It seems that you are referring to a figure or diagram associated with the male reproductive system. While I don’t have access to visual images within your materials (like the figure you’re referencing), I can describe the male reproductive system in detail, explain its components, and guide you on how different structures function. If you describe or specify a part of the diagram, I can assist with focused explanations!

Components of the Male Reproductive System

The male reproductive system consists of several organs that work together to produce, maintain, and transport sperm cells and seminal fluid, as well as discharge semen during reproduction. Here’s a breakdown of the major components:

External Organs

  1. Penis

    • The penis is the external reproductive organ through which sperm is delivered to the female reproductive system.
    • It has three main parts:
      1. Glans Penis: The sensitive expanded tip of the penis.
      2. Shaft: The elongated part of the penis.
      3. Prepuce (Foreskin): The skin covering the glans, which may be removed in circumcision.
    • The urethra runs through the penis, serving as a pathway for semen and urine.

  2. Scrotum

    • The scrotum is a pouch of skin that holds and protects the testicles.
    • It regulates the temperature of the testicles, maintaining an optimal environment for sperm production (about 2–3°C below body temperature).

Internal Organs

1. Testes (Testicles)

  • The testes are oval-shaped organs located inside the scrotum. They are the primary male reproductive organs.
  • Functions include:
    • Production of sperm cells (spermatogenesis).
    • Secretion of testosterone, the male sex hormone responsible for secondary sexual characteristics.

2. Epididymis

  • A coiled tube attached to each testis where sperm mature and become motile.
  • It serves as a storage area for sperm prior to ejaculation.

3. Vas Deferens (Ductus Deferens)

  • A muscular duct that transports sperm from the epididymis to the urethra during ejaculation.
  • It joins with the seminal vesicle to form the ejaculatory duct.

4. Seminal Vesicles

  • Glandular structures that produce a thick fluid rich in fructose, which provides energy for sperm.
  • This fluid makes up the majority of the seminal fluid, which combines with sperm to form semen.

5. Prostate Gland

  • The prostate gland contributes additional fluid to semen, including enzymes, zinc, and citric acid.
  • This fluid helps neutralize the acidic environment of the vagina, improving sperm survival.

6. Bulbourethral Glands (Cowper’s Glands)

  • These small glands secrete a clear, lubricating fluid that neutralizes residual acidity in the urethra and provides lubrication for sperm movement.

7. Urethra

  • The urethra serves as a common duct for urine and semen but performs these functions at different times.
  • Internal sphincters ensure that urine and semen do not mix during ejaculation.

Summary of the Path of Sperm:

The pathway sperm takes from production to ejaculation can be summarized as follows:

  1. Testes → Produces sperm.
  2. Epididymis → Maturation and storage of sperm.
  3. Vas Deferens → Transportation to the ejaculatory duct.
  4. Seminal Vesicles & Prostate Gland → Contribute to seminal fluid.
  5. Urethra (inside penis) → Discharge of semen during ejaculation.

Common Questions Students Ask About the Male Reproductive System

1. What is the difference between sperm and semen?

  • Sperm are the male gametes (reproductive cells).
  • Semen is the fluid that contains sperm along with secretions from the seminal vesicles, prostate gland, and Cowper’s glands.

2. What is the role of testosterone in the male reproductive system?

  • Testosterone is responsible for:
    • The development of male secondary sex characteristics (e.g., deep voice, facial hair).
    • Stimulating sperm production.
    • Maintaining libido and muscle mass.

3. Why is the scrotum located outside the body?

  • Sperm production requires a temperature slightly cooler than body temperature, which is why the scrotum holds the testes outside the body for better heat regulation.

If there are any specific parts of the figure you’re looking at or a particular component you’d like clarification on, feel free to ask! I can also provide additional detailed insights about any processes, like spermatogenesis or the hormonal regulation of the reproductive system.
