What is contraception?
Contraception means different ways to prevent pregnancy. It’s sometimes called birth control.
Types of contraception
No form of contraception is 100% effective. Every method has its advantages and disadvantages. There are many things to consider when choosing a contraception method. For example:
- how well it works
- cost
- potential side effects
- how easy it is to use
- your stage of life.
Here are the most effective methods of contraception.
LARCs are highly effective methods of contraception. The other advantage is that you don’t have to think about contraception every day or every time you have sex.
Hormonal implant
Hormonal implants are over 99% effective. A doctor or nurse inserts a small implant under the skin of your upper arm. The implant releases the progestogen hormone, which stops ovulation. The implant lasts for 3 years.
Watch a video about implants on the Sexual Health Victoria website.
Hormonal injection
Hormonal injections are over 96% effective. A doctor or nurse gives you an injection of the progestogen hormone every 12 weeks, which stops ovulation.
Intrauterine device (IUD)
IUDs are over 99% effective. Hormonal IUDs are slightly more effective than copper ones. A doctor or nurse inserts the IUD (a small t-shaped device) into your uterus (womb) through your vagina, which stops sperm from reaching the egg.
Hormonal IUDs last for 5 years or longer. Copper IUDs last for 5 to 10 years.
Some IUDs may be an effective medical option for treating heavy periods.
The Pill is over 93% effective and up to 99% effective if taken correctly. You need to take a pill every day to prevent pregnancy. The Pill has oestrogen and progesterone hormones that stop egg release. You can also get a progesterone-only pill (mini pill). The mini pill is less effective because it must be taken at the same time every day to work.
Vaginal rings are over 93% effective. A vaginal ring has the same hormones that are in the Pill. You place a new ring high up in your vagina every month and leave it there for 3 weeks to prevent pregnancy.
Barrier methods of contraception work by stopping sperm from reaching an egg. These include:
- external condoms – worn over an erect penis (over 88% effective)
- internal condoms – a sheath that fits loosely into the vagina (over 79% effective)
- diaphragm – a soft silicone cap that is put into in the vagina before sex (over 82% effective).
Condoms and diaphragms need to be used properly to be effective. To learn more, visit the Sexual Health Victoria website.
Emergency contraception is also known as the morning after pill. You can use it if you forget to take the Pill, have unprotected sex or if a condom breaks during sex.
The morning after pill prevents or delays ovulation – but it doesn’t always prevent pregnancy.
There are 2 types of emergency contraception pills available from a doctor or pharmacist without a prescription. The price varies depending on the pill and pharmacy.
The pills are over 85% effective and are most effective if taken within 24 hours after vaginal sex.
A copper IUD can also be used as emergency contraception if inserted within 5 days of having sex. It’s more effective than the morning after pill.
Permanent contraception can be:
- an operation to close the fallopian tubes (also known as getting your tubes tied)
or - an operation to cut the tubes that carry sperm from the testicles to the penis (a vasectomy).
Permanent contraception is over 99% effective.
An IUD is an intrauterine device, which is something that is put inside the uterus to help in the prevention of pregnancy. It is a cost-effective, highly effective method of contraception, that is a great set-and-forget option. Once it’s in, you don’t have to worry about it for the next five to 10 years.
Dr Pav Nanayakkara (00:23):
So an IUD is a fantastic option for women of any age, including young women. You don’t necessarily need to have had a baby to have one inserted, and we can insert one for you in clinic, or if you’re feeling anxious about the procedure, we have the option of inserting it asleep as well.
Dr Pav Nanayakkara (00:42):
The IUD insertion procedure is quite quick. It takes five to 10 minutes. Most patients will have mild period-like cramping discomfort during the insertion, and we recommend taking some simple pain relief before coming in to have it done. If the pain is too much or you’re too uncomfortable, we can always take a break or have a chat about inserting it in under anaesthetic. Most pain during a procedure is short-lived and will settle within a few minutes.
Dr Pav Nanayakkara (01:12):
An intrauterine device can be used for other things than contraception alone. It can be useful in the management of heavy menstrual bleeding, in period pain, and also in the perimenopause and menopause time to manage bleeding.
Dr Pav Nanayakkara (01:28):
Heavy menstrual bleeding is different for everyone. It’s any bleeding that’s significant enough that it starts to impact your life. For some people that’s changing pads or tampons every hour. For other people, it’s passing large clots or flooding their sheets. If you have any bleeding that’s starting to cause you to become tired or fatigued, it’s worth having a chat to your GP.
Dr Pav Nanayakkara (01:52):
Your doctor would start by taking a full history of your symptoms, and sometimes performing an examination. We may also order some other tests, which can include blood tests or an ultrasound scan to see what might be causing the bleeding.
Dr Pav Nanayakkara (02:08):
The management depends on the cause. We often start with simple things like increasing the iron and vitamin C in your diet, to make up for any bleeding that you’ve had that’s excessive. We also look at medical management options, which can include the oral contraceptive pill or the intrauterine device, as well as certain other hormones to help, and medications to help minimise the bleeding that you’re having overall. Lastly, we can look at surgical management options, which can include treatment of polyps, fibroids, and other conditions like endometriosis, which may be contributing.
Dr Pav Nanayakkara (02:39):
For anyone considering IUD, I would recommend coming and having a chat to your GP or a women’s health specialist for more information about the procedure.

Contraception and breastfeeding
If you breastfeed within 6 months of giving birth, it can reduce the likelihood of getting pregnant. But it’s still possible to get pregnant during this time. Breastfeeding as a natural birth control method is about 98% effective if you meet all of these conditions:
- your periods have not returned
- your baby is less than six months old
- your baby is fully breastfed and gets no other form of food or drink.
Contraception and menopause
Your fertility will decline as you age, but if you are still ovulating, it’s possible to get pregnant.
If you’re younger than 50 and you don’t want to fall pregnant, you should use contraception for at least 2 years after your final period.
If you’re 50 or older and you don’t want to fall pregnant, you should use contraception for at least one year after your final period.
Hormone therapy is not a contraceptive
Hormone therapy, such as menopausal hormone therapy (MHT), hormone therapy for endometriosis and gender-affirming hormone replacement therapy, is not a contraceptive.
Protection against sexually transmitted infections (STIs)
Most methods of contraception do not protect you from STIs. Condoms are the only form of contraception that offer some protection against STIs. Condoms can also be used with other forms of contraception, for example, the Pill.
Other barrier methods, such as dental dams (dams), can be used to prevent the spread of STIs. Dams are latex or polyurethane sheets used between the mouth and vagina or anus during oral sex.
When to see your doctor
If you’re not sure which contraception to use, see your doctor. They can explain the benefits and risks of each method.
You need a prescription for some methods of contraception, such as LARCs, vaginal rings and the Pill.
If you’re sexually active, it’s also important to have regular STI checks with your doctor or sexual health nurse.
