Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

19.1K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Sympathetic Activation01:16

Sympathetic Activation

6.6K
The sympathetic division can influence tissues and organs by releasing norepinephrine at peripheral synapses and distributing epinephrine and norepinephrine through the bloodstream. In times of crisis or stress, sympathetic activation occurs, which is regulated by sympathetic centers in the hypothalamus. As a result, sympathetic activation prepares the body for physical exertion, rapid ATP production, and heightened alertness, allowing individuals to respond effectively to challenging or...

Disorders of the Autonomic Nervous System

1.4K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
Raynaud's disease, also known as Raynaud's...

Sex-linked Disorders01:43

Sex-linked Disorders

108.3K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

科学领域:

  • 神经科学是一个神经科学.
  • 泌尿器科 泌尿器科 泌尿器科 泌尿器科
  • 精神病学是一个精神病学.

背景情况:

  • 情境延迟射精 (SD-DE) 的特点是保持自慰功能,但持续性性交无射精.
  • 这种情况显著影响生活质量,并导致痛苦.
  • 底层的神经生理学,特别是自主机制,仍然不清楚.

研究的目的:

  • 为了研究SD-DE患者的同情性功能,使用阴茎同情性皮肤反应 (PSSR).
  • 评估SD-DE中交感功能障碍的临床相关性.

主要方法:

  • 纳入了67名SD-DE患者和65名正常对照 (NCs).
  • 分析了阴茎交感皮肤反应 (PSSR) 延迟和幅度,阴茎感觉值 (PST) 和临床特征 (包括自我评价焦虑量表,SAS).
  • 评估了交感神经系统的功能.

主要成果:

  • 与NCs (P<0.001) 相比,SD-DE患者的PSSR延迟时间 (交感性过活) 显着较短 (P<0.001).
  • 较短的PSSR延迟与焦虑评分负相关 (P<0.001),表明压力介导的同情性过度激活.
  • SD-DE患者有更高的PST,更高的自慰频率和更高的非典型自慰患病率,这表明了补偿性适应.

结论:

  • 交感功能障碍是SD-DE的核心特征 (DSM-5 302.74),PSSR作为一个客观生物标志物.
  • 阴道内射精的表型是DSM-5 302.74中的一个独特的临床实体,为向治疗提供信息.
  • 未来的研究应该结合多式联络神经成像来验证病态电路机制.
