If you are worry about reliability of your erection you will probably want to visit a doctor. Take into consideration that young men often experience this problem. So, episodic erectile dysfunctions do not signify that you will have constant problems in the future.

A doctor may ask you about your health state and whether you ever have an erection. Questions about changes in your life which can affect your sexual health as well as drugs you take can also help a doctor to determine impotence.

Measuring blood pressure and checking the pulses in your legs are helpful methods to determine how active your circulation is. A doctor will analyse your penis and scrotum as well as, perhaps, your prostate gland. Blood tests can be done to eliminate other disease.

A specialist may inquire about your personal relationship with your partner and other physical or psychological aspects of your private life. Your partner can be also present at your medical check up. Menopause, for instance, can make sexual intercourse rather uncomfortable for a woman.  

Sometimes if a doctor considers it reasonable, he or she may advise you to take more specific tests to estimate your nerves condition and your blood flow.
