The methods of contraception are:
(i) Barrier method or mechanical method (Condom/Diaphragm): Prevents the meeting of sperms and ova.
(ii) Chemical method (Oral pills): Changes the hormonal balance of the female partner so that the eggs are not released.
(iii) Surgical method: The vas deferens in males is blocked (vasectomy) or the fallopian tube (oviduct) in females (tubectomy) is blocked to prevent the transfer of sperms or egg and hence no fertilisation takes place.
