• Testosterone

    What is testosterone?

    testosteroneTestosterone is the principal androgen, or male sex hormone, although it it is also needed (in a much smaller amount) by a woman’s body. It is classified as an anabolic steroid because it will bulk up body tissues and encourage the retention of protein by the body. In both men and women, testosterone is produced in the gonads, and it is derived from cholesterol.

    What does testosterone do?

    Testosterone isn’t just a sex hormone, it is essential for sexual function, but has many other uses as well. Testosterone plays a pivotal role for men and women in maintaining lean body mass, skin elasticity, libido (sex drive) and healthy immune system. It ensures proper heart function, regulates mood and aids brain function (cognition), controls blood sugars, regulates healthy cholesterol, controls blood pressure, prevents heart attacks and even reduces risk of prostate cancer. Testosterone is a hormone that influences our personality; it gives us a sense of well-being and empowers us to take actions in life. Testosterone increases feelings of emotional comfort, self confidence and assertiveness. When testosterone levels are in balance we are able to live our lives with passion!

    Testosterone production in women:

    Along with the two other vital hormones, progesterone and estrogen, testosterone production declines as a woman ages. In women, testosterone is produced by the ovaries and the adrenal glands. Testosterone has both a physiological and a psychological impact on women sexuality, it enhances libido in women. Testosterone increases muscle mass and strength and decreases body fat. Testosterone helps you feel more energetic. If a woman is thrown into surgical menopause (by having her ovaries removed), she abruptly loses 50% of her natural testosterone and 80% of her natural estrogens. Women, like men, need adequate testosterone for peak mental acuity, healthy bone density and muscle tissue.

    It is important to note, estrogen replacement therapy without balancing testosterone at the same time can lead to even greater testosterone deficiency in postmenopausal women.

    Declining estradiol and progesterone levels after entering menopause are compounded by falling testosterone and thyroid hormone. This declining hormonal environment fuels bodily changes such as: a flux in metabolism, altered libido, effects on breasts, vagina, bones, blood vessels, gastrointestinal tract, cardiovascular system, skin, mental acuity.

    Testosterone also helps to prevent unwanted fat, heart disease and cognitive decline in women. Without it, women would have a 50% chance of experiencing pathological hip or vertebra fracture. Especially frightening is that 20% of hip fracture patients die within a year of their surgery.

    Testosterone aids in bone growth, improves protein synthesis and anabolic functions. The fact that men produce more testosterone than woman is evidenced by the increased bone and muscle mass.

    Symptoms of low testosterone levels in women

    • low libido (sex drive)
    • Depression
    • Hot flashes
    • Loss of muscle mass
    • Brittle bones
    • Osteoporosis

    Testosterone production in men:

    In men, testosterone production is initiated by the pituitary gland, deep within the brain. The pituitary gland secretes luteinizing hormone (LH), which stimulates Leydig cells in the testicles to produce testosterone. In men, testosterone hormone deepens the voice during puberty, stimulates the growth of facial and body hair, increases sexual drive, and is responsible for sperm production. Furthermore, testosterone contributes to liver function, muscle mass and strength, the ability to produce erections and sexual stamina. While women also produce testosterone, it is in much smaller levels. Testosterone is the main male hormone that differentiates men from women.

    Stimulating hormones, such as testosterone, become less effective as we age, making supplementation imperative. Having low testosterone levels results in andropause (male menopause).

    Symptoms of low testosterone levels (andropause) in men

    • Loss of body and facial hair
    • Loss of muscle mass
    • Hot flashes
    • Brittle bones
    • Depression
    • Increased breast size

    Testosterone hormone replacement therapy can return the male body to normal testosterone levels. The appropriate testosterone replacement therapy is to stimulate the LH, causing the testicle to produce more testosterone on their own.
