Question

What would happen if vasa deferentia of man are cut?

• A. Sperm are non-nucleate
• B. Spermatogenesis does not occur
• C. Semen is without sperms
• D. Sperms are non-motile

Answer 1

The correct option is C Semen is without sperms

As vas deferentia of man is cut which means that the passage of sperm will be blocked. But as testis are perfectly normal so the process of spermatogenesis will continue normally which means that sperms will be perfectly normal that is they will be nucleated as well as motile. Just semen will be without sperm because semen is formed by prostate bulbourethral and seminal vesicle so semen will be formed but it will be without sperm.

So, the correct answer is 'Semen is without sperms'.
