Which of the following is incorrect regarding vasectomy?

Explanation

The correct answer is: b. No sperm occurs in epididymis Let's go through each option and explain why the correct answer is b: a. No sperm occurs in seminal fluid: This statement is correct. After a vasectomy, sperm is no longer present in the seminal fluid (ejaculate). The procedure involves cutting or sealing the vas deferens, which are the tubes that carry sperm from the testicles to the urethra. As a result, sperm cannot mix with the seminal fluid during ejaculation. b. No sperm occurs in epididymis: This statement is incorrect. The epididymis is a structure located on the posterior aspect of each testicle and serves as a storage and maturation site for sperm. A vasectomy does not affect the presence of sperm in the epididymis. It only prevents sperm from reaching the ejaculate by blocking the vas deferens. c. Vasa deferentia is cut and tied: This statement is correct. In a vasectomy, the vasa deferentia, which are the tubes that carry sperm from the testicles to the urethra, are cut, tied, or sealed to prevent the release of sperm during ejaculation. Summary: Vasectomy involves cutting or sealing the vasa deferentia, preventing sperm from being ejaculated in the seminal fluid. However, sperm remains in the epididymis, and this is the incorrect statement.
