Testosterone: a vascular hormone in health and disease - 0 views

  •  
    testosterone therapy has tremendous cardiovascular benefit in men with low T.  The key here is physiologic replacement of Testosterone.  Testosterone is a vasodilator and anti-inflammatory agent in men with low T.  Testosterone therapy improves cardiac function in those with DHF and angina.  Testosterone is found to be a Ca++ channel blocker--anyone say hypertension treatment?

Redefining Metabolic Syndrome in Men (July 2012) Townsend Letter for Doctors & Patients - 0 views

  • Approximately 95% to 98% of testosterone is bound to a carrier protein at any given time, leaving just the remaining 2% to 5% as completely unbound and available for tissues to use
  • most serum laboratories offer a free testosterone level, which is a calculated value based on SHBG levels or determined with equilibrium dialysis
  • the hormone enters the salivary gland by passive diffusion
  • ...11 more annotations...
  • Testosterone has a known age-related decline, and total levels typically drop by approximately 1.6% per year beginning for most men in their 30s
  • As estrogen levels rise, they prompt the body to produce more SHBG, which in turn has a higher binding affinity for testosterone, and drives the unbound fraction of the testosterone pool down even further
  • When the increase in SHBG is taken into account, the age-related decline in the level of hormone that can be used by the body is closer to 2% to 3% per year.
  • Stinging nettle (Urtica dioica), an herb commonly used for allergies, can also be employed to bind to SHBG, which leaves more testosterone available to tissues
  • Testosterone reduces lipoprotein lipase (LPL) activity
  • tumor necrosis factor alpha (TNF-alpha) and interleukin-1 (IL-1) further inhibit Leydig cell testosterone production
  • Natural aromatase inhibitors include the bioflavonoids chrysin and luteolin
  • Zinc deficiency causes an upregulation of the aromatase enzyme
  • Leptin, an adipose-derived peptide hormone that regulates appetite and metabolism, has been shown to directly inhibit testosterone production in animal models
  • there are several herbs that can work to boost testosterone levels, including longjack (Eurycoma longifolia), horny goat weed (Epimedium grandiflorum), and tribulus (Tribulus terrestris).
  • the majority of the hormone is bound to carrier proteins including sex hormone binding globulin (SHBG) and albumin

    nice and short review on testosterone and men's  health.

Analysis of Relations between serum levels of Epitestosterone, Estradiol, Testosterone,... - 0 views

  •  
    Great confusion exists in the medical profession about Testosterone and PSA and the health of the prostate. The conversion of Estrogen, whether E2 or E1, and other variables are responsible for increases in PSA while on Testosterone therapy. This study points out that Estradiol in men stimulates cell line growth of prostate cancer. In contrast, Epitestosterone, an androgen metabolite, has antiandrogen, inhibits this estrogen activity. Epitestosterone exists in an inverse relationship to Estradiol and IGF-1.

Prevalence and Correlates of Late-Onset Hypogonadism Among Korean Men Aged 40 Years or ... - 0 views

  •  
    Study of Korean men finds late onset of hypogonadism to be 16.8% in their study of 1,235 men older than 40.  This is a higher rate than other studies, but lower than others (38.7% in American men).  The test definition of low T was set at 3.2 ng/ml.  Abdominal obesity, metabolic syndrome, diabetes, and increasing age were associated with low T. Low T is clearly not a problem unique to America.  It definitely appears that a decreasing Testosterone level is a marker of poor health in men.

High Estrogen in Men After Injectable Testo... [Am J Mens Health. 2014] - PubMed - NCBI - 0 views

  •  
    Again, Testosterone and here Estradiol are merely there for libido and sex.  What tunnel vision?!  What about hsCRP?  What about fibrinogen?  What about IL-1beta?  What about TNF-alpha?  These inflammatory cytokines have all been reported to elevate as a result of estrogen production in men.   And PSA?  No mention of it here.   This linear, tunnel vision thinking on hormones has got to stop! The study points out that all clients were using AIs and SERMs irregardless of whether they had elevated estrogens or not.  That is not a well designed study.  One group should have had AI's if elevated estrogens were present and another group should not--this would compare the effects of aromatase activity.  Second, this was simply a retrospective chart review.  Third, a 50% conversion of 34,000 + men is very high when you look at the literature.  Fourth, they point to gynecomastia as a means of negative?  The cardiovascular implications are more significant.  These studies just seem to focus on superficial things.  Fifth, did libido problems exist before?  What were the free levels?   This falls in the paucity of data (2 studies) that point to excessive lowering of estradiol effecting libido and sexual performance.

Testosterone Levels Increase 50% with Weight Loss, Exercise - 0 views

  •  
    Weight loss increases Testosterone levels.  This author points to low Testosterone as merely a biomarker of poor health.  In some this is correct, but Testosterone can have significant positive effects.

  •  
    Australian study of older men, 70-89, found that normal Testosterone and DHT levels were associated with lower death rates.  This is important as this is the first study to find the positive health benefit of DHT as well as Testosterone.

Semen quality, infertility and mortality in the USA - 0 views

  •  
    Men with infertility associated with 2.3 fold higher risk of death. The factors evaluated were semen volume, sperm concentration, sperm motility, total sperm count, total motile sperm count.  Those that have 2 or more positive parameters were associated with increased death compared to those with normal semen analysis.

Gonadal dysfunction in systemic diseases - 0 views

  •  
    Systemic illness i.e. inflammation is associated with impaired HPA function and gonadal function.  This can be translated as low T.  Low Testosterone is a biomarker of poor health in men.

Total and free testosterone concentrat... [Clin Endocrinol (Oxf). 2012] - PubMed - NCBI - 0 views

  •  
    Testosterone levels appear to be more of a biomarker of poor health in older men that are obese with diabetes.  More of these men had low free Testosterone (calc) versus Total Testosterone.  Using QOL questionnaires, weak correlation (not statistically significant) with androgen deficiency symptoms and ED were found.

Lower sex hormone-binding globulin is more strongly associated with metabolic syndrome ... - 0 views

  •  
    low SHBG found to be more associated with metabolic syndrome in older men than low Testosterone.  The study consisted of 2502 men older than 70.  The authors proposed this occurs through the relationship between SHBG and insulin sensitivity.  I think that is a little too simplistic.

Testosterone suppression in opioid users: A systematic review and m... - PubMed - NCBI - 0 views

  •  
    Opioid use, despite type (including methadone), is associated with lower Testosterone in men.  This is not new information, but this meta-analysis reconfirms this relationship, particularly that methadone has the same effect.  This relationship was not found in women.  These physicians that regularly prescribe opiates  to men are doing them an incredible disservice.  A lower T in men is a significant negative health biomarker.

Selenium and human health : The Lancet - 0 views

  • Low selenium status has been associated with increased risk of mortality, poor immune function, and cognitive decline
  • Higher selenium status or selenium supplementation has antiviral effects, is essential for successful male and female reproduction, and reduces the risk of autoimmune thyroid disease.
  • Prospective studies have generally shown some benefit of higher selenium status on the risk of prostate, lung, colorectal, and bladder cancers, but findings from trials have been mixed, which probably emphasises the fact that supplementation will confer benefit only if intake of a nutrient is inadequate
  •  
    Selenium is a "U" shaped curve.  Abstract only available here.

  •  
    The harmful effects of chicken papilloma disease not only stop at physical health but also the spirit of patients is seriously affected. Patients may be depressed, mentally in crisis when they know that they can follow them all their lives. Chicken ridge is considered the undeniable obsession of men. Referring to this disease, many boys are bored, because once they get sick, the chicken's neck often hangs and leaves many harms. Dr. Vo Duy Tam said, "The chicken's crest is a sexually transmitted disease caused by HPV (Human Papilloma Virus) - The virus causes human papilloma. Currently there are more than 130 HPV types that have been discovered, among them, the ones that often cause genital warts are types 6, 11, 16, and 18.
