What is the single most effective way of limiting sexual infections?

Condoms. They're the single most effective way to reduce the risk of STIs during sex.

Condoms create a barrier that stops bodily fluids from being exchanged, which is how most STIs are transmitted. They protect against HIV, chlamydia, gonorrhoea, and many others. No other method of contraception does this. The pill, the implant, the coil: none of them protect against STIs. Only condoms.

They're not 100% effective because some STIs (like herpes and HPV) can be spread through skin-to-skin contact in areas the condom doesn't cover. But they're still the best protection available during sex.

Getting tested regularly is the other big one. A lot of STIs have no symptoms, so you could have one and not know. Regular testing means you catch things early and avoid passing them on.

Condoms are the most effective way to reduce the risk of sexual infections during sex.

Condoms stop body fluids from being shared between people. This is how most STIs are passed on. No other type of contraception protects against STIs. The pill, the implant, and the coil only prevent pregnancy.

Condoms are not 100% perfect because some STIs like herpes can spread through skin touching skin. But they are still the best protection there is.

Getting tested regularly is the other important thing. Many STIs have no symptoms, so testing is the only way to catch them early.
