Unconventional CV risk factors, such as impaired erections during masturbation and reduced flaccid acceleration, are interesting parameters to implement in Sexual Medicine context, because they can help fill the gap of information on CV risk, left by the conventional risk factors (the so-called residual risk) (38). However, it should be recognized that not all the healthcare professionals who deal with the complaint of ED (i.e., general practitioners, diabetologists, cardiologists, sport physicians, nurses, etc.) have the facilities or competence for the specific assessment of these parameters. In contexts different than Sexual Medicine and Andrology, the assessment of conventional risk factors is certainly more convenient. Metabolic syndrome (MetS) represents a cluster of metabolic derangements easily and commonly evaluated in several different medical contexts. In a population of more than 600 subjects attending the Sexual Medicine and Andrology Unit of the University of Florence for ED, the presence of MetS was associated with an increased incidence of MACE during 4.3 years of follow-up in younger (first tertile of age: 18–52 years) (Figure 3, Panel A and B) but not in middle aged and older men (second and third tertiles of age: 53–60 and 61–88 years, respectively) (Figure 3, Panel B). Similar to MetS, the algorithms for estimating the risk of developing MACE are easily computed and they take into account factors largely available in a clinical setting. In Europe, the most commonly used algorithm is the SCORE, which takes into account age, smoking habits, systolic blood pressure and total cholesterol (26). These parameters are introduced in a calculation tool that returns the 10-year risk of developing the first MACE. The same estimated risk rate can obviously be derived from different combinations and extent of the single risk factors and, as aforementioned, age has a heavy weight in the amount of risk, even when the other parameters are normal. For overcoming this overestimation, the concept of vascular age, based on the predicted CV risk, has been introduced. Vascular age of a subjects with a specific CV risk profile corresponds to the chronological age of a subjects who has the same estimated risk but only due to chronological age, because of the absence of the other modifiable risk factors (i.e., a non-smoker, normotensive and normocholesterolemic subject) (39,40). Vascular age carries the advantage of easily and directly communicating the concept of high relative risk to patients, in particular to younger ones, who are by definition at low absolute risk (“Your CV risk is the same of a man that is 15 years older than you”). Based on this interesting and useful concept of vascular age, we recently studied the clinical consequences of having a high discrepancy between the estimated vascular and the actual chronological age in our population of men consulting for ED. In our sample, a greater difference between vascular and chronological age was associated with higher glucose and triglyceride levels as well as with impaired penile colour Doppler ultrasound parameters, suggesting a CV impairment (41). When evaluating the subset of men for whom information on incident MACE during a mean follow-up of 4.3 years was available, a greater difference between vascular and chronological age was associated with the incidence of MACE in younger, but not in older men (42).

If on one hand, depression and anxiety can lead to ED, drugs commonly used for their treatment can cause ED, as well. Sexual dysfunctions are common side effects of several psychotropic drugs that can disrupt sexual health by several different mechanisms (83). In particular, ED has been reported in subjects using serotonin selective re-uptake inhibitors (SSRI), lithium and benzodiazepines (83). SSRI are associated with a broad spectrum of sexual dysfunctions, but the most commonly reported complaints are delayed ejaculation or anorgasmia and reduced sexual desire (84). Several mechanisms could be advocated including the agonist effect on serotonin receptors type 2 and the increase in PRL levels. ED is a frequent complaint as well (84,85). The relationship between the use of SSRI and ED can be secondary to loss of sexual desire but SSRI, in particular paroxetine, are also able to inhibit cholinergic receptors and nitric oxide synthase (86). In addition, it has been observed that SSRIs might down-regulate hypothalamic-pituitary-testis axis in depressed men (87).
This patient has thoroughly researched erectile dysfunction on the internet and has a powerful knowledge base from which he draws reference. He is also emotionally labile. The most urgent recommendation for this patient is that he seek appropriate psychiatric treatment to help in management of his psychiatric conditions and suicidal ideation. It was also recommended that he seek care with a sexual therapist to work through additional issues related to his “addiction” to masturbation. During his urologic visit we performed both cold and hot perception testing and biothesiometer, which were normal. He was displeased with these findings as they were incongruent with his chief complaints; normal results caused him to become tearful. A penile ultrasound was performed without injection of a pharmacologic agent to assess the appearance of his cavernous tissue and cavernous arteries, which had normal appearance and measurement, respectively, on ultrasound. (This quick bedside procedure has the potential to be both diagnostic and therapeutic for the patient; the importance of this cannot be underestimated).
The vacuum device creates a vacuum to pull blood into the penis. Unlike a normal erection, the inflow of blood does not continue once the individual removes the vacuum device. The rubber band placed at the base of the penis constricts the penis to prevent the blood from leaving the penis. As there is no inflow or outflow of blood when the rubber band is in place, it is uncommon for the tip of the penis (the glans) to appear a little blue and the penis to be cooler. Once intercourse is completed, the individual removes the rubber band and the blood drains out of the penis.
Penile prosthesis is a viable option for men who cannot use sildenafil and who find the injections or vacuum erection therapy distasteful. A non-adjustable semi-rigid prosthesis is easy to insert and has no postoperative mechanical problems. The inflatable prosthesis has a pump that is put in the testicular sac for on-demand inflation and deflation. Future versions will have a remote control device similar to a garage-door opener.

Malleable implants usually consist of paired rods, inserted surgically into each of the corpora cavernosa. The rods are stiff, and to have an erection, one bends them up and then when finished with intercourse one bends them down. They do not change in length or width. The malleable implants are the least mechanical and thus have the lowest risk of malfunction. However, also have the least "normal appearance."

All the above subjects were assessed for the prevalence of one or more sexual dysfunction experienced over the past 12 months using a sexual dysfunction checklist (Appendix A) by a trained psychiatrist (BSA). The checklist contains items corresponding to 12 areas of sexual dysfunction described in the Diagnostic Criteria for Research, ICD-10 Classification of Mental and Behavioural Disorders.[15] This was necessary as the SCAN does not contain a detailed assessment for the ICD-10 section on Sexual dysfunction not caused by organic disorder or disease (F52). The disorders specifically tapped by the checklist were aversion towards sex, low sexual desire, difficulty in achieving and in maintaining erection, premature ejaculation, inhibited or delayed ejaculation orgasm with flaccid penis, anorgasmia, pain at the time of coitus, dissatisfaction with frequency of intercourse per week (in the last year and in a representative week 5 years earlier), partner and, own sexual function.

Cognitive behavioral therapy (CBT) is a common and highly effective treatment for psychological issues in general, but also for ED. Facilitated by a therapist, this type of treatment helps you to identify and change unhealthy patterns of thought and action which may be contributing to your erectile issues. This kind of treatment is based on the idea that the situation itself (your inability to achieve or maintain an erection) is not the core problem, but rather your reaction to it. If you can learn to better understand yourself and your thought patterns, you can change them in a positive way to resolve your issues.

Although few studies specifically evaluated the clinical characteristics of ED in younger men, this problem is increasingly frequent. Healthcare professionals both inside and outside of Sexual Medicine are likely to deal with young men complaining for ED and it is important that basic knowledge on this topic is available. In fact, young men reporting ED risk being dismissed without any specific medical assessment, including medical history or physical exam, owing to the assumption that ED in younger is a self-limiting condition, without any clinical consequence. However, evidence shows that, similar to middle-aged or older men, ED can be the consequence of the combination of organic, psychological and relational factors and all these components must be assessed for a correct clinical management. In particular, ED in younger, even more than in older men, can be considered a harbinger of CVD and it offers the unique opportunity to unearth the presence of CV risk factors, thus allowing effective and high quality preventive interventions.
Also, even if rates of erectile difficulties are rising in young guys, we definitely can’t say why. While many like to point to increased access to online porn as the likely culprit, we need to be mindful of the fact that a ton of other things could potentially be playing a role. For example, young people today are much more likely to be using antidepressants than they were in the past, which we know can cause a number of sexual side effects. There may also have been changes in condom use patterns—we know that a lot of guys have erectile difficulties when using condoms, so if guys today are using more condoms, that could translate to more difficulties.
ED is easily and successfully treated! If your sex drive is unaffected, but you experience problems achieving or sustaining erection for a period of four to five weeks, you may have ED. Talk to your doctor immediately. Don’t delay—erectile dysfunction doesn’t “just go away!” Additionally, ED could be a sign of a serious, even life-threatening complication, such as congestive heart failure or kidney disease. Ignoring your ED because it’s embarrassing could jeopardize your health.
