Male Reproductive System Anatomy Overview

Male Reproductive System - Anatomy Overview

• Primary Organs

  • Testes:
    • Function: Produce sperm and testosterone.
    • Location: Scrotum, outside the body for temperature regulation.
  • Epididymis:
    • Function: Stores and matures sperm.
    • Structure: Coiled tube attached to the testes.

• Ducts and Passageways

  • Vas Deferens:
    • Function: Transports sperm from the epididymis to the ejaculatory duct.
    • Structure: Thick-walled, muscular tube.
  • Seminal Vesicles:
    • Function: Produce seminal fluid that nourishes and helps transport sperm.
  • Prostate Gland:
    • Function: Secretes a fluid that enhances sperm motility and viability.
  • Bulbourethral Glands (Cowper's Glands):
    • Function: Produce a pre-ejaculatory fluid that lubricates the urethra.

• External Structures

  • Scrotum:
    • Function: Houses the testes; regulates temperature.
  • Penis:
    • Main Components: Shaft, glans (tip), and erectile tissue.
    • Function: Delivers sperm to the female reproductive system and excretes urine.

• Urethra

  • Function: Conveys sperm (during ejaculation) and urine (during urination).
  • Path: Runs through the penis, connecting the reproductive and urinary systems.

• Supporting Structures

  • Surgical Structures:
    • Tunica Vaginalis: Layer covering the testes.
    • Dartos and Cremaster Muscles: Regulate temperature by contracting and relaxing the scrotum.

Understanding these components provides insight into the male reproductive system's function and interplay of structure and physiology.

Primary Organs

• Testes: Produce sperm and testosterone. Located in the scrotum, outside the body for temperature regulation.
• Epididymis: Stores and matures sperm. A coiled tube attached to the testes.

Ducts and Passageways

• Vas Deferens: Transports sperm from the epididymis to the ejaculatory duct. Thick-walled, muscular tube.
• Seminal Vesicles: Produce seminal fluid that nourishes and helps transport sperm.
• Prostate Gland: Secretes a fluid that enhances sperm motility and viability.
• Bulbourethral Glands (Cowper's Glands): Produce a pre-ejaculatory fluid that lubricates the urethra.

External Structures

• Scrotum: Houses the testes. Regulates temperature by contracting and relaxing.
• Penis: Delivers sperm to the female reproductive system and excretes urine. Composed of a shaft, glans (tip), and erectile tissue.
• Urethra: Conveys sperm (during ejaculation) and urine (during urination). Runs through the penis, connecting the reproductive and urinary systems.

Supporting Structures

• Tunica Vaginalis: Layer covering the testes.
• Dartos and Cremaster Muscles: Regulate temperature by contracting and relaxing the scrotum.
