Question

The method of contraception that is hormone-based and prevents ovulation is :

• A. Oral Pills
• B. Copper-T
• C. Condom
• D. Lippes loop

Hint:

Oral pills contain progestogen and oestrogen, which stop the release of the ovum from the ovary.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Contraceptives may be barrier methods, intrauterine devices (IUDs), hormonal methods or surgical methods. The question asks for one that works through hormones and stops ovulation.

Step 2: Find the hormone-based method:
Oral pills contain small doses of progestogen alone or progestogen with oestrogen. They are taken daily for 21 days. These hormones block the release of the ovum from the ovary, so ovulation does not occur. They also make the cervical mucus thick, which hinders sperm entry.

Step 3: Why the others are wrong:
Copper-T is an IUD. Copper ions released from it reduce sperm motility and fertilising ability, and it has no role in ovulation. Condom is a barrier that stops sperm from meeting the ovum. Lippes loop is a non-medicated IUD, a plastic device in the uterus that does not work through hormones.

Final Answer:
Oral pills are hormone based and prevent ovulation. Option (A).
