    In obese men with low T and type 2 diabetes, Testosterone replacement improves insulin sensitivity.  Glycated hemoglobin was also improved.  In this study group, a decrease in visceral adiposity and TC was seen.

    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.

    Study of 2361 Chinese men found that men with MetS had lower TT, bioavailable Testosterone, free Testosterone and SHBG than those men without MetS.  Additionally, Total Testosterone and SHBG were both inversely associated with the risk of MetS.  This inverse association stood for both after adjusting for the other.

    Men with low T and low SHBG have a significantly elevated risk of metabolic syndrome.  Other studies have actually shown that low SHBG is more associated and that TT is more than free Testosterone.

cardiovascular risk disease lipoprotein a Lp(a) LDL lipoprotein(a) niacin

shared by Nathan Goodyear on 06 Aug 14 - No Cached
  • Lipoprotein(a) is a plasma lipoprotein consisting of a cholesterol-rich LDL particle with one molecule of apolipoprotein B100 and an additional protein, apolipoprotein(a)
  • Elevated Lp(a) levels can potentially increase the risk of CVD (i) via prothrombotic/anti-fibrinolytic effects as apolipoprotein(a) possesses structural homology with plasminogen and plasmin but has no fibrinolytic activity and (ii) via accelerated atherogenesis as a result of intimal deposition of Lp(a) cholesterol, or both
  • evidence suggests that apolipoprotein(a) adducts extracellularly and covalently to apolipoprotein B100-containing lipoproteins, predominantly LDL
  • ...2 more annotations...
  • Lp(a) is relatively refractory to both lifestyle and drug intervention.
  • Other agents reported to decrease Lp(a) to a minor degree (<10%) include aspirin, l-carnitine, ascorbic acid combined with l-lysine, calcium antagonists, angiotensin-converting enzyme inhibitors, androgens, oestrogen, and its replacements (e.g. tibolone), anti-estrogens (e.g. tamoxifen), and thyroxine replacement in hypothyroid subjects

    low SHBG in post-menopausal women correlates with increased risk of metabolic syndrome.  More than that, there is an inverse correlation with SHBG in women and metabolic syndrome components.  Also, Increasing components of MetS was correlated with Testosterone and free androgen index.

    Interesting study finds hyperandrogenism stimulates excessive inflammatory response to glucose intake.  This study was done in otherwise healthy women not in women with PCOS.  The inflammatory cytokine production was via NF-KappaB activation.  Again, this has negative implications in women being doped with Testosterone.

    Very insightful study.  Study looked at hyperadrogenism and inflammation in women on the orders of PCOS.  The study subjects did not have PCOS, but hyperandrogenism via 130 mg DHEA was associated with an increase in TNF-alpha in these lean o/w healthy women.  We know this is due to hyperandrogenism as elevated Testosterone, DHEA, and androstenedione were documented with treatment. Take home:  androgens promote inflammation in women.  I believe this has serious negative implications about the massive Testosterone doping that is occurring in women today.
