A small number of drugs have been approved by the Food & Drug Administration (FDA) for weight loss. Liraglutide, Tirzepatide, and Semaglutide are GLP-1 agonists and anti-diabetic drugs, and are some of the latest FDA-approved medications for weight loss. Up to 50% of patients experience gastrointestinal (GI) distress, a common side effect, while taking these medications. Other side effects include tachycardia, antibody-mediated angioedema, anaphylaxis, irritation at the injection site, and hypoglycemia. However, very little is known regarding sexual dysfunction as a side effect of GLP-1 agonists. The following case report discusses the potential negative impact on sexual function of these widely prescribed anti-diabetic, weight loss medications.

Other mechanisms of GLP-1 agonist-induced anorgasmia may involve their signaling in the brain due to their presence in the hypothalamus. GLP-1 receptor modulation in the hypothalamus may decrease dopamine and norepinephrine signaling, which are neurotransmitters crucial for motivation, pleasure, and orgasm as well as disrupt pathways involved in sexual desire and arousal.</p><p><strong>Conclusion: </strong>Further investigation on the prevalence of sexual dysfunction with GLP-1 agonists and their mechanism of action is needed.</p>","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"13 3","pages":"qfaf047"},"PeriodicalIF":2.6,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12260840/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144643287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Efficacy of Chinese herbal medicine in the treatment of anxiety and depression in male sexual dysfunction: a systematic review and meta-analysis.","authors":"Zhaozhan Xie, Jinxian Lu, Xuecheng Zhang, Hongling Jia, Yongchen Zhang","doi":"10.1093/sexmed/qfaf048","DOIUrl":"10.1093/sexmed/qfaf048","url":null,"abstract":"&lt;p&gt;&lt;strong&gt;Background: &lt;/strong&gt;Male Sexual Dysfunction (MSD), comprising erectile dysfunction (ED) and premature ejaculation (PE), exhibits an age-related prevalence affecting 50% of males beyond their fourth decade. Beyond physiological manifestations, MSD with comorbid anxiety and depression exerts profound psychosocial impacts. Emerging evidence suggests Chinese Herbal Medicine (CHM) may offer therapeutic potential for addressing this clinical intersection.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Aim: &lt;/strong&gt;To systematically assess the efficacy of CHM on alleviating anxiety and depression in patients with MSD via a comprehensive systematic review and meta-analysis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This study systematically searched four Chinese databases (China National Knowledge Infrastructure, Wanfang Database, China Biomedical Database, and VIP Database) and four international databases (PubMed, Web of Science, EMBASE, and Cochrane Library). Randomized controlled trials (RCTs) investigating CHM interventions for MSD with comorbid anxiety and depression were identified.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Outcomes: &lt;/strong&gt;The primary outcome focused on changes in symptoms of anxiety and depression, while secondary outcomes encompassed overall male sexual function improvement.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;By synthesizing data from 12 RCTs involving 1050 participants, our findings provide the first robust evidence that CHM significantly alleviates anxiety and depression in MSD, while concurrently improving core symptoms of MSD, such as PE and ED. Notably, CHM formulations demonstrated superior efficacy over SSRIs in improving both psychological scales, including Self-Rating Anxiety Scale [MD = -9.11, 95% CI (-11.53, -6.70), &lt;i&gt;P&lt;/i&gt; &lt; .05], Self-Rating Depression Scale [MD = -9.85, 95% CI (-14.07, -5.63), &lt;i&gt;P&lt;/i&gt; &lt; .05], the Hamilton Depression Rating Scale (HAMD) [MD = -5.30, 95% CI (-11.61, 1.01), &lt;i&gt;P&lt;/i&gt; &gt; .05], and the Hamilton Anxiety Rating Scale [MD = -3.89, 95% CI (-4.52,-3.27), &lt;i&gt;P&lt;/i&gt; &lt; .05], as well as MSD-specific metrics, such as International Index of Erectile Function-5 [MD = 3.26, 95% CI (1.98, 4.53), &lt;i&gt;P&lt;/i&gt; &lt; .05] and intravaginal ejaculation latency time [MD = 1.60, 95% CI (0.82, 2.37), &lt;i&gt;P&lt;/i&gt; &lt; .05].

{"title":"Psychometric evaluation and measurement invariance of the Sexual and Relationship Distress Scale in cancer and nonclinical general reproductive-age populations.","authors":"Yanfei Jin, Yang Li, Lina Xiong, Chulei Tang, Hongwen Ma","doi":"10.1093/sexmed/qfaf041","DOIUrl":"10.1093/sexmed/qfaf041","url":null,"abstract":"&lt;p&gt;&lt;strong&gt;Background: &lt;/strong&gt;The Sexual and Relationship Distress Scale (SaRDS) is a validated instrument developed in English to assess intra-personal and inter-personal distress experienced by individuals and their partners in the context of sexual dysfunction. However, it has not yet been translated into Chinese nor psychometrically evaluated within Chinese clinical cancer and nonclinical populations.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This study aimed to translate the SaRDS into Chinese and assess its psychometric properties and measurement invariance across different populations (colorectal cancer [CRC] patients vs. nonclinical general reproductive-age adults) and across gender groups (male vs. female).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Three phases were undertaken: (a) transcultural adaptation, (b) pre-testing, and (c) psychometric evaluation. Transcultural adaptation included translations and expert panels, the pre-testing was conducted in 20 participants. The psychometric evaluation was tested among 486 CRC patients and 536 nonclinical general reproductive-age populations.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Outcomes: &lt;/strong&gt;The Chinese version of the SaRDS was consistent with the original version, including 30 items and 14 factors.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Confirmatory factor analysis supported the 14-factor structure of the original SaRDS construct. The composite reliability and the average variance extracted indicated the SaRDS had good convergent validity. Measurement invariance analyses indicated that the factor structure, factor loadings, and item intercepts of the SaRDS were invariant across CRC and nonclinical general populations, as well as across gender groups. The correlation of SaRDS with the Arizona Sexual Experience Scale and the Quality of Relationship Index showed good criterion-related validity. Moreover, the SaRDS and subscales had high internal consistency.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Clinical implications: &lt;/strong&gt;The Chinese version of the SaRDS is a psychometrically robust tool suitable for evaluating individual and relationship distress related to sexual dysfunction among clinical cancer and nonclinical general populations. The 14 domains provided by the SaRDS enable clinicians to identify specific areas of distress, facilitating accurate assessment and tailored interventions for individuals and couples experiencing sexual difficulties.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Strengths and limitations: &lt;/strong&gt;This study provides the first evidence of measurement invariance of the SaRDS across cancer patients, nonclinical general populations, and gender groups. However, due to its cross-sectional design, future longitudinal studies are needed to further examine the temporal stability and measurement invariance over time.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Our findings suggest that the Chinese version of the SaRDS is a reliable, valid, and psychometrically sound instrument for assessing sexual and relationship distress in clinical cancer and nonclinical reproductive-","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"13 3","pages":"qfaf041"},"PeriodicalIF":2.6,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12128924/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
