Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion (A) : Vasectomy and tubectomy are highly effective contraceptive methods.

Reason  (R) : The reversibility of these methods is very poor.

In light of the above statements, choose the correct answer from the options given below.

Both Assertion (A) and Reason (R) are true, but (R) does not explain (A).

Assertion (A) is true. Vasectomy and tubectomy are indeed highly effective contraceptive methods. Vasectomy involves cutting or blocking the vas deferens, which prevents sperm from reaching the semen, while tubectomy involves cutting or blocking the fallopian tubes, which prevents eggs from reaching the uterus. Both procedures are considered highly effective in preventing pregnancy as they block the gamete transport.

Reason (R) is true. The reversibility of vasectomy and tubectomy procedures is generally poor. While some attempts can be made to reverse these procedures through surgical techniques like vasovasostomy (vasectomy reversal) or tubal ligation reversal, success rates vary, and the chances of achieving pregnancy after reversal may be lower. Therefore, they are often considered as permanent or long-term contraceptive methods.
