Once you start to go through puberty, it’s possible to get pregnant or get someone pregnant, which is why it’s important to be familiar with different ways to prevent pregnancy. Abstinence, or choosing to not have or delay having sex, is the most effective form of birth control. There are also many safe and effective forms of birth control that people use, if they decide to have sex.


When people use birth control, or contraception, they use a medicine, medical device or barrier, like a condom, to keep a sperm and an egg from uniting. Condoms are one of the most widely used forms of birth control. A condom fits over an erect penis and creates a barrier that prevents sperm from meeting an egg. This barrier also helps reduce the risk of sexually transmitted diseases (STIs). Condoms are available at pharmacies, supermarkets or petrol stations without a prescription. They are also available for free at some family planning clinics. A person can buy condoms no matter their age.


Some birth control, like the Pill, the Patch and the Shot, are medicines that keep the ovary from releasing an egg or ovum. These types of birth control require a person to see a health care professional or doctor and get a prescription. These methods are very effective at preventing unintended pregnancy but not sexually transmitted diseases (STIs), which is why using a condom with one of these methods is an effective way to prevent pregnancy and STIs.

Birth control, or contraception, is a medicine, a medical device or a barrier like a condom to keep a sperm and an egg from uniting. Some birth control methods, like hormonal methods, work to keep the ovary from releasing an egg or ovum, while others help create a barrier at the opening of the cervix to keep sperm from getting inside the uterus to find an egg. Abstinence, or choosing to not have or delay having sex, is the most effective form of birth control. If someone chooses to have penile-vaginal sex, then using a condom and another form of birth control at the same time is the most effective protection possible because contraceptive methods other than internal or external condoms do not reduce the risk of sexually transmitted diseases (STIs).

The Pill, Patch, Ring and Shot

Birth control pills must be taken every day at about the same time. A package of birth control pills will last a month. They are very effective at preventing unintended pregnancy if they are taken as directed. Some methods of birth control, like the Patch and Ring, can prevent pregnancy for many weeks. A person needs to go to a health care professional or a family planning clinic to get a prescription for these methods of birth control. Many teens and young adults who have penile-vaginal sex and use the Pill, Patch or Ring also use a condom to provide an additional layer of protection against pregnancy and reduce the risk of STIs.

Depo-Provera, also known as the Shot, is a contraceptive that is injected into a person every 12 weeks and provides protection against pregnancy during that time by preventing ovulation. Like other hormonal methods of birth control, the Shot releases a hormone into the body to keep the ovary from releasing an egg. The Shot also makes cervical mucus thicker, helping to keep sperm from getting to the egg.

Long-Acting Reversible Contraception (LARC)

Using a long-acting reversible contraception, sometimes called a LARC, along with a condom is the most effective protection against unintended pregnancy and STIs. LARCs include birth control methods like the contraceptive shot, the contraceptive implant and intrauterine devices (IUDs). Each is more than 99-percent effective at preventing an unplanned pregnancy and lasts a long time.

The contraceptive implant, sometimes called Nexplanon, is about the size and shape of a matchstick. The implant releases hormones into the body to prevent pregnancy. The hormone keeps the ovaries from releasing an egg and also thickens the cervical mucus to stop sperm from getting into the uterus to find an egg. A nurse or doctor inserts the implant into your upper arm. It can provide up to three years of protection against pregnancy.

The IUD is a small piece of flexible plastic shaped like a T. A health care professional inserts the IUD into the uterus. Some IUDs have copper wire, while others release hormones into the body. Both make it difficult for sperm to get to an egg. IUDs can last for years depending on which one a person has inserted. Some last for up to five years and some for up to 12! When a person is ready to have a baby, a health care professional can simply take the IUD out, and a person is able to get pregnant after that.

While all of these hormonal methods are highly effective at preventing pregnancy, none provide protection against STIs. So it’s important to also use a latex condom when you have sex.


Parents or guardians can start talking with their children about pregnancy and how to prevent it before their children become sexually active. When parents and guardians talk with their children about these topics, children learn that they can come to their parents if and when they have questions. Below are some ways to start these conversations:
