Frequently asked questions

Can penile rash be caused by an STI?

It can be associated with STIs, but many non-STI causes also exist. Symptoms alone cannot diagnose an infection.

Should I test immediately?

Testing timing depends on the concern and possible exposure. A clinician can advise whether testing now, later or after symptoms change is most appropriate.

Can symptoms have more than one cause?

Yes. Inflammation, skin conditions, urinary problems and infections can overlap. A careful history and examination help narrow the possibilities.
