Bob Dole is hawking Viagra. The ad, sponsored by the drugs manufacturer, Pfizer, seems to be everywhere in the print and broadcast media. Words like "courage" and "worthwhile" leap from the ad, as the former senator urges men to speak to their doctors about erectile dysfunction, the new term for impotence. In keeping with the current trend in prescription drug advertising, Viagra isnt mentioned in the ad. Instead, Pfizer is selling the illness of erectile dysfunction, or E.D., as it is referred to throughout the ad.
Safety and Tolerability

A. Some men who undergo a radical prostatectomy with one or both neurovascular bundles spared still can't achieve an erection after being injected. The nerves could play a role here but for some it has more to do with the fact that they might have anatomic variations in blood supply to the penis. Somehow blood supply has been compromised during a normal prostatectomy and this contributes to their ED. Complicate this with other risk factors, such as partial nerve injury or diabetes, and an erection can become very difficult to achieve.

The researchers focused on the paraventricular nucleus (PVN) of the hypothalamus, located in the brain, an integration center between the central and peripheral nervous systems. The site is involved in numerous functions, including erectile function and sexual behavior, and is a primary site within the forebrain that has been implicated in penile erection. The investigators also examined central nitric oxide (NO within the PVN) which plays an important role in the neurotransmission of normal penile erection.
After all the information regarding the patient's status has been gathered, the various options in management can be discussed. This is best completed in the presence of the patient and his partner. Enough options are available that every man who wants to be sexually active can do so. These include sexual counseling if no organic causes can be found for the dysfunction, oral medications, external vacuum devices, or some type of invasive therapy, including the use of intracavernosal injection therapy or the Medicated Urethral System for Erections (MUSE), which is an intraurethral suppository. One of the most difficult aspects is teaching men that sex entails more than simply achieving an erection.
Top of page The case A 46-year-old male presented to our urology clinic 1 year after sustaining an injury to his perineum. He was otherwise healthy, with no underlying medical conditions and led a very active lifestyle. The patient reported no previous traumatic injuries and presented with no other risk factors for erectile dysfunction. The injury occurred when he fell from his surf board and inadvertently speared himself with it. He described having perineal pain immediately after the injury, which continued to the date of his office visit, although with reduced severity. He also described a significant amount of bruising in the area, which subsided over time. His main complaint was that he was only able to obtain a 50–65% erection based on self report. His SEXUAL HEALTH INDEX FOR MEN score was 20. He had sought treatment from several urologists over the previous year for his erectile dysfunction, and had undergone trials of sildenafil 200 mg and tadalafil 20 mg on several occasions without improvement.

Some vacuum pumps are sold at a higher price with 100% refund within 90 days to dissatisfied users, with a somewhat lower price with 50% refund guarantee (Osbon Erecaid, ). This pump is supported by medical insurance schemes, including the UK's NHS and US Medicare and private insurers. The better-known pumps sell for prices of around 200 GBP/400 USD (2006). There is at least one vacuum pump with rings which sells for around one-fifth of this price (Noogleberry, ). Specific devices are mentioned for information only; mention should not be taken as endorsement.
This is the first demonstration that PDE5 blockade exerts an indirect, immune-mediated, antineoplastic effect through inhibition of MDSC-mediated immunosuppressive mechanisms. These findings could establish a new role for PDE5 inhibition as a viable and effective immunological adjunct in the treatment of various malignancies, thereby adding to the growing list of therapeutic applications of these agents. In this paper we show that PDE5 inhibition can significantly overcome the immunosuppressive mechanisms present in a tumor-bearing host to generate immune responses that are similar to (if not greater than) those observed in a non– tumor-bearing, vaccine-primed host (Fig. 2). However, although a CTL response can be elicited, PDE5 blockade is incapable of complete tumor eradication (Fig. S1). Several hypotheses may account for these findings. For example, chronic sildenafil blockade may up-regulate PDE5 expression, making it difficult to achieve complete and long-term pharmacologic inhibition (39). Alternatively, the sildenafil-mediated immune response against the self tumor-associated antigen can predominantly involve low affinity CD8+ T cells incapable of complete tumor cell killing. Finally, the tumor-specific immune response may ultimately result in immune editing of the tumor that escapes immune recognition (Fig. S1, C and D).

"The results of the study are probably important for people who are working at BPA factories, but the results don't support condemning BPA based on what people are exposed to at normal levels," Taylor said.
What are barrier methods?
Some men, however, experience chronic, complete erectile dysfunction (impotence), and others, partial or brief erections. Frequent erectile dysfunction can cause emotional and relationship problems, and often leads to diminished self-esteem. Erectile dysfunction has many causes, most of which are treatable, and is not an inevitable consequence of aging.
Self-injection of these agents has been of enormous benefit because they represent the most effective way to achieve erections in a wide variety of men who otherwise would be unable to achieve adequately rigid erections.
Men with a rare heart condition known as long QT syndrome should not take vardenafil since this may lead to abnormal heart rhythms. The QT interval is the time it takes for the heart's muscle to recover after it has contracted. The QT interval is measured with an electrocardiogram (EKG). Some patients have longer than normal QT intervals, and they may develop potentially life-threatening abnormal heart rhythms, especially when given certain medications. Since long QT syndrome can be inherited, men with a family history of long QT syndrome should not take vardenafil. Furthermore, vardenafil is not recommended for men who are taking medications that can affect the QT interval such as quinidine (Quinaglute, Quinidex), procainamide (Pronestyl; Procan-SR; Procanbid), amiodarone (Cordarone), and sotalol (Betapace).

Over time, high blood pressure damages your blood vessels, which can lead to erectile dysfunction. While it’s critical to get high blood pressure under control, ED is a side effect of some blood pressure control medications for some men.

In one randomized, double-blind, placebo-controlled, multi-center clinical trial conducted in China (5), 157 ED patients aged 26 to 75 with various etiologies (psychogenic, organic, and a combination of both), had an average ED history of 5 years. They all received treatment of Befar® or a placebo for 4 weeks. After the 4-week period, the Befar® patients improved their ability to have and maintain their erections by 68%. The same patients also improved the frequency and strength of their erections by 75%.
