What is erectile dysfunction (ED), and when should I seek care?

Erectile dysfunction, or ED, is ongoing trouble getting or keeping an erection firm enough for sex. It is different from having a low sex drive, though both can happen together. One difficult experience, especially during stress or after drinking alcohol, does not by itself mean you have ED.

Talk with a clinician if erection problems keep happening or affect your well-being or relationships. You do not need to wait until the problem is severe. Mention when it started, how often it happens, and whether you still have erections during sleep or when you wake up. These details can help guide an evaluation. Results vary.

ED can be linked to diabetes, blood vessel disease, medication effects, or other health issues. A licensed physician in your state decides whether treatment is appropriate and whether you need an in-person exam or testing. New erection problems deserve attention, even if you otherwise feel well. An erection lasting more than four hours needs emergency care.
