Condom is a rubber sheath which prevents pregnancy by acting as a barrier, preventing semen from entering the vagina.
Tubectomy is a surgical process that blocks the fallopian tubes, thereby preventing the egg released by the ovary to meet sperm.
The copper intrauterine device (IUD) is a small 'T-shaped' plastic and copper device which constantly releases a small amount of copper into the uterus (womb) and thus prevents implantation.
Hormonal methods of birth control prevent eggs from being released from the ovaries, thicken cervical mucus to prevent sperm from entering the uterus, and makes lining of the uterus thin to prevent implantation.
