Incidence of Prostate Cancer after Testosterone Therapy for up to 17 years

One of the major concerns among doctors and patients with testosterone therapy is its allegedly negative effect on the prostate.[1] However, according to the current ISA, ISSAM, EAU, EAA, ASA clinical guidelines, there is no conclusive evidence that testosterone therapy increases the risk of prostate cancer or benign prostatic hyperplasia.[2]
 
The guidelines also state that there is also no evidence that testosterone treatment will convert subclinical prostate cancer to clinically detectable prostate cancer.[2]
 
Despite this, many men are being denied testosterone therapy because of undue fears that it would cause harm to the prostate. Here I summarize the results from a study that investigated incidence of prostate cancer with testosterone therapy for up to 17 years.[3]

Multiple beneficial effects of testosterone replacement therapy in men with testosterone deficiency

Alleged concerns regarding risk of cardiovascular disease with testosterone replacement therapy (TRT) have been promulgated recently. However, a large and growing number of intervention studies show to the contrary that TRT reduces cardiovascular risk factors and confers multiple beneficial health effects. Thus, fears promoted by some recent flawed studies need to be critically re-evaluated. 
 
This article gives an overview of studies that have investigated health effects and safety of TRT.[1] As outlined here, the position that testosterone deficiency (TD) should be regarded as a risk factor for cardiovascular disease is supported by a rapidly expanding body of evidence.[2-4]

Testosterone and Prostate Cancer - Bye Androgen Hypothesis, Welcome Saturation Model

 

A long-held belief is that testosterone stimulates development of prostate cancer and/or accelerates its growth. This fear is the most common reason for doctors' reluctance to prescribe testosterone replacement therapy, even in hypogonadal men [1, 2] , which unnecessarily deprives many hypogonadal men of clinical benefits.
 
This summary gives an overview of an in-depth review of current literature regarding the relationship of testosterone levels and prostate cancer, and the effect of testosterone replacement therapy on prostate cancer progression and recurrence.[3] Key studies which have refuted the old belief that testosterone has harmful effects on the prostate are presented, along the new testosterone-prostate paradigm known as the saturation model.
 
Surprisingly, new research provocatively suggests that it is not high testosterone levels that are problematic for prostate cancer, but to the contrary that it is low serum T that is associated with worrisome cancer features and outcomes...and new experimental research has uncovered mechanisms that explain how low testosterone levels may be detrimental for prostate health, and support the new view that testosterone therapy actually may have beneficial effects with regard to prostate cancer...

Is testosterone a friend or a foe of the prostate?

This is an abstract from an interesting debate among leaders in the field of Testosterone and Men's Health. 

INTRODUCTION:

Is there any unequivocal evidence that testosterone (T) can stimulate growth and aggravate symptoms in men with locally advanced and metastatic prostate cancer (PCa)?

This is not a controversial point: the answer is yes.

However, this evidence does not imply that PCa is a result of T or therapy with T (TTh) of hypogonadal men.
