Erectile Dysfunction Statistics

erectile dysfunction statistics


Erectile dysfunction (ED) is defined as the inability to attain and/or maintain penile erection sufficient for satisfactory sexual intercourse. ... The Massachusetts Male Aging Study (MMAS), a substantial epidemiological survey quantitated the prevalence of ED in a non-institutionalized population of men.


If it is determined that ED is a problem, the patient evaluation should include a detailed sexual and medical history and a physical exam. In particular, it is important to evaluate the ED within the context of ejaculatory problems. There is a strong interplay between premature ejaculation (PE) and ED, with about a third of ED patients reporting PE. The relationship between the PE and ED is bidirectional and successful treatment of one often requires treatment of the other.14

A number of specific questions relating to sexual function can help the clinician evaluate the complaint of ED. Questions should focus on the following:

  • How long has ED been a problem, and did it start gradually or suddenly?
  • How frequently do you have intercourse currently, and how frequent was it in the past? Do you have difficulty with penetration and/or loss of the erection during intercourse in the absence of premature ejaculation?
  • How firm are your erections (use a scale of 1 to 10)? Do your erections vary under different circumstances, such as with different partners, oral stimulation, or masturbation?
  • Do you have morning or evening erections and, if so, what is the quality of these erections?
  • Is there any new curve or bend to your penis to suggest Peyronie’s disease? If curvature is present, is it painful? What are the location and severity of the curvature?
  • Are you having any difficulties with sexual desire, arousal, ejaculation, or orgasm? If so, did these difficulties occur with the onset of the erectile dysfunction or are they separate issues?

How common is Erectile Dysfunction?

About 5 percent of men that are 40 years old have complete erectile dysfunction, and that number increases to about 15 percent of men at age 70. Mild and moderate erectile dysfunction affects approximately 10 percent of men per decade of life (i.e., 50 percent of men in their 50s, 60 percent of men in their 60s). Erectile dysfunction can occur at any age, but it is more common in men that are older. Older men are more likely to have health conditions that require medication, which can interfere with erectile function. Additionally, as men age, they may need more stimulation to get an erection and more time between erections.


Measures for de-addiction play an important role in the overall management of ED. The most common co-morbid disorders were urological, like BPH, LUTS, etc, followed by cardiovascular, psychological and diabetes. Overall, rational pharmacotherapy was observed.

Tadalafil was the most commonly prescribed drug for ED. The main factor in the selection of a particular PDE5 inhibitor was its pharmacokinetics and cost. Udenafil, being the costliest, was the least prescribed. Dapoxetine was used in a significant number of individuals primarily for PE with ED. The combination of Papaverine, Chlorpromazine ± Alprostadil was used as intracavernosal injection in patients not responding to oral drugs.
