  • The benefits of restoring serum testosterone in men with LOH were not significantly different between men older than 65 years of age and younger men. There were no indications that side effects were more severe in elderly men. The effects on prostate and urinary function and hematocrit were within safe margins.
  • obesity, but also impaired general health, are the more common causes of low testosterone in aging men
  • Severe LOH is associated with substantially higher risks of all-cause and cardiovascular mortality,
  • ...30 more annotations...
  • advanced age, obesity, a diagnosis of metabolic syndrome, and poor general health status were predictors of LOH
  • Diabetes mellitus was correlated with hypogonadism in most studies
  • coronary heart disease, hypertension, stroke, and peripheral arterial disease did not predict hypogonadism, they did correlate with the incidence of low testosterone
  • LOH can be defined by the presence of at least three sexual symptoms associated with a total testosterone level of less than 11 nmol/L (3.2 ng/mL) and a free testosterone level of less than 220 pmol/L (64 pg/mL)

      the European Male Aging study defined low T as total < 320 ng/dl and free < 64 pg/ml.  
  • Mean weight decreased
  • Waist circumference decreased
  • Total cholesterol decreased
  • Low-density lipoprotein decreased
  • Triglycerides decreased
  • High-density lipoprotein (HDL) increased
  • ratio of total cholesterol to HDL improved
  • Prostate volume increased
  • PSA increased
  • The benefits for men older than 65 years of age were compared with those of younger men, and the improvements in body weight, metabolic factors, psychological functioning, and sexual functioning were of the same magnitude in both age groups
  • weight loss was progressive over the 6-year period, effects of testosterone on lipids and on psychological and sexual functioning reached a plateau after approximately 3 years and these effects were sustained
  • Effects of testosterone on hematopoiesis, on the prostate, and on bladder function were not more severe in older men than in younger men
  • observe a mild increase in prostate volume and serum PSA over time, which is a normal finding in aging men. Maybe somewhat surprising, postvoiding residue and the IPSS did not deteriorate with aging but showed a degree of improvement
  • the severity of the metabolic syndrome is associated with the severity of lower urinary tract symptoms
  • The symptoms of the metabolic syndrome improve upon testosterone treatment and testosterone may thus have a favorable effect on lower urinary tract symptoms
  • it seems reasonable to conclude that the risks of testosterone administration to elderly men are not disproportionately higher in elderly men than in younger men.
  • Despite evidence to the contrary, physicians still harbor a wrongful association between testosterone and the development of prostate pathology (prostate cancer and benign prostate hyperplasia)
  • Not surprisingly, the incidence of prostate cancer was higher in older men; however, it was lower than expected in both groups
  • These observations suggest that the incidence of prostate cancer in patients receiving testosterone therapy, both in the younger and in the older group, was not greater than in the general population not receiving testosterone treatment
  • The historical fear that raising testosterone levels will result in more prostate cancer has been dispelled, particularly by the work of Abraham Morgentaler
  • Higher serum testosterone levels fail to show an increased risk of prostate cancer, and supraphysiological testosterone does not increase prostate volume or PSA in healthy men
  • This apparent paradox is explained by the "saturation model,"
  • Recent studies indicate no increased risk of prostate cancer among men with serum testosterone in the therapeutic range
  • In the present observational study, no cases of major adverse cardiovascular events occurred.
  • the benefits of testosterone therapy are fully achieved only by long-term treatment
  • To achieve maximal benefits, good patient adherence is a prerequisite

  • overall mortality and CV mortality were inversely associated with serum T concentrations.
  • men with low serum T, defined as &lt; 8.7 nmol l−1 (250 ng dl−1 ), demonstrated significantly greater all-cause mortality than men with higher serum T (hazard ratio [HR]: 2.24; 95% CI: 1.41-3.57), as well as greater CV mortality
  • lower T levels were significantly associated with the presence of any CV disease
  • ...19 more annotations...
  • more than 30 years of studies suggesting that low levels of T represent an increased risk for CV and overall mortality,
  • lower serum T concentrations also are associated with CV disease, including incident coronary artery disease [17],[18],[19] and atherosclerosis,
  • the actual rate of adverse events was only half as great in the T group (123 events in 1223 men at risk = 10.1%) as in the untreated group (1587 events in 7486 men = 21.2%)

  • 29 medical societies have called for retraction of the article, asserting "gross data mismanagement and contamination," that rendered the study "no longer credible
  • Mortality in T-treated men was reduced by approximately half in treated men compared with untreated men, at 10.3% versus 20.7%, respectively
  • The mortality rate for men who received TTh was 3.4 deaths per 100 person-years, and 5.7 deaths per 100 person-years in untreated men

    Great review by Morgentaler of Testosterone and CVD.  He highlights the significant flaws in the JAMA and the NEJM articles of Testosterone therapy risks.  Morgentaler highlights the significant evidence that points to low T and increased risk of CVD. On contention I have, is Morgantaler seems to flip aside the massive uptick of Testosterone use in the US as compared to other countries.  The evidence definitely points to Testosterone therapy as being safe in those with low T, but there is definitely a problem of significant Testosterone doping that is taking place as well.

  • 0.4–2% annual decline
  • the age trend in free T was more substantial (−1.3% per annum)
  • The core hormonal pattern with increasing age is suggestive of incipient primary testicular dysfunction with maintained total T and progressively blunted free T associated with higher LH.
  • ...16 more annotations...
  • Obesity was associated with progressively lower total and free T independent of the simultaneous decrease in SHBG.
  • our data highlight the fact that LH was unchanged or even lower in older men in the face of lower T in obesity, suggesting that there may be a failure at the hypothalamic-pituitary level.
  • a change in BMI from nonobese to obese may be equivalent to a 15 yr fall in T.
  • This pattern supports the hypothesis that different underlying mechanisms influence the functions of the HPT axis: age predominantly affects testicular function, whereas obesity impairs hypothalamic/pituitary function.
  • the effects of aging on testicular function can be moderated by increased LH compensation for many decades
  • obesity impairs hypothalamic/pituitary function independent of age, arguably an adaptive response for which there should be no compensatory mechanism.
  • the concurrent but opposite (and separate) effects of obesity and age on SHBG
  • SHBG was negatively associated with increasing strata of obesity
  • Obesity is associated with insulin resistance (28), and the increased circulating insulin inhibits hepatic SHBG synthesis
  • the SHBG increase with age may be related to relative IGF-I deficiency (27), although this has not been directly proven.
  • Obesity is associated with peripheral and central insulin resistance (30) and proinflammatory cytokine production (TNFα and IL-6) from adipocytes (31) and central nervous system endocannibinoid release (32), all of which are potential candidates for abrogating hypothalamic endocrine and downstream reproductive axis functions.

      The HPA axis effect may be the result of inflammation.
  • The relationship between obesity and T can be bidirectional: low T may be the cause rather than consequence of obesity
  • chronic alcohol abuse is known to suppress LH (40), our data showed no significant association among the three hormones or SHBG and alcohol intake.
  • increase in total T in smokers occurs through a primary increase in SHBG with a compensatory rise in LH
  • the effects of obesity (BMI or waist circumference) was by far the most important determinant of variance in total T, whereas age per se was important for SHBG, LH, and free T with comorbidity and smoking being comparatively minor contributors
  • It is noteworthy that these predisposing lifestyle and health factors are modifiable. This implies that the apparent age-related decline in T may constitute a barometer of health and thus be potentially preventable and/or reversible.
  • Nathan Goodyear on 03 Sep 14
     
    Age induced decline in Testosterone is more associated with a decline in leydig cell function and thus elevated LH will be associated.  In contrast, obesity is more of a HPA axis disruption and thus LH may be normal to low.  The pulse amplitude is decrease.  No change in pulse frequency is noted.   With obesity, a decline in TT and fT was independent of SHBG. Aging is associated with a greater decrease in fT versus TT.

  • The prevalence of hypogonadism (often defined as serum testosterone &lt; 300 ng dl−1 ) ranges from 6% [10] to as high as 38%
  • The process of BPH, however, continues as men age and despite the fact their serum testosterone decreases
  • Liu et al. [12] demonstrated that in a group of older males (mean age 59.8 years) that there was not a significant correlation of serum testosterone levels (total, free or bioavailable) with either prostate volume or International Prostate Symptom Score (IPSS)

  • in eugonadal men, studies have demonstrated that the prostate can increase in volume by approximately 12%
  • There seems to be little doubt that the treatment with testosterone of a young hypogonadal male leads to significant growth of the prostate
  • Behre et al. [22] demonstrated increased prostate volume and prostate-specific antigen (PSA) levels in hypogonadal men
  • Most studies, however, have shown no effect of exogenous androgens on PSA or prostate volume for older hypogonadal males
  • saturation model
  • They argue that the prostate is relatively insensitive to changes in androgen concentration at normal levels or in mild hypogonadism because the AR is saturated by androgens and therefore maximal androgen-AR binding is achieved. Conversely, the prostate is very sensitive to changes in androgen levels when testosterone is low
  • visceral obesity (one of the most significant components of metabolic syndrome) is associated with prostate volume and influences prostate growth during TRT.
  • This hypothesis of inflammation induced LUTS is also argued to be a mechanism for improvement of LUTS with PDE5I
  • The concept, therefore, that treatment with TRT of hypogonadal males with metabolic syndrome might lead to improvement/stabilization of their LUTS, appears to be confirmed in recent work by Francomano et al.
  • There was also an improvement in components of the patient's metabolic syndrome (such as BMI, waist circumference, hemoglobin A1c [HbA1c], insulin sensitivity, and lipid profile) as well as inflammatory markers and C-reactive protein.
  • They concluded that TRT was safe in this group of men, and hypothesize that TRT mitigates the pro-inflammatory factors associated with metabolic syndrome.

  • higher plasma vitamin C status is associated with lower circulating levels of blood triglycerides, insulin and HbA1c
  • A role for vitamin C in the prevention or management of diabetes and/or metabolic syndrome has been suggested
  • In this study, we also demonstrate lower levels of mild cognitive impairment in those with high vitamin C status
  • The odds of mild cognitive impairment were twice as high for those below 23 μmol/L plasma vitamin C concentration.
  • Vitamin C is present at very high concentrations in the brain
  • animal models have shown that the brain is the last organ to be depleted of the vitamin during prolonged deficiency
  • A recent animal study has shown that moderate vitamin C deficiency may play a role in accelerating amyloid plaque accumulation in Alzheimer’s disease
  • Nathan Goodyear on 28 Feb 18
     
    New study: vitamin C levels correlate with cognitive and metabolic health. What is your vitamin C level? Despite the adequate levels of vitamin C intake, a large % of the individuals had inadequate vitamin C levels which points to a demand issue.  Higher oxidative stress, chronic inflammation... would drive demand for vitamin C higher. Lower vitamin C levels were associated with more metabolic disease, ie. DM, and more cognitive decline.
