Which of the following is incorrect regarding vasectomy ?
- No sperm occurs in epididymis
- No sperm occurs in seminal fluid
- Irreversible sterility
- Vasa deferentia is cut and tied
Answer
(1) No sperm occurs in epididymis
Solution
As per NCERT, in vasectomy a small part of the vas deferens is removed or tied up through a small incision on the scrotum.
⇒ Sperms are still produced in the testes and stored in the epididymis, but they cannot pass beyond the cut vasa deferentia.
∴ No sperm occurs in the seminal fluid (statement (2) is correct) and the vasa deferentia are cut and tied (statement (4) is correct).
∵ NCERT states that the reversibility of sterilisation methods is very poor, vasectomy is taken as an irreversible (permanent) method (statement (3) is correct).
⇒ The statement "No sperm occurs in epididymis" is incorrect.
Answer: (1)
