Erectile dysfunction (ED) is a common problem affecting millions of men globally. Most men undergo at least one episode of being unable to achieve an erection or sustain it when desired. However, it should be a cause of concern if it is a recurrent issue. If you have a low sexual drive and cannot get or maintain an erection, you may have erectile dysfunction. ED is a broad term. However, it does not involve cases where a person with a normal erection has issues with ejaculation or orgasms. Such symptoms are associated with premature ejaculation. Erectile dysfunction can cause psychological problems like stress and low confidence, affecting your relationship with your partner.
