Condoms

When used correctly, condoms reduce the likelihood of pregnancy and many sexually transmitted infections. Use a new condom for every sexual act, from the first genital contact. If it tears or slips off, prompt assessment may be needed for emergency contraception, STI tests or HIV PEP.

  • Condoms are the only widely used contraceptive method that reduces the likelihood of both pregnancy and many STIs.
  • Protection is best when a new condom is used correctly from the start for every act of vaginal, anal or oral sex.
  • Never use two external condoms together, or an external and internal condom together; extra friction increases the likelihood of tearing.
  • Water-based or silicone-based lubricant is safe for latex; oil may damage latex.
  • After tearing, leaking or slipping off, emergency contraception, STI tests, hepatitis care or HIV PEP may be needed.
  • HIV PEP is time-critical: have it assessed as soon as possible and within 72 hours at the latest.

Sexually transmitted infections (STIs)An STI is an infection mainly passed on through sexual contact. Many STIs cause no symptoms. Testing, appropriate treatment, partner notification and safer sex prevent complications and further transmission.
S
SexSexual health includes physical and emotional wellbeing, pleasure, safety, respect, boundaries, relationships, STI prevention and pregnancy. Sex should be voluntary: everyone can stop at any time. Condoms reduce STI and pregnancy risks, but no method provides complete protection.
H
Had sex and do not want to become pregnantAfter sex without reliable contraception, emergency contraception can reduce the chance of pregnancy. The sooner you seek advice, the more options are usually available. Emergency contraception does not end an existing pregnancy and does not protect against STIs.
