Symptoms of male hypogonadism such as low libido and erectile dysfunction (ED) respond to testosterone (T) replacement. In hypogonadal men with major depressive disorder (MDD), the extent to which T replacement alleviates sexual symptoms of hypogonadism is not known. We conducted 6 week double-blind placebo-controlled clinical trial in men with low and low-normal T levels (i.e., total T <or= 350 ng/dl) and MDD. Men were randomized to receive weekly intramuscular injections of either T enanthate 200 mg or sesame-seed oil (placebo). The primary outcome measure was self-reported sexual functioning. We randomized 30 patients. The mean age was 52(SD +/- 8) years, mean T level 262.5(SD +/- 8) ng/dl, and mean baseline Hamilton Rating Scale for Depression (HAM-D) score 21(SD +/- 8). At baseline, sexual function was low, with the majority reporting having had normal erectile and orgasmic functioning 0-1 time in the preceding month. All patients who received T achieved normalization of their T levels. The HAM-D scores decreased significantly in both T and placebo groups, and there were no significant between-group differences: reduction in mean HAM-D score from baseline to endpoint was 10.1 in patients who received T and 10.5 in those who received placebo. Self-reported sexual functioning improved slightly in both groups; a between-group difference was not detected. Both T replacement and placebo were associated with improvement in sexual function and mood, but differences between T and placebo were not distinguishable.
    • "These symptoms overlap with disease characteristics of major depres- sion [3,4]. Testosterone treatment can enhance several aspects of mood and cognition in hypogonadal men [5], it normalizes synaptic neurogenesis, and it reduces depressive symptoms [6]. Still, the role of reduced androgens in psychiatric problems, such as mood disorders, remains largely unknown. "
    [Show abstract] [Hide abstract] ABSTRACT: Steroid hormones like androgens play an important role in the development and maintenance of several brain functions. Androgens can act through androgen receptors (AR) in the brain. This study aims to demonstrate the feasibility of positron emission tomography (PET) with 16β-[(18)F]fluoro-5α-dihydrotestosterone ([(18)F]FDHT) to image AR expression in the brain. Male Wistar rats were either orchiectomized to inhibit endogenous androgen production or underwent sham-surgery. Fifteen days after surgery, rats were subjected to a 90-min dynamic [(18)F]FDHT PET scan with arterial blood sampling. In a subset of orchiectomized rats, 1mg/kg dihydrotestosterone was co-injected with the tracer in order to saturate the AR. Plasma samples were analyzed for the presence of radioactive metabolites by radio-TLC. Pharmacokinetic modeling was performed to quantify brain kinetics of the tracer. After the PET scan, the animals were terminated for ex-vivo biodistribution. PET imaging and ex vivo biodistribution studies showed low [(18)F]FDHT uptake in all brain regions, except pituitary. [(18)F]FDHT uptake in the surrounding cranial bones was high and increased over time. [(18)F]FDHT was rapidly metabolized in rats. Metabolism was significantly faster in orchiectomized rats than in sham-orchiectomized rats. Quantitative analysis of PET data indicated substantial spill-over of activity from cranial bones into peripheral brain regions, which prevented further analysis of peripheral brain regions. Logan graphical analysis and kinetic modeling using 1- and 2-tissue compartment models showed reversible and homogenously distributed tracer uptake in central brain regions. [(18)F]FDHT uptake in the brain could not be blocked by endogenous androgens or administration of dihydrotestosterone. The results of this study indicate that imaging of AR availability in rat brain with [(18)F]FDHT PET is not feasible. The low AR expression in the brain, the rapid metabolism of [(18)F]FDHT in rats and the poor brain penetration of the tracer likely contributed to the poor performance of [(18)F]FDHT PET in this study.

    • "There were relatively few PSDs, not covered by the recent scientific literature.Table 3 summarizes these outcomes. Emotional functions242526, energy and drive functioning272829, cognitive functions303132, employment333435, and relationship with the others363738 were the most common psychosocial problems emerging both in the literature and the patients' answers. The frequency of the appearance of PSDs was also comparatively identical. "
    [Show abstract] [Hide abstract] ABSTRACT: Despite all the knowledge on depression, it is still unclear whether current literature covers all the psychosocial difficulties (PSDs) important for depressed patients. The aim of the present study was to identify the gaps in the recent literature concerning PSDs and their related variables. Psychosocial difficulties were defined according to the World Health Organization International Classification of Functioning, Disability and Health (ICF). A comparative approach between a systematic literature review, a focus group, and individual interviews with depressed patients was used. Literature reported the main psychosocial difficulties almost fully, but not in the same degree of importance as patients' reports. Furthermore, the covered areas were very general and related to symptomatology. Regarding the related variables, literature focused on clinical variables and treatments above all but did not report that many psychosocial difficulties influence other PSDs. This study identified many existing research gaps in recent literature mainly in the area of related variables of PSDs. Future steps in this direction are needed. Moreover, we suggest that clinicians select interventions covering not only symptoms, but also PSDs and their modifiable related variables. Furthermore, identification of interventions for particular psychosocial difficulties and personalisation of therapies according to individuals' PSDs are necessary.

    • "Seidman and Roose [84] Double At the end of the double-blind phase, testosterone-treated men had a greater reduction in HAM-D scores and a higher remission rate of subthreshold depression (52.9% versus 18.8%) than did placebo-treated men. At the end of the extension phase, there were no significant between-group differences in the remission rate of depression between the original testosterone group and the original placebo group (58.8% versus 68.8%, resp.). "
    [Show abstract] [Hide abstract] ABSTRACT: The aim of this review was to summarize current knowledge on the correlation between depressive symptoms with a syndrome called partial androgen deficiency of the aging male (PADAM) and on the potential benefits of testosterone (T) treatment on mood. Despite, the causative nature of the relationship between low T levels and depression is uncertain, many hypogonadal men suffer from depression and vice versa several depressed patients are affected by hypogonadism. Supplementation with testosterone failed to show sound evidence of effectiveness in the treatment of depression. Nevertheless, testosterone supplementation has proved to be effective on some domains significant for the quality of life of aged patients with PADAM (sexual function and cognitive functions, muscular strengths).
