Given below are four methods (A-D) and their modes of action (i) – (iv) in achieving contraception. Select their correct matching from the four options which follow.

Detailed Solution: Question 1

a) Most birth control pills are "combination pills" containing a mix of the hormones estrogen and progesterone to prevent ovulation.

b) A condom acts as a physical barrier that prevents sperm from entering the uterus and reaching an egg.

c) The testes still make sperm, but the sperm die and are absorbed by the body. A man who has had a vasectomy still makes semen and is able to ejaculate. But the semen doesn't contain sperm.

d) The copper IUD works by stopping the sperm and egg meeting and changing the lining of the uterus/womb. This makes it difficult for a fertilised egg to stick to the lining to start a pregnancy. When it is first inserted (put in) it starts working straight away to prevent pregnancy.

Assertion (A): Women are at the peak of conception on the 14th day of ovulation.
Reason (R): Vasectomy is a method normally employed to avoid conception in females.

Diaphragms are contraceptive devices used by females. Choose the correct option from the statements given below:
(i) They are introduced into the uterus.
(ii) They are placed to cover the cervical region.
(iii) They act as physical barriers for sperm entry.
(iv) They act as spermicidal agents.​

Statement I: Oral contraceptive pills are a safeguard against AIDS and sexual diseases besides checking pregnancy.
Statement II: Copper-T is a physical barrier preventing the body fluid of two partners to come in contact.

Detailed Solution: Question 5

To analyze the statements provided, we will evaluate each one separately.

Step 1: Evaluate Statement I
Statement I: Oral Contraceptive pills are a safeguard against AIDS and sexual diseases besides checking pregnancy.

- Oral contraceptive pills (OCPs) are designed to prevent pregnancy by inhibiting ovulation and altering the uterine lining.
- They do not provide protection against sexually transmitted infections (STIs) or HIV/AIDS.
- Therefore, this statement is incorrect.

Step 2: Evaluate Statement II
Statement II: Copper-T is a physical barrier preventing the body fluid of two partners to come in contact.

- Copper-T is an intrauterine device (IUD) that is used for contraception.
- It works by preventing fertilization and does not act as a physical barrier to prevent body fluids from coming into contact, as it is placed inside the uterus.
- Physical barriers that prevent body fluids from mixing include condoms and diaphragms, not Copper-T.
- Therefore, this statement is also incorrect.

Conclusion
Both statements I and II are incorrect.
