Answer 1

Four methods of contraception used by humans—intrauterine devices, oral contraceptive methods, surgical methods and natural methods (coitus interruptus)

Two advantages of adopting such preventive methods:-

i. Helps in preventing unwanted pregnancies

ii. Reduces the chance of getting STDs such as AIDS

Answer 2

Four methods of contraception that can be used by humans are as follows:-

(i) Natural method: In this method, the sexual act is avoided from the 10th day to the 17th day of the menstrual cycle, as ovulation is expected during this period and the chances of fertilisation are very high.

(ii) Barrier method: In this method, the fertilisation of the ovum and the sperm is prevented with the help of a barrier such as a condom.

(iii) Oral contraceptive method: In this method, tablets or drugs are taken orally to prevent fertilisation.

(iv) Implants and surgical methods: Contraceptive devices, such as a loop and a Copper-T rod, are placed in the uterus to prevent pregnancy. However, they can cause side effects to the uterus. (these techniques is not meant for males)

Some surgical methods such as vasectomy (blocking of the vas deferens in the male body to prevent the transfer of sperms) and tubectomy (blocking of fallopian tubes in the female body to prevent the egg from reaching the uterus) can also be used to block the gamete transfer.

The following are the effects of contraception on the health and prosperity of a family:-

(i) It helps in preventing unwanted pregnancies.

(ii) It prevents the chances of frequent pregnancies, which, otherwise, affect the health of females.

(iii) It helps in family planning by controlling the number of children in a family.

(iv) It also reduces the chances of transmission of sexually transmitted diseases such as AIDS.

In this way, birth control methods play an important role in the health and prosperity of a family.
