男性性功能障碍
  • 文章类型: Case Reports
    性高潮是一种鲜为人知的现象,被定义为终身或获得性持续无法实现射精。尽管性高潮普遍存在,目前尚无确定的治疗方法。
    报告一个终生性高潮患者的独特病例,该患者通过标签外使用氟班色林能够达到他的第一次性高潮。
    本病例研究依赖于患者的自我报告和相关文献的回顾。患者提供书面知情同意书。
    一位28岁的男性出现在我们办公室,抱怨终生性高潮,没有任何勃起功能障碍的迹象。他报告性欲和能量水平良好,否认有任何泌尿症状或抑郁症史。该患者因使用多种标签外药物而未能通过医疗管理,包括安非他酮和bremelanotide.尽管在3个月内接受了4到5次性治疗,患者报告这种治疗方法无效.然后开始使用氟班色林,在4周内给28到32次剂量后,他第一次达到了性高潮.值得注意的是,患者出现夜尿症和失眠。随访国际勃起功能指数得分略有提高2分,总体满意度子域没有任何改善。
    这个案例突出了年轻男性患者治疗性高潮和射精的挑战。涉及药物治疗和性治疗的逐步方法不成功。然而,标签外使用氟班色林最终导致患者达到了他的第一次性高潮,尽管有一些副作用。需要进一步的研究来评估氟班色林在该适应症中的疗效和安全性。
    UNASSIGNED: Anorgasmia is a poorly understood phenomenon defined as either a lifelong or acquired consistent inability to achieve ejaculation. Despite the prevalence of anorgasmia, there is currently no established treatment for the condition.
    UNASSIGNED: To report a unique case of a patient with lifelong anorgasmia who was able to achieve his first orgasm with off-label use of flibanserin.
    UNASSIGNED: The present case study relies on the patient\'s self-report and a review of the relevant literature. The patient provided written informed consent.
    UNASSIGNED: A 28-year-old male presented to our office with complaints of lifelong anorgasmia, without any signs of erectile dysfunction. He reported good libido and energy levels and denied any urinary symptoms or history of depression. The patient failed medical management with numerous off-label medications, including bupropion and bremelanotide. Despite having received 4 or 5 sex therapy sessions over 3 months, the patient reported that this treatment approach was not effective. Off-label use of flibanserin was then initiated, and after 28 to 32 doses over 4 weeks, he achieved his first orgasm. Notably, the patient experienced nocturia and insomnia. The follow-up International Index of Erectile Function score marginally improved by 2 points without any improvement in the overall satisfaction subdomain.
    UNASSIGNED: This case highlights the challenges of managing anorgasmia and anejaculation in a young male patient. A stepwise approach involving pharmacotherapy and sex therapy was not successful. However, the off-label use of flibanserin ultimately resulted in the patient achieving his first orgasm, albeit with some side effects. Further studies are needed to evaluate the efficacy and safety of flibanserin in men for this indication.

    背景:性功能被认为是人类生活和生活质量的重要组成部分。性功能问题可能是痛苦的根源,较低的自尊,和较低的生活质量。早期发现医疗合并症可以显着降低对性功能的影响。在沙特阿拉伯,调查医学合并症与男性性功能障碍(MSD)之间关联的研究有限.因此,我们的目标是填补这个知识空白。
    目的:本研究旨在分析和阐述三级医院的所有MSD病例,在吉达,沙特阿拉伯从2016年到2021年。
    方法:这是一项横断面回顾性研究。回顾性分析了2016年至2021年诊断为MSD的321例患者的病历。年龄,性别,性功能障碍的类型,合并症,和血脂谱是从患者的计算机化医疗记录中获得的一些因素。
    结果:研究人群包括321名MSD男性,平均年龄约53岁(SD=11.5)。在性功能障碍模式中,仅在279例(86.9%)患者中发现勃起功能障碍(ED)。169例(52.8%)患者的ED持续时间为1至5年。大多数患者(196,61.1%)患有轻度ED。医学原因见于278例(80.4%)患者。最常见的合并症是179例(55.8%)患者的糖尿病(DM),高血压(HTN)155(48.2%)患者,113例(35.2%)患者血脂异常。吸烟不是ED的危险因素。患有严重ED的风险与特发性原因有关,HTN,DM,缺血性心脏病(IHD)。ED持续时间长的风险与ED的特发性原因和高血清肌酐水平有关。
    结论:结论:诊断为DM的患者,HTN,和IHD在经历严重形式的ED的风险更大。对于DM患者来说,保持勃起功能至关重要,HTN,和IHD,因为这与严重ED有关。
    BACKGROUND: Sexual functionality is considered a vital component of human life and quality of life. Issues with sexual functionality can be a source of distress, lower self-esteem, and lower quality of life. Early detection of medical comorbidities can significantly lower the effect on sexual function. In Saudi Arabia, studies investigating the association between medical comorbidities and male sexual dysfunction (MSD) are limited. Therefore, our goal was to fill this knowledge gap.
    OBJECTIVE: This study aimed to analyze and elaborate on all cases of MSD at a tertiary hospital, in Jeddah, Saudi Arabia from 2016 to 2021.
    METHODS: This is a cross-sectional retrospective study. The medical records of 321 patients diagnosed with MSD from 2016 to 2021 were reviewed retrospectively. The age, sex, type of sexual dysfunction, comorbidities, and lipids profile were some of the factors obtained from the patient\'s computerized medical records.
    RESULTS: The study population included 321 men with MSD and a mean age of approximately 53 years (SD=11.5). Among the sexual dysfunction pattern, only erectile dysfunction (ED) was found in 279 (86.9%) patients. ED duration lasted one to five years in 169 (52.8%) patients. Most of the patients (196, 61.1%) had mild ED severity. Medical causes were seen in 278 (80.4%) patients. The most frequent comorbidities were diabetes mellitus (DM) in 179 (55.8%) patients, hypertension (HTN) in 155 (48.2%) patients, and dyslipidemia in 113 (35.2%) patients. Smoking was not a risk factor for ED. The risk of having a severe form of ED was associated with idiopathic causes, HTN, DM, and ischemic heart disease (IHD). The risk of having a long duration of ED was related to idiopathic causes of ED and high serum creatinine levels.
    CONCLUSIONS:  In conclusion, patients diagnosed with DM, HTN, and IHD are at greater risk to experience a severe form of ED. It is crucial to keep erection function in mind for patients with DM, HTN, and IHD as this is associated with severe ED.

    正念方面可以通过结构化的正念干预来训练,但对于性治疗中更广泛的应用知之甚少(例如,男性,伴侣和不同的性功能障碍)。
    为了评估为期8周的干预措施的可行性和初步疗效,对于性和亲密关系(MSIR)的正念-作为常规治疗(TAU)的补充,而在有或没有伴侣的男性和女性的临床样本中,仅与TAU相比。
    在这项随机对照可行性研究中,34名参与者被随机分配到MSIR+TAU(n=15)或TAU(n=19)。该研究还包括六个健康伴侣。MSIR作为2个个体评估和6个2小时的混合性别和不同类型的性功能障碍的小组会议进行。
    主要结果指标如下:(1)可行性,定义为实施招聘,接受,和参与日常临床实践和MSIR完成率的干预;(2)性功能,根据视觉模拟量表(“受问题困扰”)和经过验证的问卷(女性和男性性功能问卷的变化,女性性功能指数,女性性困扰量表,国际勃起功能指数)。
    MSIR是可行的,并且受到患者的好评,接受和干预完成率高。与预处理相比,MSIR+TAU组和TAU对照组在治疗结束时受到性问题的困扰明显较少,但MSIR+TAU组的变化明显更大(P=.04).MSIR+TAU组的参与者没有收到比TAU组少的TAU会话(MSIR+TAU意味着,6个会议;TAU是指,8个会议)。
    MSIR可以有效地用于临床,作为TAU的附加药物,用于治疗女性和男性性功能障碍和健康伴侣。
    这项研究的主要优势在于它是一项随机对照研究。这项研究是新颖的,因为它包括同一正念组中具有不同类型性功能障碍的男性和女性。局限性包括研究的试点性质(例如样本量小),统计结论要谨慎。在更大的样品中可以发现更准确的结果。
    这项研究的结果支持现有的证据,表明基于正念的干预措施对于针对男性和女性的性功能障碍是可行和有效的。
    UNASSIGNED: Mindfulness facets can be trained with structured mindfulness interventions, but little is known regarding application on a broader level within sex therapy (e.g. men, partners and different sexual dysfunctions).
    UNASSIGNED: To evaluate the feasibility and preliminary efficacy of an 8-week intervention-specifically, mindfulness for sex and intimacy in relationships (MSIR)-as a supplement to treatment as usual (TAU) as compared with only TAU in a clinical sample of men and women referred for sexual difficulties with or without a partner.
    UNASSIGNED: In this randomized controlled feasibility pilot study, 34 participants were randomized to MSIR + TAU (n = 15) or TAU (n = 19). Six healthy partners were also included in the study. MSIR was administered as 2 individual evaluations and six 2-hour group sessions of mixed gender and different types of sexual dysfunction.
    UNASSIGNED: The primary outcome measures were as follows: (1) feasibility, defined as the implementation of recruitment, acceptance, and attendance of intervention in daily clinical practice and the MSIR completion rate; (2) sexual functioning, as measured on a visual analog scale (\"bothered by problem\") and by validated questionnaires (Changes in Sexual Function Questionnaire for Females and Males, Female Sexual Function Index, Female Sexual Distress Scale, International Index of Erectile Function).
    UNASSIGNED: MSIR was feasible and well received by patients, with high rates of acceptance and intervention completion. As compared with pretreatment, the MSIR + TAU group and TAU control group were significantly less bothered by their sexual problems at the end of treatment, but the change was significantly larger in the MSIR + TAU group (P = .04). Participants in the MSIR + TAU group did not receive fewer TAU sessions than the TAU group (MSIR + TAU mean, 6 sessions; TAU mean, 8 sessions).
    UNASSIGNED: MSIR could be effectively used in a clinical setting as an add-on to TAU in the treatment of female and male sexual dysfunction and healthy partners.
    UNASSIGNED: The major strength of the study is that it is a randomized controlled study. This study is novel in the sense that it included men and women with different types of sexual dysfunction in the same mindfulness group. Limitations include the pilot nature of the study (e.g. a small sample size), and statistical conclusions should be made with caution. More accurate results may be found in a larger sample.
    UNASSIGNED: Results from this study support already existing evidence that mindfulness-based interventions are feasible and effective for targeting sexual dysfunctions in men and women.

    勃起障碍(ED)是在性交过程中连续或重复地无法达到勃起或保持足够长的时间。鉴于利用高质量临床实践指南(CPGs)诊断ED的重要性,研究小组对勃起障碍CPGs进行了范围审查,以解决基于最佳质量临床指南的问题.这项范围界定审查分五个步骤进行:1-确定研究问题,2-识别相关研究,3-选择研究,4-数据提取,5-总结和报告结果。最初的搜索产生了1888篇文章,CPG和书籍,但经过两名评估师的一级和二级筛选,提取9个CPGs。之后,两位评估师使用AGREEII工具检查了这些指南的质量。最终,提取5个CPGs。在回顾了5条准则后,回答了5个问题。总的来说,在回答标记的问题时,CPG有理想的重叠;然而,在细节上也有一些差异。这篇评论表明,检查受影响个人的首要原则是完整详细的历史,然后进行身体检查并使用相关问卷来完成诊断问题所需的信息。下一步是进行常规实验室测试;也可以检查荷尔蒙概况,如果有必要,应根据个人条件进行特殊测试。
    Erectile disorder (ED) is the continuous or repeated inability to achieve an erection or maintain its firmness for an adequate amount of time during sexual intercourse. Given the importance of utilizing quality clinical practice guidelines (CPGs) for the diagnosis of ED, the research team conducted a scoping review of erectile disorder CPGs to address the questions based on the clinical guideline of the best quality. This scoping review was conducted in five steps: 1 - identification of the research question, 2 - identification of relevant studies, 3 - selection of studies, 4 - data extraction, 5 - summarizing and reporting the results. The initial search yielded 1,888 articles, CPGs and books but after primary and secondary screening by two appraisers, 9 CPGs were extracted. After that, the two appraisers examined the quality of these guidelines using the AGREE II tool. Eventually, 5 CPGs extracted. After reviewing 5 guidelines, 5 questions were answered. Overall, the CPGs had desirable overlap in response to the marked questions; nevertheless, there were some differences in details too. This review shows that the first and foremost principle in examining the affected individuals is taking a complete detailed history, followed by a physical examination and use of relevant questionnaires to complete the information necessary to diagnose the problem. The next step is to perform routine lab tests; hormonal profiles may also be checked, and if necessary, special tests should be performed based on an individual\'s conditions.

    生育率,一个社会,文化,和医疗问题,已经引起了公众的关注,因为它具有预测未来健康的潜力。近年来,男性不育的发病率明显上升,和各种危险因素,比如先天因素,后天因素,和特发性因素,导致了这种情况。男性不育会导致患者严重的心理和社会困扰。随着二孩政策的实施,男性不育症给患者和医疗系统带来了巨大的心理和社会压力以及巨大的经济负担。这不仅引起了育龄男性的注意,也引起了许多男性专家的注意。治疗男性不育的常规治疗方法,包括毒品,精索静脉曲张手术,宫腔内人工授精,体外受精,卵胞浆内精子注射,可以在一定程度上恢复生育能力,但是它们的功效远远不能令人满意,更不用说一些不良事件了。因此,许多男性选择针灸来治疗他们的不孕症,并产生了显著的效果。在本论文中,从调节激素分泌,减少炎症,改善精液参数。现有文献表明,针刺可有效治疗男性不育症。
    Fertility, a social, cultural, and medical issue, has aroused public attention because of its potential to predict future health. In recent years, the incidence of male infertility has increased significantly, and various risk factors, such as congenital factors, acquired factors, and idiopathic factors, have led to this situation. Male infertility causes substantial psychological and social distress in patients. With the implementation of the two-child policy, male infertility has brought enormous psychological and social pressure and huge economic burden to patients and the healthcare system. This has attracted the attention of not only men of childbearing age but also many male experts. The conventional therapeutic approaches for treating male infertility, including drugs, varicocele surgery, intrauterine insemination, in vitro fertilization, and intracytoplasmic sperm injection, can restore fertility to a certain extent, but their efficacy is far from satisfactory, not to mention some adverse events. Therefore, acupuncture has been chosen by many men to treat their infertility and produced significant effects. In the present paper, the efficacy and mechanism of acupuncture in the treatment of male infertility were analyzed from different perspectives such as regulating hormone secretion, reducing inflammation, and improving semen parameters. The existing literature shows that acupuncture can effectively treat male infertility.

    The metabolic disorders caused by diabetes can lead to various complications, including dysfunction of the male reproductive system. In patients with diabetes, long-term hyperglycemia results in diabetic vascular neuropathy, oxidative stress injury, abnormal zinc metabolism, and insulin resistance syndrome. In addition, insulin deficiency and resistance in diabetes can damage the hypothalamus, pituitary gland, gonads, and perigonads. This can reduce the secretion of sex hormones including gonadotropin-releasing hormone, follicle stimulating hormone, luteinizing hormone, and testosterone, and can lead to testicular atrophy, stromal cell atrophy, seminiferous tubule damage, spermatogenic cell damage, and other structural injuries of the male reproductive organs. These actions can affect male fertility and reproductive health. Herein, we review studies that report a causative role of diabetes in male reproductive function. We also discuss the evidence-based mechanisms involved in the processes of diabetes-related male sexual and reproductive dysfunction as well as the progress in treatment.

    背景:在男性性功能障碍中,勃起功能障碍和早期射精的患病率最高。这里,我们测试了二甲磺酸盐(Vyas®)对早期射精的影响.为此,我们在男性早泄患者中进行了一项双盲随机临床试验.
    方法:共有46名男性射精早(平均年龄:35.23岁),婚姻关系稳定,每周有规律的阴茎-阴道性交,被随机分配到lisdexamfetaminedimesylate状态(30mg)或安慰剂状态。在预期的阴茎-阴道性交之前约6小时服用化合物。在基线和四周后研究结束时,参与者完成了一系列涵盖早期射精的自评问卷.女性伴侣还对参与者的早期射精情况进行了评分。
    结果:与安慰剂条件相比,在lisdexamfetamine条件下,早期射精的尺寸随着时间的推移而改善,尽管在安慰剂条件下也观察到改善。
    结论:在具有稳定婚姻关系且每周有规律的阴茎-阴道性交的男性成年人中,lisdexamfetaminedimesylate改善早期射精的尺寸。鉴于在安慰剂条件下也观察到改善,应考虑心理因素,例如对早期射精的关注和对化合物的良好期望。
    BACKGROUND: Among male sexual dysfunctions, erectile dysfunction and early ejaculation have the highest prevalence rates. Here, we tested the influence of lisdexamfetamine dimesylate (Vyas®) on early ejaculation. To this end, we performed a double-blind randomized clinical trial among males with early ejaculation.
    METHODS: A total of 46 males with early ejaculation (mean age: 35.23 years) and in stable marital relationships with regular weekly penile-vaginal intercourse were randomly assigned either to the lisdexamfetamine dimesylate condition (30 mg) or to the placebo condition. Compounds were taken about six hours before intended penile-vaginal intercourse. At baseline and four weeks later at the end of the study, participants completed a series of self-rating questionnaires covering early ejaculation. Female partners also rated participants\' early ejaculation profile.
    RESULTS: Compared to the placebo condition, dimensions of early ejaculation improved over time in the lisdexamfetamine condition, though improvements were also observed in the placebo condition.
    CONCLUSIONS: Among male adults in stable marital relationships with regular weekly penile-vaginal intercourse, lisdexamfetamine dimesylate improved dimensions of early ejaculation. Given that improvements were also observed in the placebo condition, psychological factors such as increased attention to early ejaculation and favorable expectations of the compound should be considered.

    背景:本研究旨在探讨冲击波碎石术(SWL)治疗输尿管近端结石对男女患者性功能的影响。
    方法:在这项前瞻性研究中,对2019年8月至2020年10月在我们的诊所接受SWL治疗的30名女性和72名男性患者进行了评估。CT,肌酐,尿路分析,在所有患者的初始会诊期间进行培养。关于年龄的信息,BMI,并记录患者的结石负担。男性患者回答了国际勃起功能指数-5(IIEF-5)问卷,女性参与者回答女性性功能指数(FSFI)3次:手术前和手术后第一个月和第三个月。第一个月重复CT,并注意到任何残留物。
    结果:手术前男性患者的平均IIEF-5评分为23.11±8.11,第一个月下降到19.74±7.65,第三个月下降到23.88±9.23,p=0.001。女性患者的平均FSFI评分为18.2±9.9,第一个月下降到12.8±6.12,第三个月下降到17.8±8.66,p=0.001。单因素分析显示,患者年龄(男性:p=0.004,女性:p=0.008)和BMI(男性:p=0.044,女性:p=0.027)与两种性别的较差评分相关。然而,关于结石负荷没有任何显著发现(男性:p=0.054,女性:p=0.078).
    结论:对于接受SWL治疗的患者,应考虑发生暂时性性功能障碍的可能性。随着患者年龄和BMI的增加,SWL相关的性功能障碍变得更加严重。
    BACKGROUND: This study aims to investigate the effects of shock wave lithotripsy (SWL) treatment for proximal ureteral stones on the sexual functions of patients of both genders.
    METHODS: In this prospective study, 30 female and 72 male patients who had received SWL treatment for proximal ureteral stones in our clinic between August 2019 and October 2020 were evaluated. CT, creatinine, urinary analysis, and culture were performed during the initial consultation for all patients. Information regarding the age, BMI, and stone burden of the patients was recorded. Male patients answered the International Index of Erectile Function-5 (IIEF-5) questionnaire, and female participants answered the Female Sexual Function Index (FSFI) 3 times: pre-procedural and post-procedural first and third month. CT was repeated on the first month, and any residues were noted.
    RESULTS: The mean IIEF-5 scores of the male patients were 23.11 ± 8.11 prior to surgery, and it decreased to 19.74 ± 7.65 in the first month and 23.88 ± 9.23 in the third, p = 0.001. The mean FSFI scores of female patients were 18.2 ± 9.9, which decreased to 12.8 ± 6.12 in the first month and 17.8 ± 8.66 in the third, p = 0.001. Univariate analysis revealed that the patients\' age (male: p = 0.004 and female: p = 0.008) and BMI (male: p = 0.044 and female: p = 0.027) were related to the poorer scores for both genders. However, there were not any significant findings regarding stone burden (male: p = 0.054 and female: p = 0.078).
    CONCLUSIONS: The possibility of developing temporary sexual dysfunction should be taken into account for patients who are candidates for SWL treatment. As the patient\'s age and BMI increase, SWL-related sexual dysfunction becomes more severe.

    背景:这项研究的目的是对2019年冠状病毒病(COVID-19)封锁期间夫妻性生活的变化进行意大利远程信息处理调查分析。
    方法:一项多中心横断面研究是针对性活跃且关系稳定至少6个月的人群进行的。为了评估男性和女性的性功能障碍,我们使用国际勃起功能指数(IIEF-15)和女性性功能指数(FSFI),分别进行婚姻调整测验(第10-15项),评价婚姻质量和稳定性;评价焦虑症状的严重程度,我们使用汉密尔顿焦虑量表。隔离对夫妻关系的影响是通过内部提出的问题进行评估的。
    结果:我们包括2149名参与者。49%的参与者性生活有所改善,特别是那些同居的人;29%的人恶化了,而对于22%的参与者来说,它没有改变。回答说性生活恶化的女性没有性功能障碍,但他们有焦虑,紧张,恐惧,和失眠。相反,报告性生活恶化的男性有勃起功能障碍和性高潮障碍。在两种性别中,失业或聪明的工作,或有儿子是导致夫妻性生活恶化的危险因素。
    结论:本研究应鼓励评估COVID-19对夫妻性生活的长期影响。
    BACKGROUND: the aim of this study was to perform an Italian telematics survey analysis on the changes in couples\' sex lives during the coronavirus disease 2019 (COVID-19) lockdown.
    METHODS: a multicenter cross sectional study was conducted on people sexually active and in stable relationships for at least 6 months. To evaluate male and female sexual dysfunctions, we used the international index of erectile function (IIEF-15) and the female sexual function index (FSFI), respectively; marital quality and stability were evaluated by the marital adjustment test (items 10-15); to evaluate the severity of anxiety symptoms, we used the Hamilton Anxiety Rating Scale. The effects of the quarantine on couples\' relationships was assessed with questions created in-house.
    RESULTS: we included 2149 participants. The sex lives improved for 49% of participants, particularly those in cohabitation; for 29% it deteriorated, while for 22% of participants it did not change. Women who responded that their sex lives deteriorated had no sexual dysfunction, but they had anxiety, tension, fear, and insomnia. Contrarily, men who reported deteriorating sex lives had erectile dysfunctions and orgasmic disorders. In both genders, being unemployed or smart working, or having sons were risk factors for worsening the couples\' sex lives.
    CONCLUSIONS: this study should encourage evaluation of the long-term effects of COVID-19 on the sex lives of couples.

    The aim of this retrospective study was to evaluate the incidence of male sexual dysfunction after mid to low rectal cancer surgery and to identify factors associated with postoperative erectile and ejaculatory dysfunction.
    The subjects were 410 consecutive male patients who underwent surgery for mid to low rectal cancer from 2009 to 2015. Two questionnaires on sexual function were administered: the International Index of Erectile Function, and an original questionnaire on ejaculatory status. Erectile and ejaculatory dysfunction were examined before and 3, 6, 12 months after surgery. In patients without preoperative dysfunction, multivariate regression analyses were performed to identify factors associated with the incidence of erectile and ejaculatory dysfunction at 12 months after surgery.
    Of 410 patients, 234 (57%) gave complete responses to the questionnaires, of whom 108 (46%) and 155 (66%) had severe erectile dysfunction, while 115 (49%) and 168 (72%) had severe ejaculatory dysfunction before and 12 months after surgery, respectively. Of the patients who maintained sexual function preoperatively, the incidence of erectile and ejaculatory dysfunction at 12 months after surgery was 51% (64/126) and 49% (58/119), respectively. In multivariate analysis, age >60 years (P = 0.02), laparotomy (P = 0.002), and creation of a diverting ileostomy (P = 0.003) were independent factors associated with postoperative erectile dysfunction, while age >60 years (P = 0.005), laparotomy (P = 0.04), and lateral lymph node dissection (P = 0.001) were independent factors associated with postoperative ejaculatory dysfunction.
    Sexual dysfunction occurred in almost half of patients after rectal cancer surgery, and was independently associated with several factors, including laparotomy.
