The article details three studies performed on American men: a 24- 34 week dose-response study of 532 men treated with oral sildenafil or placebo, a 12-week flexible dose-escalation study of 329 men treated with oral sildenafil or placebo, as well as a 32-week doseescalation, open-label extension study of 225 of the 329 men. In all three of the studies, men were excluded if they had penile anatomical defects, a primary diagnosis of another sexual disorder (ex. premature ejaculation,Low Cost Viagra), spinal cord injury, any major psychiatric disorder not well controlled with treatment, poorly controlled diabetes mellitus, active peptic ulcer disease, a history of alcohol or substance abuse, major hematologic, renal, or hepatic abnormalities, or a recent (within the past six months,Low Cost Viagra) stroke or myocardial infarction, or receiving nitrate therapy (Goldstein et al., 1998). Although the age characteristics of the study population was similar to that of subsequent studies of actual patients (mean age of 61 years), the characteristics of actual sildenafil users differ substantially from those of the subjects who participated in the widely-publicized clinical trials done by the Sildenafil Study Group in 1998. Harrold et al. agree, noting that their study cohorts, as well as those of other researchers, were significantly more likely to have concomitant conditions such as hypertension, ischemic heart disease, hyperlipidemia, and diabetes mellitus (2000,Low Cost Viagra). Salonia et al. report on a study by Padma-Nathan and colleagues regarding the long-term safety results from patients who have been exposed to sildenafil for up to 4.5 years (2003). The study found that the incidence of reported side effects was higher, ranging from 16% to 63% more than those reported in clinical trials. As such, data from the Goldstein et al. randomized clinical trials may present a picture that is overly optimistic regarding the effectiveness and tolerability of the treatment, owing to careful patient selection as well as to intensive patient surveillance and monitoring. One of the safety issues with Viagra is that many of the men most likely to use it also have other health issues which were not addressed by Pfizer-sponsored research. This is why Goldstein’s trial on primarily healthy men is so misleading.Dinner was fabulous. The conversation is flowing even better than the wine. Excitement and anticipation is in the air.

Erectile Dysfunction – What exactly is it?
The traditional Latin term impotentia coeundi refers to the simple inability to insert the penis into the vagina. This general term has since been replaced by more clinical definitions to characterize erectile dysfunction. These definitions vary somewhat, but following are examples from official medical sources to provide a general idea: “Erectile Dysfunction is the inability of the male to attain and maintain erection of the penis sufficient to permit satisfactory sexual intercourse.” – National Institutes of Health Consensus Development Conference on Impotence; December 1992 “Erectile Dysfunction is the persistent or repeated inability, for at least 3 months duration, to attain and/or maintain an erection sufficient for satisfactory sexual performance.” – Process of Care Consensus Guidelines Panel; December 1997 “Erectile Dysfunction is the consistent or recurrent inability of a man to attain and/or maintain a penile erection sufficient for sexual performance.” – 1st International Consultation on ED sponsored by the World Health Organization, July 1999 Erectile Dysfunction (ED,Low Cost Viagra) is a form of impotence, commonly defined as the consistent inability to achieve or maintain an erection sufficient for mutually satisfying sexual intercourse, or another chosen sexual activity, regardless of the capability of ejaculation. The word “consistent” is included in the definition because most men experience transient episodes of ED that are temporary and usually associated with fatigue, anger, depression, or other stressful emotions. There are some varying threshold frequency definitions that may be applied by clinicians to further characterize ED. For example, ED is indicated if it happens 25% of the time, or 50% of the time for a period greater than three months, or six months. Primary erectile dysfunctionis a relatively rare condition in which a man has never been able to develop an erection.
