What happened? Action man has become inaction man. Sex hormone binding globulin (SHBG) is the key player in the who stole the testosterone mystery. It grabs the hormone and runs, and won’t let go. The more SHBG, the less free, active, “bioavailable” testosterone can get out into the blood and then to the cells to do its job.
Its called Andropause, yes the male version of Menopause in women. It’s about aging. “If I had known I was gonna live this long, I would have taken better care of myself.” This quote from Jimmy Durante sums it up. Men take better care of yourselves, please.
Andropause profile: Low Testosterone/High Estrogen. Estrogen is not just in female bodies, men need it too, in smaller amounts to regulate brain function and stimulate sexual function. In andropause, estrogen can overtake waning testosterone to complicate symptoms and raise the risk of prostate cancer. Remembers those SHBG’s I mentioned? Well, when they bind up the testosterone it activates an enzyme in fat cells that changes testosterone into more estrogen!
What can you do, you ask? Work with your health care professional to monitor hormone levels. Supplement with the highest natural bioavailable vitamin/mineral, antioxidant nutrition program. Reduce Testosterone Robbers: caffeine, alcohol, and sugars. Go organic eat hormone free meats if you are a meat eater. Hit the sack earlier.
Okay guys, that’s a start, there is much more. Until next time.
Wanting the best of health, wealth and happiness for you always.
In Harmony, Love and Light

What is SHBG good for? Why are they exist in our system?
Sex hormone-binding globulin (SHBG) is a glycoprotein that binds to sex hormones, specifically testosterone and estradiol. Other steroid hormones such as progesterone, cortisol, and other corticosteroids are bound by transcortin.
Transport of sex hormones
Testosterone and estradiol circulate in the bloodstream, bound mostly to SHBG and to some degree bound to serum albumin. Only a small fraction is unbound, or “free,” and thus biologically active and able to enter a cell and activate its receptor. The SHBG inhibits the function of these hormones. Thus bioavailability of sex hormones is influenced by the level of SHBG.
[edit]SHBG production
SHBG is produced by the liver cells and is released into the bloodstream. Other sites that produce SHBG are the brain, uterus, and placenta and vagina. In addition SHBG is produced by the testes; testes-produced SHBG is also called androgen-binding protein. The gene for SHBG is located on chromosome 17.
