Information on Erectile Dysfunction at the National Kidney and Urologic Diseases Information Clearinghouse
ED is the inability to get or keep an erection firm enough for sexual intercourse. ED can be a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. ED is sometimes called impotence, but that word is being used less often so that it will not be confused with other, nonmedical meanings of the term. The National Institutes of Health estimates that ED affects as many as 30 million men in the United States.1 Incidence increases with age: About 4 percent of men in their 50s and nearly 17 percent of men in their 60s experience a total inability to achieve an erection. The incidence jumps to 47 percent for men older than 75.2 But ED is not an inevitable part of aging. ED is treatable at any age. More at the NIDDK/NIH.
Information on Erectile Dysfunction from Johns Hopkins James Buchanan Brady Urological Institute
Erectile dysfunction, also termed impotence, refers to the inability to obtain or maintain an erection that is firm enough or lasts long enough to have satisfactory sexual intercourse. The problem affects almost all men at one time or another in their lives. It affects as many as 30 million American men, including 30% of men between the ages of 40 and 70. While erectile dysfunction often devastates those affected by it, out of fear, embarrassment, or countless other reasons, few men seek treatment. However, the problem is almost always treatable..Read more from Johns Hopkins Medicine.
Information on Impotence at the University of Pittsburgh Medical Center
Erectile dysfunction, also called impotence, is the inability to attain or maintain an erection of the penis that is firm enough for penetration during sexual intercourse. To initiate and maintain an erection, the penis must fill with blood. Nerve signals stimulate this engorgement. They prompt the blood vessels in the penis to expand so blood can fill it. Meanwhile, other blood vessels constrict, trapping blood inside. More at University of Pittsburgh Medical Center.

Abstract: Sildenafil citrate 100 mg starting dose in men with erectile dysfunction in an international, double-blind, placebo-controlled study: effect on the sexual experience and reducing feelings of anxiety about the next intercourse attempt.
INTRODUCTION: Sildenafil citrate 50 mg is the recommended starting dose for men with erectile dysfunction (ED); however, most men are later titrated to sildenafil 100 mg for improved efficacy. AIM: Assess the tolerability and efficacy of sildenafil initiated at the 100-mg dose in men with ED. Abstract available at PubMed.
Effect of Lifestyle Changes on Erectile Dysfunction in Obese Men
Erectile dysfunction is an important cause of decreased quality of life in men, and may affect an estimated 30 million men in the United States. In the Health Professionals Follow-up Study, moderate to severe erectile dysfunction was reported by 12% of men younger than 59 years; 22% of men aged 60 to 69 years; and 30% of men older than 69 years. Moreover, several modifiable lifestyle factors, including physical activity and leanness, were associated with maintenance of erectile function. For instance, men with a body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) higher than 28.7 have a 30% higher risk for erectile dysfunction than those with a normal BMI (25).

Erectile Function and Risk of Parkinson’s Disease
The autonomic nervous system is often affected in Parkinson’s disease (1–3), and erectile function, which is controlled by the autonomic system, is commonly compromised (1, 4–7). An important question is whether erectile dysfunction precedes the onset of motor symptoms of Parkinson’s disease. If so, examination of erectile function could eventually contribute to the identification of men who are at high risk or in a preclinical stage of Parkinson’s disease.

Abstract: Efficacy and safety of tadalafil once daily: considerations for the practical application of a daily dosing option.
OBJECTIVE: To provide clinically relevant information on tadalafil 2.5 or 5 mg once daily for the treatment of erectile dysfunction (ED), by reviewing safety and efficacy study findings. Findings from an integrated analysis of trials of tadalafil 10 and 20 mg as needed are presented to provide context for the daily dosing regime. See Abstract at PubMed.
Penile rehabilitation following treatment for prostate cancer: an analysis of the current state of the art
Despite recent advances in surgical technique using laparoscopic and robotic approaches for the management of early organ-confined prostate cancer, most contemporary reports demonstrate significant rates of erectile dysfunction comparable to standard open approaches. Controversy remains related to many of the pre-and postoperative management strategies, including agents to enhance nerve recovery, erectogenic drugs, antioxidants, vasoactive injectables, vacuum erection devices and nerve grafting procedures. Additionally, the optimal timing of these interventions and their duration, dose, frequency and outcome thresholds remain ill-defined. In our paper, we provide a comprehensive literature review involving both the basic and clinical data surrounding rehabilitative approaches. Full text available free through PubMed.

We've got 30 million answers to that question.
