Penis01:29

Penis

7.8K
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...

Muscles of the Pelvic Floor and Perineum01:26

Muscles of the Pelvic Floor and Perineum

1.9K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Accessory Glands of the Male Reproductive System01:16

Accessory Glands of the Male Reproductive System

1.9K
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

4.3K
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...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

365
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Accessory Ducts of the Male Reproductive System01:25

Accessory Ducts of the Male Reproductive System

1.6K
The male reproductive system is a complex network of organs and tissues that work together to produce and transport sperm. The epididymis, vasa deferens, ejaculatory ducts, and urethra are the accessory ducts involved in sperm maturation and transportation. These ducts play a critical role in the production 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....

Summary

Pilonidal sinuses, typically found in the buttocks, can rarely affect the penis, presenting as painful, itching lesions with fistulas and hair. Surgical debridement is the recommended treatment for this rare condition.

Area of Science:

  • Urology
  • Dermatology
  • Surgical Pathology

Background:

  • Pilonidal sinus disease commonly affects the sacrococcygeal region.
  • Penile involvement is exceptionally rare, necessitating consideration in differential diagnoses.

Observation:

  • A 43-year-old male presented with a painful, itching penile lesion.
  • Physical examination revealed multiple fistulas with protruding hairs and surrounding induration.

Findings:

  • The condition was diagnosed as a penile pilonidal sinus.
  • Surgical debridement was successfully performed by a urologist.

Implications:

  • Penile pilonidal sinus is a rare differential diagnosis for penile lesions, including balanoposthitis, epidermal cysts, and penile carcinoma.
  • Highlights the importance of considering rare diagnoses in atypical presentations.
