Erectile Dysfunction (ED) is the condition of not being able to maintain an erection during sex. Jeopardizing personal relationships and contributing to other side-effects, the ongoing problem can become a serious matter of concern. Lifestyle, poor diet, and underlying psychological conditions can result in this problem, limiting the scope of starting a new family with their beloved.

Diagnosis
The diagnosis process initiates with the doctor asking questions about the person’s medical history.

NPT Test
A nocturnal penile tumescence test is followed using a battery-powered, portable device that one can wear on his thigh at the time of sleeping. Through this device, the quality of nocturnal erections is evaluated. The doctor can make use of the data later.

Treatment
Men undergoing issues with erectile dysfunction find it hard to open about the problem and do not receive treatment at the proper stage. However, the problem can go away if one follows proper treatment that may include assistive devices like pumps and certain medications.

Medications
When the person visits the doctor, he will be prescribed with the best ED medicine for helping tackle the symptoms. The medications may have side-effects, and if one faces any sign of issues, it is best to consult with a medical professional. The following list is that of the best ED medicine available today.

• Sildenafil (Viagra)
  It is the best ED medicine available  and is an oral tablet that should be taken an hour before sex and only once per day. However, vision changes, flushing, stomach upset and headaches are common side-effects.
• Alprostadil (Caverject)
  Available as an injection solution, it is injected in the penis a few minutes before sex. The patient can take this no more than three times per week; irritation and redness are common side-effects.
• Vardenafil (Levitra)
  By de-stressing the arteries, this best ED medicine improves blood flow during penile dysfunction. Nitric oxide is released when you take a 10 mg dose. Additionally, one can take this medicine every day and 25-30 minutes right before sex.
• Avanafil (Stendra)
  For treating ED orally, this medicine is taken 15 minutes before sex. The use of nitrates should be reduced to a minimum while taking Avanafil as it can result in premature mortality or low blood pressure. Warming and reddening of the face, ringing in ears, hearing sounds differently and flushing is adverse results of taking this medication.
• Testosterone (Androderm)
  The level of testosterone generally decreases over the course of time, and it results in penile dysfunction along with low sex drive, fatigue, and decreased sperm count. The Food and Drug Administration refers to the fact that patients with this health condition should know about certain side-effects, including prostate growth, acne, and moodiness.
