Erectile dysfunction is the inability to either achieve or maintain an erection. This may happen either occasionally or regularly, but may occur only in certain situations depending on the cause (i.e. patients may still have early morning erections).
Avanafil has similar adverse effects as the other PDE5 inhibitors but is not associated with the visual changes of sildenafil or muscle aches of tadalafil. .
Rarely, a doctor may perform an angiogram (injecting a dye into the arteries that supply the penis and taking X-rays to look for areas of narrowing of the arteries) in cases in which possible vascular surgery could be beneficial.
The earlier you get a diagnosis of ED, the sooner you can start on treatments that can help your symptoms.
There are other similar medicines called tadalafil (Cialis), vardenafil (Levitra) and avanafil (Spedra) that work in a similar way. Buying Viagra online
Some men with erectile dysfunction report having either a partial erection that is unable to sustain sexual intercourse, or the total absence of swelling of the penis. The severity of erectile dysfunction can be assessed using the International Index of Erectile Function (IIEF-5), which uses a questionnaire to grade ED as either mild, moderate or severe.
It is important to remember that having sex can put additional strain on the heart and may increase your risks if you have a history of heart disease or have an existing heart problem. The most common side effects of erectile dysfunction treatments include headaches, a sudden feeling of heat in your upper body, indigestion, visual disturbances, dizziness or a stuffy nose. Side effects are usually mild to moderate and don’t last long. If you experience any side effects or perhaps an increase in the severity of a side effect, you should stop taking the medication.
As blood flows into the penis, the corpora cavernosa swell, and this swelling compresses the veins (blood vessels that drain the blood out of the penis) against the tunica albuginea. Compression of the veins prevents blood from leaving the penis. This creates a hard erection. When the amount of cGMP decreases by the action of a chemical called phosphodiesterase type 5 (PDE5), the muscles in the penis tighten, and the blood flow into the penis decreases. With less blood coming into the penis, the veins are not compressed, allowing blood to drain out of the penis, and the erection goes down. Could Semen Hold Key to New OTC Contraceptive?

Stem cell therapy is an attractive treatment modality and an appealing option for tissue regenerative therapy for ED. Stem cells are pluripotent cells that can be produced from multiple regions within the body. They have the potential to divide and differentiate into numerous kinds of human cells, such as endothelial cells and smooth muscle.79 The efficacy and safety of gene and stem cell therapy in patients with ED and IHD need to be extensively investigated because both seem to have the potential to correct underlying abnormalities in ED. This would be a huge development in terms of management options for patients with ED and IHD.

If you have a neurological disorder or spinal cord injury and other erectile dysfunction treatments aren’t effective, two types of surgical implants could offer solutions to your ED. “An implantable pump can be used to manually create an erection by pumping fluid into cylinders placed inside the penis,” explains Feloney. “The other option is a malleable prosthesis that works like a gooseneck lamp to direct the penis into position for intercourse." Risks for these ED treatments include infection and mechanical breakdown.
We all know that erectile dysfunction and premature ejaculation are the most demoralizing experiences that we can have as men. That is why it sickens me that many companies and gurus out there are trying to make money from our insecurities by selling us products which are essentially pseudoscientific hype. That's why this book cuts through the fluff and focuses on simple solutions that have been proven to work.
These tests are only done in certain patients who have not responded to initial therapies, and may include: Ultrasonography (penile Doppler) to check blood flow in the penis A special injection into the penis to check erection Arteriography (an imaging test that uses X-rays and a special dye to see inside the arteries) Magnetic resonance imaging (MRI) or computed tomography (CT) scan Nocturnal penile tumescence or NPT (using a special electronic device to monitor nocturnal erections)

Preventing or treating erectile dysfunction could also combat these underlying conditions.
The vascular endothelium has an important role in angiogenesis and vascular repair by producing regulatory substances, including NO, prostaglandin, endothelins, prostacyclin and angiotensin II. These regulatory factors regulate the blood flow to the penis by controlling smooth muscle contractility and subsequent vasoconstriction and vasodilatation. Generally, in erectile tissue, increased blood flow through the cavernosal artery increases shear stress and produces NO, which further relaxes the vascular smooth muscles and increases blood flow in the corpora cavernosa.54 These events cause penile erection. However, in ED, endothelial NO synthesis is reduced and there is increased endothelial cell death (Figure 2).55 Pathophysiology of Erectile Dysfunction and Ischaemic Heart Disease
