Penis01:29

Penis

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...
Accessory Glands of the Male Reproductive System01:16

Accessory Glands of the Male Reproductive System

The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...
Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

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...
Aneurysm III: Interprofessional Care01:26

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Summary
This summary is machine-generated.

Penile prosthesis implantation offers a solution for erectile dysfunction. New cylinders can improve erection length by expanding girth and length, addressing patient concerns about reduced size after surgery.

Area of Science:

  • Urology
  • Andrology
  • Medical Devices

Background:

  • Penile prosthesis implantation is a treatment for erectile dysfunction when other methods fail.
  • Three-piece inflatable prostheses aim for natural flaccidity and erection but often result in shorter erections.
  • Loss of penile length can occur due to prosthesis implantation, especially with standard girth-expanding cylinders.

Purpose of the Study:

  • To discuss the limitations of current penile prostheses regarding erection length and glans tumescence.
  • To explore the use of girth- and length-expanding cylinders to mitigate penile length loss.
  • To review penile lengthening procedures combined with prosthesis implantation for abnormal corpora cavernosa.

Main Methods:

  • Review of existing literature on penile prosthesis design and outcomes.
  • Analysis of factors contributing to reduced erection length post-implantation.
  • Discussion of surgical techniques for penile lengthening in conjunction with prosthesis insertion.

Main Results:

  • Standard penile prosthesis cylinders expand girth but not length, leading to patient-reported shorter erections.
  • Girth- and length-expanding cylinders show potential to reduce or eliminate penile length loss.
  • Combined penile lengthening and prosthesis implantation for abnormal corpora have limited documented experience.

Conclusions:

  • Advancements in penile prosthesis cylinder technology can improve patient satisfaction by addressing erection length.
  • Penile lengthening procedures may be an option for select patients with abnormal corpora, but require further investigation.
  • Optimizing penile prosthesis design and surgical techniques is crucial for restoring function and patient-reported outcomes.
