Patient's question:
Unable to achieve an erection, the penis has become shorter.Doctor's answer:
Erections can occur normally without indicating impotence.Advice: Impotence, also known as erectile dysfunction (ED for short internationally), refers to the inability to achieve or maintain an erection during sexual arousal, or the ability to achieve an erection with some degree of hardness but not sustain it for sufficient time to complete intercourse, thereby hindering or preventing sexual activity. Impotence is classified into congenital and pathological types. The former is rare and difficult to cure, while the latter is more common and has a higher cure rate.
