Question

If the vas deferens of a man is surgically disconnected

• A. Sperms in the semen will be without nuclei.
• B. Semen will be without sperms.
• C. Spermatogenesis will not occur.
• D. Sperms in the semen will be non-motile.

Answer 1

Answer: (B)

Semen will be without sperms.

Vas deferens is a muscular tube that carries sperms from epididymis into the abdominal cavity to the ejaculatory duct. It is wider than the epididymis and therefore, uses its internal space to store mature sperms. The smooth muscles of the wall of vas deferens are used to move sperms into the ejaculatory duct through peristalsis.
Now, if vas deferens is removed, then there will be no sperms in the semen.
Hence, the correct answer is B.
