak to cause ovulation, and following ovulation, fall to levels lower than during the follicular phase. After menopause, LH concentrations rise to levels as high or higher than those found in the midcycle peak; similar high levels are seen in castrated men.

    In the male, LH stimulates androgen production by the testicular Leydig cells. The testes require the androgen, testosterone, to maintain the process of spermatogenesis, and the accessory organs are dependent on androgen for proper secretory function. The production of LH is regulated by feedback inhibition of circulating testosterone on the pituitary and hypothalamus.

    Human Growth Hormone

    Builds muscle
    Enhances immune function
    Strengthens the heart
    Helps control stress-induced damage
    Aids kidney function
    Enhances orgasmic intensity
    Lowers blood pressure
    Lowers cholesterol
    Long-term use reduces insulin requirements in diabetics
    Stimulates nerve cell growth and repair in brain, spinal cord, &amp; peripheral nerves
    Stimulates joint repair from damaged cartilage, tendons
    Decreases body fat (particularly abdominal organs)
    Increases extracellular fluid
    Speeds healing from burns, surgery, fractures
    Restores bone loss of osteoporosis
    Reverses congestive heart failure
    Restores youthful drive &amp; energy
    Restores pulmonary function in chronic lung disease
    Improves mood &amp; sleep patterns
    Thickens skin, restores tone &amp; elasticity
    Promotes hair &amp; nail growth
    Reduces susceptibility to illness
    Protects against early cancer cell formation
    Stimulates growth &amp; repair of all organs of the body

    Amylin -- Insulin’s Partner Hormone

    A pancreatic beta-cell hormone that is co-located and co-secreted with insulin.
    In people without diabetes, amylin is believed to suppress glucagon secretion during the postprandial period through a central effect mediated by an efferent pathway of the vagus nerve.
    It also is believed to modulate nutrient delivery from the stomach to the small intestine through a similar pathway.
    The result is tight regulation of circulating glucose in the postprandial state.

    Resistin

    A hormone produced by adipose tissue (fat cells), has recently been described by Lazar and co-workers.
    Derives its name from its effects on insulin action. In some animal models, resistin has been shown to increase insulin resistance in peripheral target tissues, although the mechanism of action is not known.

    Adiponectin

    Produced by adipose tissue, is a beneficial hormone with regard to lipotoxicity.
    Enhances FFA uptake (free fatty acids) and oxidation, resulting in less triglyceride being stored in the muscle. It also reduces free fatty acid uptake and triglyceride storage in the liver.
    Reduces circulating lipids and enhances insulin sensitivity and, therefore, is considered to be antiatherogenic. Not surprisingly, a recent study found that obese patients, with and without type 2 diabetes, had low serum levels of adiponectin.

    Leptin

    Also produced by adipose tissue, has direct effects on fat cells in addition to its effect on appetite.
    It increases glycerol release and FFA oxidation and reduces lipogenesis and triglyceride synthesis.

    Insulin

    Transports glucose into the cells

    Melatonin

    Extends life
