In the realm of sexual health, there are many methods available to prevent unintended pregnancies and protect against sexually transmitted infections (STIs).

One such method, contraceptive implants, has gained popularity for its effectiveness in preventing pregnancy. However, a common question that often arises is whether these implants can also offer protection against STIs.

In this blog, we’ll explore the facts surrounding contraceptive implants and their role in preventing STIs so that you can figure out the right contraception method for you.

Understanding contraceptive implants

Contraceptive implants are small implants placed just under the skin of the upper arm. These implants slowly release a hormone called progestin into the body, which primarily works by preventing ovulation, thickening cervical mucus, and altering the uterine lining. This combination of effects is highly effective at preventing pregnancy, with a success rate of over 99%.

While contraceptive implants are a great choice for contraception, they do not provide a physical barrier against the transmission of infections.

Preventing STIs: the importance of safe sex

It is essential to recognise that contraceptive implants are not a substitute for practising safe sex. The only proven ways to reduce the risk of contracting or transmitting STIs are through the use of barrier methods like condoms, dental dams, and regular testing.

If you’re sexually active, you should take appropriate precautions to protect yourself and your partners.

Reassuring aspects of contraceptive implants

While contraceptive implants do not prevent the transmission of STIs, they offer some reassuring benefits when it comes to sexual health.

Pregnancy prevention

Contraceptive implants are exceptionally effective in preventing pregnancy. This can offer peace of mind to those who are not yet ready to start a family.

Long-lasting protection

One of the significant advantages of contraceptive implants is their longevity. They can provide contraception for up to three years, reducing the need for daily or monthly contraceptive management.


Contraceptive implants are a low-maintenance option. Once they are inserted, there is little to no day-to-day effort required, unlike other methods such as the contraceptive pill.


If you decide to become pregnant or choose a different method of contraception, the implant can be removed, and your fertility will return to its natural state.

Final thoughts

Contraceptive implants are a valuable contraceptive method but do not protect against STIs. To ensure your sexual health, always remember to use barrier methods, get regular STI testing, and have open, honest discussions with your partners about your sexual health needs and preferences. By staying informed and taking the necessary precautions, you can enjoy a safe and satisfying sex life while protecting your overall well-being.
