Different contraceptives suit different people so it’s hard to say what ‘top’ contraceptives will be for you. Many contraceptives are over 99% effective when used properly, although some can be less effective because people don’t always use them properly, like the pill. Below are a list of the most effective contraceptives when you take into account people using some wrongly: Male sterilisation, permanent but effective if the procedure is successful. Female sterilisation, just like male sterilisation it’s very effective but permanent. Intrauterine device, often called ‘the coil’ this contraceptive is very effective when inserted correctly. Intrauterine system, similar to the coil and just as effective. Contraceptive implant, inserted under the skin and effective and reliable.
