Male Reproductive System: Organs, Ducts and Glands
The male reproductive system is the set of primary and accessory reproductive organs that produce sperm, form semen and transfer male gametes into the female reproductive tract.
In one line: Testis makes, epididymis matures, vas deferens carries, glands add fluid, urethra releases.
Concept Practice Coming SoonUnderstand it
- The testes are the primary sex organs and are located in the scrotum, which helps maintain a temperature lower than body temperature for sperm formation.
- Each testis contains seminiferous tubules where spermatogenesis occurs.
- Sertoli cells nourish developing germ cells, while Leydig cells produce androgens such as testosterone.
- Sperm pass through rete testis, vasa efferentia, epididymis, vas deferens, ejaculatory duct and urethra.
- Accessory glands, including seminal vesicles, prostate and bulbourethral glands, add secretions that support sperm movement and viability.
- In exams, organ location, duct sequence and gland functions are commonly tested.
Example
Rule to remember
Key biological rule: structure supports function.
Testes produce sperm and testosterone; ducts transport and store sperm; glands add seminal plasma; external genitalia transfer semen.
See it worked out
Follow the example line by line, then use the same method on new questions.
Worked example
If asked to trace the path of sperm from formation to release, write: seminiferous tubules → rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct → urethra.
Method you can reuse
- 1To answer a pathway or structure-function question, first identify the testes as the primary organs and state that sperm form in the seminiferous tubules, while Leydig cells secrete testosterone.
- 2Next trace the sperm route in exact order: seminiferous tubules → rete testis → vasa efferentia → epididymis, where sperm mature and are stored → vas deferens → ejaculatory duct → urethra.
- 3Then add that seminal vesicles, prostate gland and bulbourethral glands contribute seminal plasma before semen is released through the urethra.
- 4Students usually lose marks by writing epididymis as the site of sperm production, skipping rete testis or vasa efferentia, or listing accessory glands without explaining that their secretions support sperm transport and viability.
Visual tip
Important labels are testis, scrotum, seminiferous tubules, epididymis, vas deferens, ejaculatory duct, urethra, seminal vesicle, prostate gland, bulbourethral gland and penis. Notice the duct pathway from testis to urethra.
Check yourself
Answer the question in your head before opening the answer.
Try it yourself
Why are the testes located in the scrotum instead of remaining fully inside the abdominal cavity?
Think first, then show answerHide answer
Common wrong answer
Testis → vas deferens → urethra only.
Why it loses marks: This misses epididymis and other ducts needed for a complete pathway.
Don't mix this up
Exam tip
Write it in the exam
Each point is worth about one mark. Write point 1 for a 1-mark question and keep adding points as the marks go up.
