A Closer Look At The Benefits of TRT (Case Studies)

Normalization of total testosterone levels after TRT was associated with a significant reduction in all-cause mortality, MI, and stroke


Objective: To examine the relationship between the normalization of total testosterone (TT) after TRT and CV events as well as all-cause mortality in patients without previous history of MI and stroke

  • 83,010 male veterans with documented low TT levels


Conclusions: Normalization of TT levels after TRT was associated with a significant reduction in all-cause mortality, MI, and stroke.

Long-term treatment with testosterone undecanoate injections in men with hypogonadism alleviates erectile dysfunction and reduces risk of major adverse cardiovascular events, prostate cancer, and mortality.


Objective: The association between erectile dysfunction (ED), hypogonadism, cardiovascular disease, and type 2 diabetes is well documented, but long-term data are limited. The aim of this study is to investigate effects of long-term testosterone therapy (TTh) with testosterone undecanoate in men with hypogonadism and ED.


  • 805 hypogonadal men with different degrees of ED 

  • 412 patients w/ testosterone therapy

  • 393 patients served as controls

  • Observation period up to 12 years

  • Patients must stay on testosterone therapy consistently for a long time to achieve maximum benefits


Conclusions: Long-term testosterone therapy alleviates ED, improves cardiometabolic risk factors, and reduces prostate cancer

Remission of type 2 diabetes following long‐term treatment with injectable testosterone undecanoate in patients with hypogonadism and type 2 diabetes: 11‐year data from a real‐world registry study


Objective: To investigate whether testosterone therapy in men with hypogonadism and type 2 diabetes mellitus improves glycemic control and insulin sensitivity, and results in remission of T2DM.

  • 365 men with symptoms of TD

  • Followed over 11 years

  • All were treated with standard diabetes treatment 

  • 178 received parenteral testosterone undecanoate 1000mg every 12 weeks 

  • Control group not treated with T

Results:

  • Patients treated with T had significant progressive and sustained reductions in fasting glucose, glycated hemoglobin (HbA1c), and fasting insulin

  • Control group fasting glucose, HbA1c, and fasting insulin increased.

  • Patients treated with T

  • 34.3% achieved remission of their diabetes

  • 46.6% of patients achieved normal glucose regulation

  • 83.1% reached the HbA1c target of 47.5 mmol/mol (6.5%) and 

  • 90% achieved the HbA1c target of 53.0 mmol/mol (7%).

  • Control group

  • No remission 

  • No noted reductions in glucose of HbA1c

Conclusions: Long‐term TTh in men with T2DM and hypogonadism improves glycaemic control and insulin resistance. Remission of diabetes occurred in one‐third of the patients. TTh is potentially a novel additional therapy for men with T2DM and hypogonadism.
