Question

In human beings, if the spermatozoa are not ejaculated, then .........

• A. they are inactivated within the seminal vesicles.
• B. they are permanently stored in cauda epididymis.
• C. they are permanently stored in caput epididymis.
• D. they are re-absorbed in the vas deferens.

Hint:

The re-absorption of sperm is a natural process in the male reproductive system when sperm is not ejaculated.

Answer 1

The Correct Option is D

Step 1: Understanding sperm storage.
In humans, sperm that is not ejaculated is re-absorbed by the body in the vas deferens. The sperm is not stored permanently in the epididymis, as it is either used or re-absorbed.
Step 2: Analyzing the options.
(A) they are inactivated within the seminal vesicles: Incorrect, sperm is not stored or inactivated in the seminal vesicles.
(B) they are permanently stored in cauda epididymis: Incorrect, sperm is not stored permanently in the epididymis.
(C) they are permanently stored in caput epididymis: Incorrect, sperm is not stored permanently in the caput epididymis.
(D) they are re-absorbed in the vas deferens: Correct, when not ejaculated, sperm is re-absorbed by the body in the vas deferens.
Step 3: Conclusion.
The correct answer is (D) they are re-absorbed in the vas deferens.
