Sexually Transmitted Infections01:26

Sexually Transmitted Infections

1.1K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

20.5K
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...

Development of the Sexual Organs in the Embryo and Fetus01:15

Development of the Sexual Organs in the Embryo and Fetus

3.7K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

Export of Mitochondrial and Chloroplast Genes02:19

Export of Mitochondrial and Chloroplast Genes

4.2K
A eukaryotic cell can have up to three different types of genetic systems: nuclear, mitochondrial, and chloroplast. During evolution, organelles have exported many genes to the nucleus; this transfer is still ongoing in some plant species. Approximately 18% of the Arabidopsis thaliana nuclear genome is thought to be derived from the chloroplast’s cyanobacterial ancestor, and around 75% of the yeast genome derived from the mitochondria’s bacterial ancestor. This export has occurred...

Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

30.7K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Attitudes01:54

Attitudes

33.2K
Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

Summary
This summary is machine-generated.

Sexual dysfunction is common in cervical dystonia (CD) and blepharospasm (BL), impacting quality of life. Depression, age, and single status were key predictors of sexual dysfunction in these patients.

Area of Science:

  • Neurology
  • Sexual Medicine

Background:

  • Sexual dysfunction is an underrecognized symptom in neurological disorders.
  • Limited data exists on sexual dysfunction prevalence in cervical dystonia (CD) and blepharospasm (BL).

Purpose of the Study:

  • To investigate the prevalence of sexual dysfunction in patients with CD and BL.
  • To identify factors associated with sexual dysfunction in these patient groups.

Main Methods:

  • A controlled study utilizing the Arizona Sexual Experience Scale was conducted.
  • 65 patients with CD and 54 patients with BL were assessed for sexual dysfunction.

Main Results:

  • Sexual dysfunction was significantly higher in CD patients (45%) compared to controls (24%) and frequent in BL patients (39%).
  • Disease duration or severity did not correlate with sexual dysfunction, but 23% of CD patients linked worsening sexuality to their condition.
  • Depression symptoms, age, and single personal status were the strongest predictors of sexual dysfunction.

Conclusions:

  • Sexual dysfunction is a frequent and burdensome non-motor symptom in CD and BL.
  • Clinicians should consider sexual dysfunction when evaluating adult-onset focal dystonia patients.
