Penis

50.8K
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Male Sexual Response: Erection & Ejaculation

31.3K
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...

Disorders of the Male Reproductive System

5.2K
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Area of Science:

  • Optics and Photonics
  • Display Technology
  • Materials Science

Background:

  • Three-dimensional (3D) displays offer immersive visuals crucial for interactive media.
  • 2D-3D switchable displays provide the flexibility to alternate between high-resolution 2D and immersive 3D modes.
  • Existing technologies often face limitations in resolution, field of view, or form factor.

Purpose of the Study:

  • To propose and demonstrate a full-color 2D-3D switchable light-field display.
  • To utilize a metasurface lenticular lens (MLL) as the core switching mechanism.
  • To achieve a wide field of view and an ultrathin profile for practical display applications.

Main Methods:

  • Designed a metasurface lenticular lens (MLL) that switches focal behavior based on incident light polarization.
  • Engineered the MLL with a high numerical aperture for an expanded field of view.
  • Fabricated a large-area MLL (25 cm²) and integrated it with an organic light-emitting diode (OLED) display panel.

Main Results:

  • The MLL successfully enabled 2D-3D mode transition by altering its focal properties.
  • Achieved a wide field of view of 100° with an ultrathin display profile of 1.2 mm.
  • Demonstrated clear 2D and 3D image display and active switching functionality via applied voltage.

Conclusions:

  • The developed MLL-based display offers a promising solution for next-generation display technologies.
  • The approach demonstrates scalability for wide-area display applications.
  • This technology has potential applications in consumer electronics and commercial sectors requiring advanced visual interfaces.
