چکیده
Testosterone (T) is not just another hormone: it is endocrinologic dynamite. Testosterone supplementation at low levels is passionately and controversially discussed among health care professionals and lay people alike, giving it a cultural, social and even a political dimension. The problem arises with decreasing levels. With an incidence of 6% in middle-aged men [1], late-onset hypogonadism (aka: PADAM = Partial Androgen Deficiency of the Aging Male) can be frequently discovered in clinical practice. Unfortunately, the relationship between serum testosterone levels and clinical symptoms is a bit hazy. It appears that a substantial proportion of men with low T lack clinical symptoms whereas a high number of men with clinical symptoms have T levels within the normal range. However, the likelihood of symptoms increases with decreasing testosterone [2]. Facing PADAM, second thoughts regarding treatment seem to be commonplace. Is replacement really necessary? Isn’t there more harm than good to it? Definite randomized controlled trials to answer these questions are lacking, so uncertainty lays the ground for speculations. Fueled by many sources, including the media, testosterone is about to become the villain of hormones. The negative connotations include fear of cancer, images of doping scandals, of humongous body builders or the money-greedy pharmaceutical industry. In February this year, the New York Times wrote: “Drug companies have shamelessly pushed the notion, to doctors and to the public, that their testosterone-boosting product can overcome a supposed disease called ‘low T,’ which is characterized by feelings of fatigue, loss of sexual drive, depressed moods, an increase in body fat and decrease in muscle strength, among other symptoms” [3].

Gains from diversification on convex combinations: A majorization and stochastic dominance approach
By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...
متن کاملImproved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.
BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...
متن کاملSteady electrodiffusion in hydrogel-colloid composites: macroscale properties from microscale electrokinetics.
A rigorous microscale electrokinetic model for hydrogel-colloid composites is adopted to compute macroscale profiles of electrolyte concentration, electrostatic potential, and hydrostatic pressure across membranes that separate electrolytes with different concentrations. The membranes are uncharged polymeric hydrogels in which charged spherical colloidal particles are immobilized and randomly d...
متن کاملPerturbative Analysis of Dynamical Localisation
In this paper we extend previous results on convergent perturbative solutions of the Schrödinger equation of a class of periodically timedependent two-level systems. The situation treated here is particularly suited for the investigation of two-level systems exhibiting the phenomenon of (approximate) dynamical localisation. We also present a convergent perturbative expansion for the secular fre...
متن کاملCollinear contextual suppression
The context of a target can modulate behavioral as well as neural responses to that target. For example, target processing can be suppressed by iso-oriented surrounds whereas it can be facilitated by collinear contextual elements. Here, we present experiments in which collinear elements exert strong suppression whereas iso-oriented contextual surrounds yield no contextual modulation--contrary t...
