Understand symptoms

Many STIs cause no symptoms. Symptoms alone can never reliably identify an STI. Testing is the only way to know.

Symptoms in men Discharge, burning, sores, testicular pain. Symptoms in women Discharge, pelvic pain, bleeding, sores. STIs without symptoms Why silent infections still matter.

When should you get tested?

After a possible exposure. Timing depends on the infection and test type (window periods differ).
When you have genital symptoms such as discharge, sores, burning, or pelvic pain.
As routine screening if you are sexually active. Ask a clinician what fits your situation.
