What is contraception? Contraception refers to the deliberate use of various devices, drugs, agents, surgical methods or techniques to prevent unwanted pregnancy as a result of coitus (sexual intercourse), while ideally not interfering with libido, sexual drive or gratification.

Any two methods of contraception:
- Barrier methods: Devices such as condoms (for males and females), diaphragms, cervical caps and vaults physically prevent sperm from reaching the cervix/ovum, thus preventing fertilisation. They also help prevent sexually transmitted infections (STIs).
- Oral contraceptive pills: Hormonal pills containing a combination of synthetic estrogen and progestogen (or progestogen alone) are taken daily by the female; they primarily inhibit ovulation and also alter the cervical mucus to prevent sperm entry, thereby preventing pregnancy. (Other valid methods include IUDs like Copper-T, surgical methods such as vasectomy/tubectomy, and natural methods such as the rhythm method.)
