Depression and anxiety: Psychological factors may be responsible for erectile dysfunction. These factors include stress, anxiety, guilt, depression, widower syndrome, low self-esteem, posttraumatic stress disorder, and fear of sexual failure (performance anxiety). It is also worth noting that many medications used for treatment of depression and other psychiatric disorders may cause erectile dysfunction or ejaculatory problems.
Care for these patients, who in many cases are emotional, demanding, and time consuming, may evoke feelings of frustration and anticipatory anxiety in the time-strapped urologist. Early in the encounter, the urologist must understand the patient’s psychosocial environment and establish a rapport and meaningful alliance with the patient and his family, if present (13). It is important to ensure that the doctor-patient interaction is informative and task oriented for greater patient buy-in and compliance with treatment (13,14). Affirm to the patient that regardless of the short time allotted for the visit that the doctor-patient relationship will endure even after the visit. This may be accomplished through a scheduled follow-up telephone call, electronic message, follow-up clinic visit, or a written letter. It may also be beneficial to refer the patient to a sex therapist or counselor though many young men will reject the idea that there is a psychosocial element to their ED and may refuse to consider therapy.
The penis is composed of three cylinders: two on the top, the corpora cavernosa and one on the bottom, the corpus spongiosum. All of these are involved in the process of an erection. The corpora cavernosa are composed of potential spaces that can distend with blood, causing rigidity of the penile shaft. The corpus spongiosum is important for rigidity of the glans of the penis. When aroused, stimulated chemicals are released from the nervous system (nitric oxide is one) that stimulate the arteries to the penis to relax and increase blood flow into the penis. These potential spaces, like a sponge, can expand when more blood flow comes in the penis. Each corpora cavernosa is surrounded by an outer coating the tunica albuginea. When the penis fills with blood, these potential spaces, the sinusoids, compress the veins in the corpora against the side of the tunica albuginea, thus preventing blood from leaving the penis. It is this compression of the veins that allows for the erection to become fully rigid.
The number of sexual dysfunction complaints was significantly associated with the amount of alcohol consumed per day. On curve-fitting the data, there was a significant positive linear relationship (F = 10.54; dF 87; P = 0.002) [Figure 1]. However, there was no correlation between the reduction in frequency of sexual intercourse over the last five years and the amount of alcohol consumed.
Depression. The profound sadness, emptiness, and hopelessness that characterize depression may also cause ED among younger men. “The biggest effect of depression is on a man’s desire for sexual relations, or libido,” says Drogo Montague, MD, director of the Center for Genitourinary Reconstruction in the Glickman Urological and Kidney Institute at the Cleveland Clinic. “To some extent, depression can affect a man’s ability to maintain an erection. It can be a chicken-and-egg situation. However, reduced libido is a common indicator of depression.”
Similar to the general population (58), in subjects consulting for sexual dysfunction, T deficiency is progressively more prevalent as a function of age (50). In a series of 4,890 subjects consulting our Sexual Medicine and Andrology Unit for sexual dysfunction, one in five (19.6%) and one in three (29.4%) patients have total T below 10.4 and 12 nmol/L, respectively (60). Clinical correlates of T deficiency show different figures according to patient’s age. In fact, we previously demonstrated that in the youngest quartile (17–42 years old), but not in the oldest one (62–88 years old), severity of reported ED and penile blood flow impairment (dynamic peak systolic velocity) were not associated to decreasing testosterone levels (50). It is possible to speculate that, in young individuals, intercourse-related penile erection is such a complex phenomenon that other determinants (i.e., intrapsychic or relational) might mask its androgen regulation and that T deficiency produces greater sexual disturbances in subjects with greater frailty, such as older individuals. However, reported frequency of spontaneous erection and sexual thoughts were significantly decreased as a function of T decline even in younger subjects (50). Moreover, in young individuals low T was associated with a worse metabolic profile, including hypertriglyceridemia and increased waist circumference (50). Accordingly, the prevalence of MetS in the youngest quartile was clearly associated with T deficiency, as it was in the older quartiles (50). Therefore, T deficiency must be accurately verified in all subjects consulting for sexual dysfunction, even in the youngest ones.
Once observed that the organic component of ED is the most important one in younger patients (Figure 2), the summarized evidence underlines that metabolic and CV risk must not be underestimated in younger men even when they are apparently healthy. In fact, it is particularly in these men that recognizing the presence of risk factors can help in changing life-style, thus really changing the natural history of metabolic and CV diseases. In older men the damage is often already established and the identification of further risk factors usually does not add information to the estimation of CV risk. ED is a symptom that can provide a chance for both the patients and physicians to unearth the presence of CV risk factors and improve both the quality and length of life of these men.
These are not currently approved by the FDA for ED management, but they may be offered through research studies (clinical trials). Patients who are interested should discuss the risks and benefits (informed consent) of each, as well as costs before starting any clinical trials. Most therapies not approved by the FDA are not covered by government or private insurance benefits.
Having erection trouble from time to time isn't necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease.
Additionally, speaking to more than just the sexual issues related to erectile dysfunction, the research addresses implications related to the overall understanding of penile health. According to Arthur Burnett, M.D., a professor of urology and head of the research team, "eNOS plays roles in both immediate erectile response and the overall health and function of the penile tissue."
Other hormone levels: Measurement of other hormones beside testosterone (luteinizing hormone [LH], prolactin level, and cortisol level) may provide clues to other underlying causes of testosterone deficiency and erectile problems, such as pituitary disease or adrenal gland abnormalities. Doctors may check thyroid levels in some individuals as both hypothyroidism (low thyroid function) and hyperthyroidism (overactive thyroid function) can contribute to erectile dysfunction.
L-arginine is an amino acid that occurs naturally in the human body and helps make that magic nitric oxide so important for supporting an erection. A 1999 study observed the effects of six weeks of L-arginine administered daily among men with ED. One third of those who took five grams per day of L-arginine experienced significant improvements in sexual function.
Erectile dysfunction in young men is an increasingly common chief complaint seen in urology clinics across the world (1). The international urologic community has taken an increased interest in this topic, with experts in the field of andrology and sexual dysfunction publishing multiple review articles (2,3) and an AUA Update Series Lesson (4) dedicated to this concerning issue. These articles skillfully address the epidemiology and diagnostic evaluation of ED and categorize ED (Table 1) into psychogenic or organic causes, addressing treatment options with specific interventions for each of the most common diagnoses.
Erectile dysfunction is a common problem for more than half of men with diabetes. Musicki says that an estimated "50 percent to 75 percent of diabetic men have erectile dysfunction to some degree, [a rate] about threefold higher than in non-diabetic men." This is not the same type of erectile dysfunction seen in non-diabetics, and it is less effectively treated with conventional drugs like Viagra.
"One of the reasons erectile dysfunction increases with age is that the diseases that lead to it also increase with age," notes Dr. Feloney. Evaluating the causes of erectile dysfunction starts with your doctor taking a good health history and giving you a physical exam. Common medical issues that can lead to erectile dysfunction include diabetes, high blood pressure, hardening of the arteries, low testosterone, and neurological disease. Talk to your doctor about better managing these health conditions.
Currently, there are no therapies that cure erectile dysfunction. However, a number of effective therapies are available that allow an individual to have an erection when desired. Depending on the cause of the erectile dysfunction, certain therapies may be more effective than others. Although there is limited data on lifestyle modification, intuitively, decreasing risk factors for erectile dysfunction may help prevent progression of disease.

Look, ED can have many causes. Most of the time, it’s physiological. But there are also lots of psychological reasons why someone may experience ED. Treating ED isn’t all about medication. Dealing with some of these psychological issues can help you battle ED, too. I’m talking about depression, anxiety, loss of desire, sense of inadequacy, guilt, fatigue, anger, relationship dysfunction. Working through these types of psychological challenges can help you achieve the happy, healthy manhood you deserve.
Penile Injection Medication: This is just what it sounds like. Injected at home directly into the penis, the medication alprostadil produces erection by relaxing certain muscles, increasing blood flow into the penis and restricting outflow. Although some sources report an 80 percent success rate, the therapy has disadvantages, such as risks of infection, pain, and scarring—fibrosis—in the penis, and it may also cause priapism. A popular version of this medication is Upjohn Corporation’s Caverject. The MUSE System, by VIVUS, involves the same medicine (a pellet of alprostadil) applied with an eye-dropper-like applicator, directly into the urethra.
