Testosterone - Men

Testosterone Treatment and Hormonophobia – Cardiovascular risk, the Media, and the Authorities

 
One of the most controversial and debated issue related to testosterone replacement therapy is its effects on cardiovascular risk and related clinical outcomes.
 
In this video presentation, Dr. Morgentaler clarifies misperceptions of testosterone replacement therapy and cardiovascular disease risk, which have created unwarranted concerns and distorted public discussion of testosterone replacement therapy as a medical treatment.

Video Summary of Testosterone Replacement Therapy and Cardiovascular Risk

One of the most controversial and debated issue related to testosterone replacement therapy is its effects on cardiovascular risk and related clinical outcomes.
 
In the February 2015 issue of Mayo Clinic Proceedings a comprehensive medical review paper, written by Dr. Abraham Morgentaler and his coauthors of the Androgen Study Group – www.AndrogenStudyGroup.org - was published.[1]
 
The aim of the review was to analyze all available studies on testosterone replacement therapy and cardiovascular effects, and to clarify the grossly misleading conclusions from two recent studies that caused a tremendous media scare.
 
In this 8 minute video, Dr. Morgentaler presents the key results from this comprehensive analysis…

Health Consequences of Subclinical Testosterone Deficiency - riskier than previously thought

 
In discussions about diagnosis and health consequences of hypogonadism, aka testosterone deficiency, the prime focus is given to testosterone levels and signs/symptoms.[1-3] However, emerging research has identified a less clinically evident gonadal dysfunction called “subclinical” hypogonadism (or “compensated” hypogonadism).[4, 5]
 
Subclinical hypogonadism is characterized by normal testosterone levels in the presence of elevated LH level. As testosterone levels are not markedly reduced in subclinical hypogonadism, intuitively one may think it does not confer negative health consequences.
 
However, a recent study by Corona et al., which specifically was conducted to investigate the potential health ramifications of subclinical hypogonadism, shows that it should not be neglected. Surprisingly, subclinical hypogonadism is associated with an almost 10-fold increased risk of cardiovascular mortality, which is comparable to that for overt hypogonadism! [6]

Testosterone Therapy and Cardiovascular Risk - Advances and Controversies

One of the most debated issues related to testosterone therapy is its effects on cardiovascular risk and clinical events, like for example heart attack.
 
January 27th, 2015 a comprehensive medical review paper was published, addressing the controversial topic of testosterone therapy and cardiovascular risk.[65] It was written by the Androgen Study Group academicians and published in Mayo Clinic Proceedings.
 
Here I summarizes key conclusions from this milestone medical review.

Testosterone, Mortality and Longevity

Population studies show that men with low or low-normal testosterone levels are at an increased risk of mortality compared to those with higher levels, and that cardiovascular disease accounts for the greater proportion of deaths in men with low testosterone.[1] 
 
Here I summarize a medical review paper which addressed the following two questions: [1]
 
1.  Is testosterone deficiency directly involved in the pathogenesis of these conditions or is it merely a biomarker of ill health and the severity of underlying disease processes?
 
2.  Does testosterone replacement therapy retard disease progression and ultimately enhance the clinical prognosis and survival?

Testing for testosterone deficiency - things to know about the blood draw

The first step (aside from identifying symptoms) in diagnosing testosterone deficiency, aka low-T, is to do a blood test.

Here I cover some important practical things to know about a blood draw for testosterone analysis...

Cardiovascular Risks and Elevations of Blood DHT Levels Vary by Testosterone Preparation

 

 

 

The cardiovascular effects of testosterone and testosterone therapy are subject to intense investigation in medical research and have recently generated heated discussions among healthcare professionals. 
 
While the main focus has been on testosterone per se, it is important to remember that testosterone is both a hormone in its own right, and a pro-hormone that gets converted to both estradiol and DHT (dihydrotestosterone). Estradiol and DHT exert effects themselves that are different from the effects of testosterone.
 
Therefore, when analyzing the effects of testosterone, especially supplemental testosterone administered as testosterone replacement therapy, it is critical to take into consideration how it affects downstream testosterone metabolites like estradiol and DHT.
 
Here I will present results from a recent systematic review and meta-analysis that specifically investigated how different routes of testosterone therapy administration (i.e different testosterone preparations) affect blood levels of testosterone and espcially DHT , and how this in turn relates to cardiovascular adverse events.[1]

Testosterone and Fat Loss - the Evidence

 

It is well documented that obesity may cause hypogonadism, and that hypogonadism may cause obesity [1-4] This has generated debate about what condition comes first; obesity or hypogonadism? And what should be the first point of intervention?
 
In this article I will summarize data from several reviews on the associations of hypogonadism and obesity [1-4], and make the case that these conditions create a self-perpetuating vicious circle. Once a vicious circle has been established, it doesn’t matter where one intervenes; one can either treat the obese condition or treat hypogonadism first. The critical issue is to break the vicious circle as soon as possible before irreversible health damage arises. 
 
Nevertheless, as I will explain here, treating hypogonadism first with testosterone replacement therapy may prove to be a more effective strategy because it to a large extent “automatically” takes care of the excess body fat and metabolic derangements. In addition, treating hypogonadism first also confers psychological benefits that will help obese men become and stay more physically active.

Testosterone Therapy Prevents Gain in Intra-Abdominal Fat and Counteracts Loss of Muscle in Non-Obese Aging Men

Testosterone deficiency is especially common in men who are obese and/or have the metabolic syndrome or diabetes, with a prevalence ranging from 35% to almost 80%.[1-5] However, there is a subgroup of non-obese men who have low testosterone levels and suffer from typical symptoms of low-T, but who do not (yet) have any co-morbidities. 
 
Many studies show that suboptimal testosterone levels may contribute to the development of obesity (including abdominal obesity) [6, 7], metabolic syndrome [8-13] and/or diabetes.[9, 14-20] Therefore, testosterone therapy in non-obese men with testosterone deficiency may be an effective intervention to correct not only symptoms associated with hypogonadism, but also prevent the development of obesity, metabolic syndrome and/or diabetes.
 
A notable study was set out to specifically investigate this…
