Question

Assertion (A) : Male contraceptive ‘Nirodh’ works on the principle of avoiding chances of ovum and sperm meeting.
Reason (R) : It is made of thin rubber/latex sheath and is used to cover the penis before coitus.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

Understand how barrier methods of contraception work. They physically prevent the sperm from reaching the ovum, thus fulfilling the principle of avoiding the meeting of gametes.

Answer 1

The Correct Option is A

Assertion (A) states that the male contraceptive 'Nirodh' works on the principle of avoiding the chances of ovum and sperm meeting. This is true. Contraceptive methods aim to prevent fertilization, which occurs when the sperm and ovum fuse.
Reason (R) states that 'Nirodh' is made of a thin rubber/latex sheath and is used to cover the penis before coitus. This is also true. 'Nirodh' is a condom, which is a barrier method of contraception made of latex or rubber that covers the penis during sexual intercourse. The reason (R) directly explains how 'Nirodh' achieves the principle stated in the assertion (A). By covering the penis, the condom acts as a physical barrier, preventing the release of semen containing sperm into the female reproductive tract. This effectively avoids the meeting of sperm and ovum, thus preventing fertilization. Therefore, Reason (R) is the correct explanation of Assertion (A).
