Contraceptives are birth control methods and thus, couples can avoid unwanted pregnancies. This, in turn, will help to stabilize the increasing population, especially in a country like India. There are various methods of contraception and these are natural methods, barrier methods, intrauterine methods, oral pills, injections, implants etc. Barrier methods provide contraception by blocking the passage of sperms. These are self inserted—examples: condoms, femidoms, cervical caps, diaphragms etc.
