Erectile dysfunction refers to the inability to attain a full and functional erection, or inability to attain an erection at all. Viagra addresses only this one issue, that of improving the ability to have a full erection. Before writing out a perscription, most doctors will suggest an evaluation. First of all we look for what may be interfering with sexual functioning. Medicines can lead to loss of libido, or interfere with erection or ejaculation in men, and delay or prevent orgasm in women.
Common culprits are blood pressure medicines, sedatives and mood elevators.
Alcohol may increase libido, but can prevent erections. Pain, injuries, diabetes, vascular disease can interfere with the erectile mechanism. Psychological factors such as performance anxiety may become prominent issues in someone with partial loss of function. Diagnostic testing may seek to identify biochemical deficiencies such as loss of male hormone production. Medication lists will be helpful to look for chemical interference.
