Penile discharge testing is a medical evaluation used to identify the cause of any abnormal fluid coming from the penis. This discharge can appear clear, white, yellow, or green and is often linked to infections, especially sexually transmitted infections (STIs). Testing helps determine the exact infection so the right treatment can be started quickly.
Most doctors perform penile discharge testing using a combination of:
Urine test – checks for STIs like chlamydia and gonorrhoea.
Swab test – a small swab is taken from the urethra to look for bacteria or inflammation.
Blood tests – used to rule out other infections if needed.
Physical examination – to check for symptoms such as pain, swelling, or sores.
When should someone get tested?
You should consider testing if you notice any of the below symptoms:
Unusual discharge (white, yellow, green, or foul-smelling)
Pain or burning during urination
Itching or irritation around the urethra
Pelvic or testicular discomfort
After unprotected sexual contact
If a partner tests positive for an STI
Why is testing important?
Untreated infections can lead to complications such as urinary issues, infertility, testicular inflammation, or ongoing discomfort. Testing is quick, confidential, and usually gives results within a few days. Most infections are easily treatable once identified.
Can penile discharge go away on its own?
Not usually. Even mild discharge can indicate an infection that needs medication. Avoid self-diagnosing and do not start antibiotics without medical guidance, as this can make the infection harder to treat.
How to prepare before testing?
Avoid urinating for at least 2 hours before your appointment (for accurate urine testing).
Inform the doctor about recent sexual activity or symptoms.
Bring a list of any medications you are taking.
If someone notices any form of discharge, it’s best not to delay. Early testing and treatment help prevent further spread of infection and ensure faster recovery.
