The role of masturbation in the treatment of orgasmic dysfunction

The purpose of this study is to gain understanding of the relationship between ejaculation and serum testosterone level in men. The serum testosterone concentrations of 28 volunteers were investigated daily during abstinence periods after ejaculation for two phases. The authors found that the fluctu …

Classical theories of attitude change point to the positive effect of source expertise on perceived source credibility persuasion, but there is an ongoing societal debate on the increase in anti-elitist sentiments and conspiracy theories regarding the allegedly untrustworthy power elite. In one corr …

Pornography Viewing: Keep Calm and Carry On

This current study examined the effect of a 3-week period of sexual abstinence on the neuroendocrine response to masturbation-induced orgasm. Hormonal and cardiovascular parameters were examined in ten healthy adult men during sexual arousal and masturbation-induced orgasm. Blood was drawn continuou …

Despite the lack of evidence for negative health effects of masturbation, abstinence from masturbation is frequently recommended as a strategy to improve one's sexual self-regulation. We adopted a framework of perceived problems with pornography to collect first hints about whether abstinence from m …

This blog explains what is meant by Type I and Type II errors in statistics (the risk of false positives and false negatives).

Opioids are widely prescribed pain relievers with multiple side effects and potential complications. They produce analgesia via G-protein-protein coupled receptors: μ-, δ-, κ-opioid and opioid receptor-like 1 receptors. Bivalent ligands targeted to the oligomerized opioid receptors might be the key to developing analgesics without undesired side effects and obtaining effective treatment for opioid addicts. In this review we will update the biological effects of μ-opioids on homo- or hetero-oligomerized μ-opioid receptor and discuss potential mechanisms through which bivalent ligands exert beneficial effects, including adenylate cyclase regulation and receptor-mediated signaling pathways.

The opioid crisis has reached epidemic proportions in the United States with rising overdose death rates. Identifying the underlying factors that contribute to addiction vulnerability may lead to more effective prevention strategies. Supply side environmental factors are a major contributing component. Psychosocial factors such as stress, trauma, and adverse childhood experiences have been linked to emotional pain leading to self-medication. Genetic and epigenetic factors associated with brain reward pathways and impulsivity are known predictors of addiction vulnerability. This review attempts to present a biopsychosocial approach that connects various social and biological theories related to the addiction crisis. The emerging role of nutrition therapy with an emphasis on gastrointestinal health in the treatment of opioid use disorder is presented. The biopsychosocial model integrates concepts from several disciplines, emphasizing multicausality rather than a reductionist approach. Potential solutions at multiple levels are presented, considering individual as well as population health. This single cohesive framework is based on the interdependency of the entire system, identifying risk and protective factors that may influence substance-seeking behavior. Nutrition should be included as one facet of a multidisciplinary approach toward improved recovery outcomes. Cross-disciplinary collaborative efforts, new ideas, and fiscal resources will be critical to address the epide...

The Clinical Manual of Addiction Psychopharmacology offers a comprehensive, meticulously detailed review of the pharmacology of addictive drugs and the medications used to treat abuse of and dependence on these addictive drugs. Though rich in detailed background, Clinical Manual of Addiction Psychopharmacology is written with a therapeutic focus, as a clinical guide for the use of pharmacotherapy in patients with substance use disorders.Twenty-four recognized experts cover all major classes of substances that are clinically important in relation to addiction, integrating the basic pharmacology of nine major groups of addictive substances, from alcohol and tobacco to club drugs, with the pharmacology of the drugs used to treat dependence on those addictive substances. The concluding chapter discusses psychosocial treatments combined with pharmacotherapy for alcohol, cocaine, and opioid use disorders.Each thoughtfully illustrated chapter covers the clinical pharmacology of the abused substance, the phenomenology and/or pharmacological treatment of the abstinence syndrome, and the pharmacological treatment for relapse prevention.An essential guide for clinical and social work, the Clinical Manual of Addiction Psychopharmacology will find a wide audience among all prescribing clinicians, psychiatric educators and their students, and other mental health practitioners.
