Coadministration of anastrozole sustains therapeut... [J Sex Med. 2014] - PubMed - NCBI - 0 views

  •  
    First, Testosterone pellets are not the way to go.  Historically, these will go the way of all the implantable contraceptive devices.  However, the conclusion of this study is good and confirms the benefit of anastrazole to inhibit aromatase activity and help to maintain Testosterone levels.

Reduced breast cancer incidence in women treated with subcutaneous testosterone, or tes... - 0 views

  •  
    Study finds that Testosterone with or with the aromatase inhibitor anastrazole as a pellet reduced breast cancer risk.  This conclusion should be taken with caution.  It is well know that abnormal breast tissue, breast cancer, highly expresses aromatase activity which would increase Testosterone to estradiol production.  This would feed any growing tumor.  But, this study finds protection.  The failure of this study is the measurement of hormone levels.

Endogenous Steroid Hormone Concentrations and Risk of Breast Cancer Among Premenopausal... - 0 views

  •  
    Prospective study finds that elevated total and free Estradiol levels in the follicular phase and elevated total and free Testosterone levels in both the follicular and luteal phase are associated with increased breast cancer in women.  The risk is for pre menopause in this study.  This and several other studies point to serious questions about the massive dosing of Testosterone via pellets, injections, and topicals for libido.  We appear to be following the same patter as seen with premarin, provera, now Testosterone in men and this may be the next ball to drop.  Is the Testosterone therapy merely producing an environment that feeds breast cancer?

Risk of Myocardial Infarction in Older Men Receiving Testosterone Therapy - 0 views

  •  
    This study appears to fly in the face of the recent studies on the dangers of Testosterone therapy in those with comorbidities.  This study was a retrospective cohort.  The study found that men in the highest risk for MI, had a reduced MI risk with Testosterone therapy.  Men in the lower risk quartiles had no such benefit.  Of note, the frequency of injections suggests inadequate dosing i.e. 4.4 in first year and 8.2 in follow up.  Most injection regimens will require at least monthly injections, though Testosterone pellets were used.  Of special note, no mention of level testing of Testosterone prior to study and/or during study and follow up.

Chest Binder - 0 views

  •  
    Tynor Chest Binder Chest Binder is applied to the thoracic region to compress and bind the rib cage and provide splinting to the sternum while allowing sufficient flexibility for comfortable breathing. Anatomic chest pad. Controlled compression. Optimum chest splinting. Soft feel. Tynor Chest Binder Features 50 mm thick PUF pad hold and binds the fractured sternum without compromising on patient comfort. Strong elastic band gives good grip and helps in equidistribution of pressure. Reduces post operative pain and discomfiture. Facilitates phlegm expulsion after cardio thoracic surgery. Tynor Chest Binder Measurements Measure circumference around the chest.

    Testosterone is great when needed, not doped; but Testosterone is not without risks.  Population case-control study finds increased blood clot risk in first 6 months of Testosterone therapy.  To many variables left unanswered by this study.

Transdermal testosterone replacement therapy in men - 0 views

  • a recent study has suggested that it may sometimes be inaccurate because of abnormal fluctuation of other circulating androgens

      The authors are referencing the increase in the suggestions to use other testing techniques i.e. saliva.
  • Testosterone therapy can inhibit hepcidin transcription and is associated with increased iron incorporation into red blood cells and increased erythropoietin concentrations
  • Transdermal TRT has a more favorable adverse effect profile when compared to buccal testosterone formulations
  • ...13 more annotations...
  • Approximately 0.3% of testosterone is converted into estradiol by aromatase (CYP19A1)
  • the recommendation for injectable testosterone esters is to check the serum concentration midway between injections
  • it is recommended for serum testosterone to be evaluated 3 to 12 hours after application of the transdermal patch
  • testosterone concentrations should be checked 2–3 months after initiation of therapy and after adjusting the dose
  • a study from 1989 utilizing testosterone transdermally containing 5, 10, or 15 mg of testosterone showed that peak concentrations of testosterone were achieved 3 to 8 hours after scrotal application in hypogonadal men
  • It is used for many medications and has the advantage of high bioavailability, absence of hepatic first pass metabolism, increased therapeutic efficacy, and steadiness of plasma concentrations of the drug
  • evaluate serum testosterone at the end of the dosing interval for testosterone pellets
  • increased amount of fat leads to increased extragonadal aromatase activity, resulting in increased concentrations of estradiol. High circulating concentrations of estradiol down regulate the HPG axis and decrease the amount of circulating testosterone
  • Up to 80% of plasma estradiol originates from aromatization of testosterone and less than 20% of estradiol in the circulation is secreted by the testes
  • A PSA concentration, digital rectal examination, and hematocrit should be performed at baseline and at 3 months, 6 months, then yearly after TRT is initiated.
  • measure serum testosterone any time after the patient has been on treatment with gel for at least 1 week
  • If the hematocrit rises above 54%, treatment should be discontinued
  • elderly men having higher estradiol serum concentrations than postmenopausal women
