迟发性睾丸功能减退的筛查、诊断、治疗和监测(二) 总被引:3,自引:2,他引:1
四、诊断
LOH的诊断包括三个方面内容:(1)症状评价;(2)血清睾酮测定;(3)试验性睾酮补充治疗的反应。三者是统一和相互相成的,单纯有症状或血清睾酮水平降低,对睾酮补充治疗无反应的患者不能诊断LOH,应该进一步检查可能引起症状的其它原因。 相似文献

迟发性睾丸功能减退筛查量表的研究与应用现状 总被引:2,自引:1,他引:1
随着迟发性睾丸功能减退(LOH)研究的深入,LOH筛查量表研究逐渐完善。常用筛查量表有AMS量表、ADAM问卷、MMAS问卷,量表的主要作用是筛查或者诊断LOH以及治疗效果的评估,目前研究主要集中在量表的应用、敏感性和特异性的验证、量表评价结果或者某些项目与血清激素水平之间的相关性、不同量表之间的比较等方面。本文综述筛查量表的研究、应用现状,并对其敏感性、特异性进行了总结。 相似文献

迟发性睾丸功能减退的筛查、诊断、治疗和监测 总被引:1,自引:0,他引:1
在19世纪40年代,Werner通过敏锐而深入的临床观察发现,男子在50岁以后出现体能下降、容易疲劳、记忆力减退、注意力不集中、烦躁不安、郁抑、潮热、阵汗和性功能减退等症状,命名为男子更年期综合征(male climacteric)。Bauer认为男子更年期综合征的命名是用词不当,上述症状是睾丸功能减退的表现。Heller等提出,只有尿促性腺激素水平增高的患者才能诊断男子更年期综合征。 相似文献

本文旨在研究土耳其爱琴海地区的老年男性下尿路症状(LUTSs)、勃起功能障碍(ED)和有症状的迟发性性腺功能减退症(SLOH)三者间的关系。符合以下标准的500名男性患者被纳入该研究:40周岁以上;过去6个月内有稳定的性关系;在六个泌尿外科诊所之一进行过就诊登记。每位患者均行血清PSA、睾酮水平及尿流率的检测,并填写国际前列腺症状评分和生活质量评分(IPSS-QoL)量表、国际勃起功能指数(IIEF)问卷和老年男性症状(AMS)量表。在所有的研究对象中,23.9%的患者有轻度LUTSs,53.3%有中度LUTSS,22.8%有重度LUTSS。每组间总睾酮水平无明显差异。除此之外,69.6%的病人患有ED,且ED的发生率与LUTS严重性呈正相关。71.2%的患者出现SLOH(AMS〉27),且IPSS评分越高,严重的性腺功能减退症状的发生率也越高。相关性分析显示以上三种问卷分数之间有显著关联。总之,LUTS严重性是ED和SLOH的非年龄依赖性危险因素,LUTS严重性和SLOH症状之间似乎有显著的相关性,但还需要从病因学和生物学角度进行深入阐明。 相似文献

In humans androgen decline is presented as a clinical picture which includes decreased sexual interest, diminished erectile capasity, delayed or absent orgasms and reduced sexual pleasure. Additionally, changes in mood, diminished well being, fatigue, depression and irritability are also associated with androgen insufficiency. The critical role of androgens on the development, growth, and maintanence of the penis has been widely accepted. Although, the exact effect of androgens on erectile physiology still remains undetermined, recent experimental studies have broaden our understanding about the relationship between androgens and erectile function. Preclinical studies showed that androgen deprivation leads to penile tissue atrophy and alterations in the nerve structures of the penis. Furthermore, androgen deprivation caused to accumulation of fat containing cells and decreased protein expression of endothelial and neuronal nitric oxide synthases (eNOS and nNOS), and phosphodiesterase type-5 (PDE-5), which play crucial role in normal erectile physiology. On the light of the recent literature, we aimed to present the direct effect of androgens on the structures, development and maintanence of penile tissue and erectile physiology as well. Furhermore, according to the clinical studies we conclude the aetiology, pathophysiology, prevalance, diagnosis and treatment options of hypogonadism in aging men. 相似文献

几种睾酮制剂用于治疗老年男性性腺功能减退。这些疗法在其便利性、灵活性、区域供应和费用等方面有区别,但有共同的药代动力学基础,同时缺乏长期安全性数据。简洁和成本较低的基于药代动力学的注册临床试验使得开发改善性的治疗迟发性性腺功能减退的新疗法的商业动机减少了。在前列腺、头发、皮肤受雄激素缺乏影响的患者中,选择性雄激素受体调节剂已被证明可以提供合成代谢的好处。(目前,选择性雄激素受体调节剂的临床进展集中在有限定身体功能的临床终点的急性肌肉萎缩和低体重)。在具有有益的药理、理想的药代动力学的选择性雄激素受体调节剂应用于治疗迟发性男性性腺功能低下症前,其在男性性腺功能低下治疗中关于临床缺陷的更清晰的监管是必须的。 相似文献

Testicular Findings, Endocrine Features and Therapeutic Responses of Men with Acquired Hypogonadotropic Hypogonadism 总被引:2,自引:0,他引:2

Background Men with acquired hypogonadotropic hypogonadism (AHH) who desire restoration of fertility are treated with exogenous gonadotropin. However, gonadotropin (Gn) therapy does not always restore testicular function. It is unknown whether the therapeutic responses to Gn therapy correlate with their testicular histological findings. Thus, we analyzed factors influencing testicular dysfunction and therapeutic responses in AHH.
Methods Of 21 men with AHH, 11 had no postmeiotic germ cells and were classified as the severe spermatogenic failure group. These were compared with the other 10 patients who had postmeiotic germ cells and comprised the mild spermatogenic failure group.
Results: Testicular volume and tubular diameter were significantly smaller, and the basement membrane and tunica propria were significantly thicker in the severe failure group. The gonadotropin basal level and response to exogenous gonadotropin-releasing hormone, and the testosterone response to exogenous human chorionic gonadotropin were significantly lower in the severe failure group of patients. Also, the recovery of spermatogenesis and testosterone secretory potentials was poor in the cases with a duration between diagnosis and treatment of 2 years or more.
Conclusion Longer periods without treatment may be responsible for irreversible testicular dysfunction in AHH. Gn therapy should be initiated very soon after the diagnosis of AHH if fertility is desired. 相似文献

Basal and TRH stimulated plasma prolactin levels were determined in 24 pubertal boys with hypogonadism (Primary: n = 10; secondary: n = 4; tertiary (hypothalamic): n = 10) and controls matched for pubertal stage (n = 12). The differentiation between secondary and tertiary hypogonadism was made with the help of a prolonged LRH test. The TRH test was performed by injecting 200 mcg i.v. in one bolus and taking plasma samples at 0, 15, 30, 60 and 90 minutes. No statistically significant differences were found between any of the groups. It is concluded that determination of basal or TRH stimulated prolactin does not contribute to clarify the etiology of hypogonadism or to determine the grade of damage or dysfunction in the hypogonadic testes. 相似文献

Study Type – Prognosis (retrospective cohort) Level of Evidence 2b What’s known on the subject? and What does the study add? Late onset hypogonadism is a syndrome combining low testosterone levels and clinical symptoms. But specific testosterone levels as well as clinical symptoms (e.g. sexual dysfunction) are poorly defined and still under debate. This study explores the association between testosterone levels and clinical symptoms with regard to co‐morbidities such as obesity, smoking and age. A main focus in this study is to investigate the influence of age on late onset hypogonadism, as many symptoms, which are correlated to low testosterone, might reflect just a normal process of aging. Finally the results show that only few symptoms (mainly psychosomatic symptoms) are associated with low testosterone and all other symptoms are significantly associated with age.
