Summary
Erectile dysfunction (ED) treatments in Japan should be fast-acting. Most couples rarely have intercourse more than once per opportunity and cannot predict sexual activity 30 minutes in advance.
Area of Science:
- Urology
- Andrology
- Sexual Medicine
Background:
- The introduction of phosphodiesterase type-5 (PDE5) inhibitors like sildenafil and vardenafil has transformed erectile dysfunction (ED) management in Japan.
- Limited research exists on the actual sexual activity patterns within married couples since the market release of these ED medications.
- Understanding couples' sexual behavior is crucial for developing effective ED treatments.
Purpose of the Study:
- To investigate the frequency, periodicity, and predictability of sexual intercourse in married couples in Japan.
- To gather insights into sexual activity patterns relevant to the treatment of ED.
Main Methods:
- A questionnaire survey was administered to 300 married couples.
- Participants reported having had sexual intercourse at least once within the preceding three months.
- Data collected included frequency, timing, and predictability of sexual encounters.
Main Results:
- A low frequency of intercourse was observed, with few couples engaging in it more than once per opportunity.
- The majority of sexual intercourse occurred during nighttime hours.
- Over 80% of couples reported an inability to foresee sexual intercourse 30 minutes in advance.
Conclusions:
- Current ED treatments should prioritize rapid onset of action to facilitate spontaneous sexual activity.
- Medications should enable couples to engage in intercourse comfortably and without significant planning.
- The findings suggest a need for ED therapies that align with unpredictable sexual opportunities.

1.2K
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...

01:21G-protein Coupled Receptors
132.2K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

17.3K
The normal, a continuous distribution, is the most important of all the distributions. Its graph is a bell-shaped symmetrical curve, which is observed in almost all disciplines. Some of these include psychology, business, economics, the sciences, nursing, and, of course, mathematics. Some instructors may use the normal distribution to help determine students’ grades. Most IQ scores are normally distributed. Often real-estate prices fit a normal distribution. The normal distribution is...

01:19Normal Stress
1.5K
Normal stress is a type of stress that occurs when forces act perpendicular, or normal, to a material's cross-sectional area. This stress often arises in structures when subjected to axial loading, which is the application of force along the axis of an object. A practical example of this can be found in bridge truss members.
When a rod is under axial loading, the internal forces and corresponding stress are normal to the plane of the section, so it is termed normal stress. It's important to...

01:17Male Sexual Response: Erection & Ejaculation
21.7K
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...

01:20Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
1.7K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
