In rare cases, the drug Viagra ® can cause blue-green shading to vision that lasts for a short time. In rare cases, the drug Cialis® can cause or increase back pain or aching muscles in the back. In most cases, the side effects are linked to PDE5 inhibitor effects on other tissues in the body, meaning they are working to increase blood flow to your penis and at the same time impacting other vascular tissues in your body. These are not ‘allergic reactions'.
You may find that using a vacuum device requires some practice or adjustment. Using the device may make your penis feel cold or numb and have a purple color. You also may have bruising on your penis. However, the bruises are most often painless and disappear in a few days. Vacuum devices may weaken ejaculation but, in most cases, the devices do not affect the pleasure of climax, or orgasm.
Performance anxiety can be another cause of impotence. If a person wasn’t able to achieve an erection in the past, he may fear he won’t be able to achieve an erection in the future. A person may also find he can’t achieve an erection with a certain partner. Someone with ED related to performance anxiety may be able to have full erections when masturbating or when sleeping, yet he isn’t able to maintain an erection during intercourse.
As you can imagine, these symptoms can make it difficult to take pleasure in much of anything, let alone sex. A study published in a 1998 edition of Psychosomatic Medicine shows a clear link between depression and erectile dysfunction in men. Using data obtained from the Massachusetts Male Aging Study, researchers were able to conclude that a relationship between depressive symptoms and erectile dysfunction existed and was independent of aging and demographics.
Ageing is one of the most important unmodifiable risk factors for the development of metabolic disorders and CV diseases. Accordingly, the common algorithms for the estimation of risk of forthcoming diabetes or CV events include age as a factor of the equations (24-29). The weight attributed to age for estimating the risk in these equations is often so significant that younger men are automatically considered at low risk, irrespective of the other possible risk factors. However, even in younger subjects, overlooking the contribution of cardio-metabolic factors to pathogenesis of ED is a mistake that can lead to the loss of the opportunity of early recognition of patients who deserve a change in life-style or a pharmacological correction of risk factors. ED, besides being considered one of the clinical manifestations of metabolic and cardiovascular diseases (CVD), is regarded as an early marker of CV events (17). In fact, according to Montorsi’s hypothesis (30), impairment of penile artery blood flow occurs before that of coronary or carotid arteries, whose diameter is greater and needs longer time to acquire a clinically relevant damage. The clinical consequence of this pathological event is that ED often manifests earlier than myocardial infarction or stroke. In particular, it has been demonstrated that ED occurs on average three years before the first major adverse CV event (MACE) (31). Quite surprisingly, although CV risk increases with ageing, the role of ED as a harbinger of forthcoming MACE becomes progressively less evident. Data derived from almost 2,500 community-dwelling men aged 40–79 years, involved in the Olmsted County study show that ED is associated with an almost 50-fold higher risk of incident heart diseases in men aged 40–49 years, whereas the difference in risk between ED and non-ED men progressively declines in older men (32). The different CV risk associated with ED in different age bands has been confirmed by the meta-analysis of the available longitudinal studies (33). These observations suggest that, in younger men, the role of ED as a marker of CV risk is even more dramatic than in older ones and as a consequence, investigating the presence of metabolic or CV conditions in younger ED patients is pivotal for identifying men in whom an early life-style modification may avoid serious CV consequences. Even more than erection during sexual intercourse, erection during masturbation is considered a physiologic function that mirrors metabolic and CV health. In fact, erections during masturbation are far less affected by relational and psychological components than sex-related ones (34). In a population of subjects attending the Sexual Medicine and Andrology Unit of the University of Florence for sexual dysfunction, more than 2,500 men reported autoeroticism in the previous 3 months. Among these men, the impairment of erection during masturbation was associated with family and personal history of CVD (35), as well as with impaired response to the test with the intracavernous injection (ICI) of prostaglandin E1, which suggests an arteriogenic damage of penile arteries and predicts forthcoming MACE (36). For a subset of these men (n=862), information on the occurrence of MACE during a mean follow-up of 4.3 years was available and those who reported impaired erections during masturbation had a significantly higher incidence of MACE (35). However, when considering separately younger and older men, this association was confirmed only in younger ones, and it was still significant after excluding men reporting severe ED during masturbation (35). This suggests that the impairment of erection during masturbation is a symptom not completely overlapping with sex-related ED and that it can provide different and supplementary information, in particular when assessed in younger and apparently healthy men. Similarly to what is observed for erection during masturbation, acceleration of blood in penile arteries, as measured by the colour Doppler ultrasound in flaccid conditions, is associated with an adverse CV profile in men consulting for ED. A reduction in flaccid acceleration, which can be used by clinicians to objectively verify the arteriogenic origin of ED and to characterize the extent of a self-reported symptom, has been also associated with a future risk of CV events, with the association being significant in younger but not in older men (37).
Erections also require neural input to redirect blood flow into the corpora cavernosae. Psychogenic erections secondary to sexual images or auditory stimuli relay sensual input to the spinal cord at T-11 to L-2. Neural impulses flow to the pelvic vascular bed, redirecting blood flow into the corpora cavernosae. Reflex erections secondary to tactile stimulus to the penis or genital area activate a reflex arc with sacral roots at S2 to S4. Nocturnal erections occur during rapid-eye-movement (REM) sleep and occur 3–4 times nightly. Depressed men rarely experience REM sleep and therefore do not have nocturnal or early-morning erections.
"Smoking is a short- and long-term cause of erectile dysfunction," warns Feloney. "In the short-term nicotine constricts the blood vessels that you need to get an erection, and in the long-term nicotine contributes to hardening of the arteries that can cause erectile dysfunction." Some approaches for quitting include making a clean break, avoiding the triggers of smoking, trying a nicotine patch or gum, and joining a smoke cessation program.
Alcohol is a depressant, not an aphrodisiac or a libido enhancer. Excessive consumption can interfere with the ability to achieve an erection at any age, and even occasional drinking can make erectile dysfunction worse in older men. Feloney advises using alcohol in moderation: "In small amounts, alcohol can relieve anxiety and may help with erectile dysfunction, but if you drink too much, it can cause erectile dysfunction or make the problem worse."
Erectile dysfunction is a common occurrence in men with diabetes. The incidence of erectile dysfunction increases progressively with age, from 5% in men age 20 to 75% in men over age 65. The cause of erectile dysfunction in men with diabetes is usually related to a decrease in the blood supply to the penis as well as to injury to the nerves that are responsible for the erection mechanism. A decrease in testosterone production has also been identified as the cause in some men with diabetes.
Sexuality and erection are controlled by multiple areas of the human brain including the hypothalamus, the limbic system, and the cerebral cortex. Stimulatory or inhibitory messages are relayed to the spinal erection centers to facilitate or inhibit erection (5). Two mechanisms have been proposed to explain the inhibition of erection in psychogenic dysfunction: direct inhibition of the spinal erection center by the brain as an exaggeration of the normal suprasacral inhibition and excessive sympathetic outflow or elevated peripheral catecholamine levels, which may increase penile smooth muscle tone and prevent the relaxation necessary for erection (8). Animal studies demonstrate that the stimulation of sympathetic nerves or systemic infusion of epinephrine causes detumescence of the erect penis (6,7). Clinically, higher levels of serum norepinephrine have been reported in patients with psychogenic ED than in normal controls or patients with vasculogenic ED (9).
The bottom line is that nearly all men with diabetes who wish to have an erection adequate for sexual intercourse can do so with the therapies currently available. And with commitment and communication, the experience of erectile dysfunction can be changed from a potential personal tragedy to an opportunity for greater emotional intimacy in a couple.
All of these medicines work by relaxing smooth muscles and increasing blood flow in the penis during sexual stimulation. You should not take any of these medicines to treat ED if you are taking nitrates to treat a heart condition. Nitrates widen and relax your blood vessels. The combination can lead to a sudden drop in blood pressure, which may cause you to become faint or dizzy, or fall, leading to possible injuries.
Erectile dysfunction, also known as ED or impotence, is the inability to attain or maintain an erection of the penis adequate for the sexual satisfaction of both partners. It can be devastating to the self-esteem of a man and of his partner. As many as 30 million American men are afflicted on a continuing basis, and transient episodes affect nearly all adult males. But nearly all men who seek treatment find some measure of relief.
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."

If you are taking medications (alpha-blockers) for problems with an enlarged prostate, you should discuss your prostate medications with your doctor. Alpha-blockers also can cause lowering of the blood pressure. Thus your doctor will need to carefully watch your blood pressure when you start the PDE5 inhibitor. Common alpha-blockers include doxazosin (Cardura), terazosin (Hytrin), and tamsulosin (Flomax).
Oral medicines: The best known ED medications are the Big Three: Viagra (sildenafil citrate, made by Pfizer, Inc.), Levitra (vardenafil HCl, made by Bayer and GlaxoSmithKline), and Cialis (tadalafil, made by Eli Lilly). The three are chemically very similar, and all have proven very effective. Because they are effective, convenient, and relatively inexpensive (about nine dollars per pill), these medicines have become the treatment of choice for most men experiencing ED.
