The correct sequence of organs in the male reproductive system for the transport of sperm is:
- Testis ➔ vas deferens ➔ urethra
Explanation:
- Sperm is produced in the testes.
- From the testes, sperm travels through the vas deferens.
- The vas deferens transports sperm to the urethra.
- The urethra serves as the final pathway for sperm to exit the body during ejaculation.
Therefore, option A: Testis ➔ vas deferens ➔ urethra is the correct sequence for the transport of sperm in the male reproductive system.

The Male Reproductive System: Overview
The male reproductive system is designed specifically for the production, maturation, and transport of sperm. Understanding the correct pathway is crucial for grasping male reproductive physiology.
Correct Sequence of Organs
The correct order for the transport of sperm is:
- Testis:
- Sperm production occurs in the seminiferous tubules of the testis.
- The testis also produces testosterone, which is vital for sperm development and male characteristics.
- Vas Deferens:
- After maturation, sperm move from the testis to the epididymis, where they are stored and further matured.
- From the epididymis, sperm travel through the vas deferens during ejaculation. This muscular tube contracts to propel sperm forward.
- Urethra:
- The vas deferens joins with the seminal vesicle to form the ejaculatory duct, which then opens into the urethra.
- The urethra serves as the final conduit, transporting sperm out of the body during ejaculation.
Why Other Options are Incorrect
- Option B (Testis → Ureter → Urethra):
- The ureter is not involved in the reproductive system. It carries urine from the kidneys to the bladder.
- Option C (Testis → Urethra → Ureter):
- This sequence is incorrect as sperm do not travel through the urethra before reaching the vas deferens.
- Option D (Testis → Vas Deferens → Ureter):
- Again, the ureter is irrelevant in sperm transport; it deals exclusively with urine.
Conclusion
Thus, the correct sequence for sperm transport is indeed Testis → Vas Deferens → Urethra, making option 'A' the right choice. Understanding this pathway is essential for comprehending male reproductive health and function.
