Erectile dysfunction is a problem that typically develops over time, but it can occur suddenly and unexpectedly as well. In cases that develop gradually, it is often a circulatory or nervous system issue.

Does erectile dysfunction just happen suddenly?

That's what doctors call erectile dysfunction, or ED. If it happens only occasionally, it's not likely to be serious. All men have problems with erections at some time in their lives. If it slowly but consistently gets worse, there's probably a physical cause.

Does erectile dysfunction happen overnight?

Causes of erectile dysfunction

Physical erectile dysfunction happens over a period of months or years, and is often a gradual loss of function. If erections still occur spontaneously overnight or in the morning, the problem may be psychological.
