Answer»

Solution :Three methods of contraception :
(i) Mechanical Barrier - Condoms on penis or vagina is a COVERING wom so as to create a barrier such that sperms do not reach the egg.
(ii) Oral Contraceptive Pills - They change the hormonal balance of the body so that eggs are not released and FERTILISATION does not take place.
(iii) Intra-Uterine Device - Devices like copper-T or LOOP are placed in the uterus which change the pH of uterus and hence sperms cannot survive, thereby preventing PREGNANCY.
(iv) Surgical METHOD - Blocking vas deferens in males and fallopian tube in females, would allow respective gametes to be released and hence act as contraceptive.
