Contraception means prevention of pregnancy and contraceptive methods work in a variety of ways. They may prevent the sperm from fertilising the ovum, prevent ovulation or change the endometrium so the fertilised ovum can’t implant.
Different people have different attitudes towards contraception. They may decide not to use contraception for cultural, religious or lifestyle reasons but most people want to plan when they have children and the number of children they would like to have.
How the different methods work:
stopping the release of eggs (oral contraceptive pills, hormone injection, vaginal ring)
stopping sperm getting into the male ejaculate (vasectomy)
stopping the egg and sperm meeting by:
using a barrier (condom)
thickening the mucus at the cervix to stop the sperm getting through
blocking the tubes between the ovary where the eggs are produced and the uterus (female sterilisation)
being toxic to the eggs and sperm (copper IUD)
making the lining of the womb too thin for the fertilised egg to embed
How are they used?
a pill taken by mouth
an injection or implant under the skin
an intrauterine device that is inserted into the uterus
a hormone vaginal ring or a diaphragm that the woman inserts into the vagina
a condom that covers the male penis or the inside of the vaginal walls
How good are they at preventing a pregnancy?
There are a number of safe and effective methods of contraception available in Australia and it is important to find the method that is best for you. Learning about each method may help you make your decision. Only you can decide what is best for you.
There is no method that is 100 per cent effective. The effectiveness of different methods can be measured by ‘perfect-use’ where rules of the method are rigorously followed, and (if applicable) the method is used at every act of intercourse. The failure rates in practice (typical use) are higher than perfect-use rates for a variety of reasons.
At Greenslopes Day Surgery Bisbane – we offer a variety of contraception options. The most popular contraception would be the IUD Mirena. Mirena is an intrauterine device that releases small amounts of the hormone levonorgestrel locally into your uterus. Made of soft, flexible plastic, Mirena is placed by our healthcare provider during an scheduled appointment.
Mirena offers contraception that’s over 99% effective; in fact, it is one of the most effective methods of reversible birth control
Mirena prevents pregnancy for up to 5 years.
You can try to become pregnant as soon as Mirena is removed. In fact, about 8 out of 10 women who want to become pregnant succeed in becoming pregnant within 1 year of having Mirena removed.
