The Answer is -

●▬▬▬▬▬▬๑۩۩๑▬▬▬▬▬▬▬●

(i) Barrier Method: In this method, physical devices such as condoms, diaphragm and cervical caps
are used. These devices prevent the entry of sperm in the female genital tract during copulation,
thus acting ‘ as a barrier between them.

(ii) Hormonal Imbalance Method: In
this method, specific drugs are used by females, which are of two types: oral pills and vaginal pills.
Oral pills contain hormones which stop the ovaries from releasing ovum into the fallopian tube. These
pills are also called oral contraceptives (OCs) which act by changing the hormonal balance of the
body so that eggs are not released and fertilisation cannot occur. The use of Intrauterine
Contraceptive Devices (IUCDs) prevents implantation in the uterus. This device is copper-T placed
safely inside the uterus by a doctor or nurse.

(iii) Surgical Method: In this method, a small portion of vas deferens in male and the fallopian tube
in ‘ female is surgically removed or tied. It is called vasectomy in males and tubectomy in females. In
this case, if the vas deferens in male is blocked, sperm transfer will be prevented and if the fallopian
tube in the female is blocked, the egg will not be able to reach the uterus, thus fertilisation will not take place.
