Low levels of testosterone are manifested by erectile dysfunction, reduced sexual desire, and loss of morning erections with increasing numbers of men are being diagnosed and require treatment. The prevalence rates of testosterone deficiency vary according to different studies but may be as high as 40% in populations of patients with type 2 diabetes. There is increasing evidence that testosterone deficiency is associated with increased cardiovascular and all-cause mortality. Screening for low testosterone is recommended in a number of high risk groups including those with type 2 diabetes and metabolic syndrome. There are recent data to suggest that testosterone replacement therapy may reduce cardiovascular mortality as well as improving multiple surrogate markers for cardiovascular events. Specific clinical trials of testosterone replacement therapy are needed in selected populations but in the meantime we must treat patients based on the best current evidence.

ObjectiveMen with type 2 diabetes are known to have a high prevalence of testosterone deficiency. No long-term data are available regarding testosterone and mortality in men with type 2 diabetes or any effect of testosterone replacement therapy (TRT). We report a 6-year follow-up study to examine the effect of baseline testosterone and TRT on all-cause mortality in men with type 2 diabetes and low testosterone.Research design and methodsA total of 581 men with type 2 diabetes who had testosterone levels performed between 2002 and 2005 were followed up for a mean period of 5.8±1.3 s.d. years. Mortality rates were compared between total testosterone >10.4 nmol/l (300 ng/dl; n=343) and testosterone ≤10.4 nmol/l (n=238). The effect of TRT (as per normal clinical practise: 85.9% testosterone gel and 14.1% intramuscular testosterone undecanoate) was assessed retrospectively within the low testosterone group.ResultsMortality was increased in the low testosterone group (17.2%) compared with the normal testosterone group (9%; P=0.003) when controlled for covariates. In the Cox regression model, multivariate-adjusted hazard ratio (HR) for decreased survival was 2.02 (P=0.009, 95% CI 1.2–3.4). TRT (mean duration 41.6±20.7 months; n=64) was associated with a reduced mortality of 8.4% compared with 19.2% (P=0.002) in the untreated group (n=174). The multivariate-adjusted HR for decreased survival in the untreated group was 2.3 (95% CI 1.3–3.9, P=0.004).ConclusionsLow testosterone levels predict an increase in all-cause mortality during long-term follow-up. Testosterone replacement may improve survival in hypogonadal men with type 2 diabetes.

Background: In men with low levels of testosterone in the blood, it is believed that the symptoms can be regarded as an association between testosterone deficiency syndrome and related comorbidities. Aim: to investigate the effectiveness of testosterone therapy in patients with type 2 diabetes (T2D) and androgen deficiency. Materials and methods: Testosterone replacement therapy was carried out in 26 men with T2D and clinically or laboratory-confirmed androgen deficiency. The age of the subjects ranged from 35 to 69 years old. Laboratory studies included determinations of the concentration of the hormones estradiol, luteinizing hormone (LH), and prostate-specific antigen (PSA). The observation period was 9 months. Results: The average level of total blood testosterone in the subjects before treatment was 9.4 mol/l and was likely lower than that of the control group (19.3 ± 1.6 nmol/l). The levels of total testosterone in the subjects ranged from 3.9 nmol/l to 10.7 nmol/l, and hormone levels measuring less than 8.0 nmol/l were observed in only 11 patients. After a course of testosterone replacement therapy, a stabilization in total testosterone levels at the level of reference values (as compared to the start of treatment) was observed in the blood of men with T2D after 9 months of observation and the administration of the fourth injection (16.83 ± 0.75 nmol/l). Conclusion: The use of long-acting injectable testosterone undecanoate leads to normalization of total testosterone levels in the blood of men with T2D and androgen deficiency, and LH levels in these patients are unlikely to change.

History Of

We report the case of a 45-year-old man with a history of Klinefelter syndrome undergoing testosterone replacement therapy, and with type 2 diabetes treated with metformin with poor metabolic control. When vildagliptin was added to his treatment, he presented hypoglycemia after the testosterone injection. We highlight this not widely reported drug interaction between hypoglycemic agents and testosterone.
