Identify the six required male reproductive structures
Original side-view model: six numbered reproductive parts; the bladder is a separate orientation landmark. Read the key for the function of every part.

Before you begin
- Recall cell nuclei, gametes, diffusion, respiration and the difference between a cell and an organ.
Work on paper. Try each question before revealing help, and explain why your method works.

Where are sperm produced?
What you will learn
- Locate the six structures by their connections
- Match producing supporting and transport functions
Original teaching model.
| Feature | Meaning |
|---|---|
| 1 · Testis | Produces sperm; secretes testosterone |
| 2 · Scrotum | Holds testes; suitable temperature |
| 3 · Sperm duct | Carries sperm away from testis |
| 4 · Prostate gland | Adds fluid to semen |
| 5 · Urethra | Carries semen to the exterior |
| 6 · Penis | Delivers semen into vagina |
Locate the six structures by their connections
The male-system diagram is an original side-view cutaway, not an intact transparent body. Start with the testes inside the scrotum, then follow a sperm duct upward and toward the urethra. The prostate gland surrounds the upper urethral region below the bladder. The urethra continues through the penis to the exterior; a label identifies the tube, not the whole surrounding organ.
Testes produce sperm and also secrete testosterone, a sex hormone. The scrotum holds the testes outside the main body cavity and helps maintain a suitable temperature for sperm production. Sperm ducts carry sperm away from the testes. The prostate adds fluid to semen, helping form the medium carrying sperm. Sperm are cells; semen is fluid containing sperm and gland secretions, not a synonym for the testes.
Match producing supporting and transport functions
The urethra carries semen through the penis to the outside during ejaculation. It also carries urine at different times. The penis delivers semen into the vagina during sexual intercourse. The bladder appears only to orient this cutaway: it stores urine and is not one of the six required reproductive structures. Do not relabel a sperm duct as a ureter merely because both are narrow tubes.
Identify a part by the endpoint of its label and its biological connection, not its colour or position on your screen. Diagrams can be rotated or simplified. A tube leaving a testis belongs to the sperm route; a urine tube from a kidney belongs to the urinary route. A clear answer names the requested structure and supplies its own function rather than listing every organ.
Pause and explain
Which connection identifies a sperm duct?
Worked example
A label ends on the tube running through the penis. Identify it and state its role in reproduction.
Show the worked solution
- Distinguish the tube from the surrounding organ.
- Follow the tube to the exterior.
Answer Urethra: carries semen through the penis to the exterior.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Name model labels 1, 2 and 3 and give one function each.
Give me a hint
Use the numbered key, then connect the first three parts.
Compare my reasoning
- Locate the testis within its supporting sac.
- Trace the tube leading away from the testis.
1 testis: produces sperm; 2 scrotum: holds testes and helps maintain suitable temperature; 3 sperm duct: transports sperm away from the testis.
Look for these in your work
- Name all three structures
- Give their different functions
Name model labels 4, 5 and 6 and give their reproductive functions.
Give me a hint
Separate gland, tube and surrounding organ.
Compare my reasoning
- Find the gland below the bladder.
- Trace the urethra through the penis.
4 prostate gland: adds fluid to semen; 5 urethra: carries semen to the exterior; 6 penis: delivers semen into the vagina.
Look for these in your work
- Distinguish gland and tube
- Include the penis function
A rotated diagram shows a bladder and a tube from a testis. A learner calls both sperm-producing organs. Correct the explanation.
Give me a hint
Rotation does not alter organ functions.
Compare my reasoning
- Identify production at the testis.
- Separate urine storage from sperm transport.
Testes produce sperm. The bladder stores urine, while the tube from the testis is a sperm duct transporting sperm; neither is a sperm-producing organ.
Look for these in your work
- Use source and connection
- Correct both errors
Common mistakes
- The bladder does not produce sperm.
- The urethra is a tube within the penis, not another name for the penis.
What can you explain now?
Which connection identifies a sperm duct?
Compare with the explanation
A tube carrying sperm away from a testis
Its source and transport role distinguish it from urinary tubes.

Make it stick
Explain locate the six structures by their connections and match producing supporting and transport functions. Use the diagram key and check your reasoning before opening the solutions.
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
