What does impotent mean?

Impotent means that a person with a penis is unable to get and/or maintain an erection, or ejaculate regularly. It is also known as erectile dysfunction. An erection happens when the brain sends a signal to the body to fill the penis with blood, making the penis harder. Erectile dysfunction can happen for many different reasons, including mental, emotional and physical factors. If it is something you are concerned about, you can talk to a health care provider.
