How effective is contraception?
All the methods of contraception listed below are effective and all are available in our clinic. However, no method is absolutely 100% reliable. The reliability for each method is given in percentages. For example, the contraceptive injection is more than 99% effective. This means that less than 1 woman in 100 will become pregnant each year using this method of contraception. The effectiveness of some methods depend on how you use them. You have to use them properly, or they may lose their effect. For example, the ‘pill’ is more than 99% effective if taken correctly. If it is not (for example, if you miss a pill, etc) then it becomes less effective. Other ‘user dependent’ methods are barrier methods, the progestogen only pill, and natural family planning. Some methods are not so ‘user dependent’ and need to be renewed only infrequently or never. These methods are: the contraceptive injection, implant, intrauterine devices, and sterilisation.
When no contraception is used, more than 80 in 100 sexually active women become pregnant within 1 year.
What are the different methods of contraception available at the D2 Medical?
Choosing a method of contraception involves a balance between.
Often just called ‘the pill’. It is more than 99% effective if used properly. Contains oestrogen and progestogen. Works mainly by stopping ovulation. It is very popular. Different brands suit different people.
Progestogen only pill (POP)
Used to be called the ‘mini-pill’. Contains just a progestogen hormone. More than 99% effective if used properly. Is commonly taken if the combined pill is not suitable. For example: breast-feeding women, smokers over the age of 35, and some women with migraine. Works mainly by causing a plug of mucus in the cervix that blocks sperm, and by thinning the lining of the uterus. May also stop ovulation.
These include male condoms, female condom, diaphragms, and caps. Prevents sperm entering the uterus. Male condoms are about 98% effective if used properly. Other barrier methods are slightly less effective than this.
Contraceptive injections (eg Depoprovera) at the D2 medical
Contains a progestogen hormone which slowly releases into the body. More than 99% effective. Works by preventing ovulation and also has similar actions as the POP. An injection is needed every 8-12 weeks.
Contraceptive implants (eg Implanon) available in the D2 Medical
An implant is a small device placed under the skin. Contains a progestogen hormone which slowly releases into the body. Is more than 99% effective. Works in a similar way to the contraceptive injection. Involves a small minor operation using local anaesthetic. Each one lasts 3 years.
Intrauterine device (IUD) available in the D2 Medical,
A plastic and copper device is put into the uterus. Lasts 5 or more years. It works mainly by stopping the egg and sperm from meeting. It may also prevent the fertilised egg from attaching to the lining of the uterus. The copper also has a spermicidal effect (kills sperm).
Hormone releasing intrauterine device (eg Mirena) in the D2 Medical
Otherwise called the intrauterine system (IUS). A plastic device that contains a progestogen hormone is put into the uterus. The progestogen is releasedata slow but constant rate. More than 99% effective. Works in a similar way to the POP. Is also used to treat heavy periods (menorrhagia).
This involves fertility awareness. Effective if done correctly. Requires commitment and regular checking of fertility indicators such as body temperature and cervical secretions.
Involves an operation. Is more than 99% effective. Vasectomy (male sterilisation) stops sperm travelling from the testes. Female sterilisation prevents the egg from travelling along the Fallopian tubes to meet a sperm. Vasectomy is easier and more effective than female sterilisation. Popular when family is complete.
Can be used if you had sex without using contraception. Also, if you had sex but there was a mistake with contraception. For example, a split condom or if you missed taking your usual contraceptive pills.
