Viagra Can Make Fantasies into Realities

Men who suffer from erectile dysfunction often think that a normal sex life is something that is beyond their reach. The idea of having a satisfying intimate relationship with their spouse or partner has become a fantasy. However, there is hope for turning that fantasy back into a reality with Viagra. Viagra can bring back the fun in the bedroom of many men who thought that their sex life was over permanently. If you have found that your sex life has turned into nothing but a fantasy since you began having problems with erectile dysfunction, Viagra may be right for you.

Why Do You Need Viagra?

While in an ideal world, erectile dysfunction would be a temporary problem that would clear up on its own within a few weeks, or months, at the most, the majority of men need Viagra or some other medical assistance to overcome the symptoms. Many times erectile dysfunction cannot be cured, only treated with Viagra whenever sexual activity is desired. If you are suffering from erectile dysfunction, you can get back your sex life by using Viagra.

What Does Viagra Do?

Many people believe that Viagra Professional Canada is a sexual stimulant or causes an erection, just from taking the pill itself. This common belief is actually a myth. Viagra works by helping to reestablish blood flow to the penis. This will allow you to achieve and maintain an erection, just as you naturally would. Viagra does not cause an erection by itself; it just allows you to react as you normally do to sexual stimulation. With Viagra, the process that it takes to get an erection does not change; it is just aided and enhanced by taking the medication.

What Are The Benefits?

Of course, the main benefit of Viagra is the reason you would choose to try it in the first place. Viagra works within the body to allow users to achieve an erection and to keep it throughout the act of sex. You and your partner can get greater satisfaction when you are intimate, allowing for a more enjoyable experience for you both. Outside the newfound enjoyment of your intimate, physical relationship, other aspects of your relationship will improve greatly, as well. You will likely have a closer relationship emotionally, too, as a result of Viagra. If your self-image or self-esteem was affected by your inability to perform in the bedroom, that will also quickly correct itself. So many aspects of your life can be positively affected by trying Viagra, it can really turn your world into the existence of your dreams.

What Are The Cautions?

While Viagra is very safe for most men to take, there are a few red flags that everyone considering Viagra should be aware of. Those with serious heart conditions and other medical situations that keep them from safely participating in sex should not take Viagra. This includes those who have been recently treated for stroke and heart attacks. If you are on medications such as alpha-blockers to control your blood pressure, you may not be able to take Viagra Online in New Zealand. The most dangerous drug interaction that has been shown in studies is that of nitrates and Viagra. Anyone who uses nitrates in any form should not take Viagra. Failure to heed this warning could prove to be fatal. Even with these extreme warnings about interactions, if care is taken when obtaining Viagra, it is an effective and safe treatment for erectile dysfunction.

How Can You Get Viagra?

Obtaining a prescription for Viagra is as simple as making an appointment with your doctor. As long as you are healthy enough for sex and are not taking any conflicting medications, you should be able to try Viagra without any problems or difficulties. Your doctor will evaluate your physical health and look at your current medications to decide if taking Viagra is a safe choice for you. Once you have been given the green light and a prescription, simply fill it at the pharmacy of your choice and you are good to go. The fantasy of getting back your intimate relationship with your partner can again become a reality once you get your prescription for Viagra.

How Sildenafil Citrate Works

Sildenafil citrate facilitates erections in men with psychogenic diabetic, vasculogenic, traumatic, and surgical causes of erectile dysfunction. It is not an “orgasm pill/* does not increase desire, and does not facilitate erection in the absence of psychological or tactile stimulation. Nevertheless, all these factors are interrelated; indirect effects are probably observed. Simplistically, erection is the process of sequestering blood within the penis to increase its size and rigidity. Tactile or psychological stimuli, or both, can initiate or sustain the process.

The blood is predominantly sequestered in the corpora cavernosa, two connected spongelike bodies in the penile shaft. The corpora cavernosa comprise a network of arteries, veins, nerves, smooth muscles, and sinuoids (i.e., the spaces that actually fill with blood). The tunica albuginea is a thick, fibrous bilaycr sheath that surrounds the corpora cavernosa. As the corpora cavernosa fill with blood, the tunica albuginea stretches to its capacity. The veins that drain the corpora cavernosa are compressed against and between the layers of the tunica albuginea, preventing outflow. The bulbocavernous muscles at the base of the penis contract, which raises the pressure above systemic blood pressure and results in a rigid penis.

The lining of the corpora cavernosa and some penile nerves produce nitric oxide (NO). The NO induces the production of cyclic guanosine monophosphate (cGMP), which specifically causes penile smooth muscle relaxation. In a process that is still not completely understood, smooth muscle relaxation leads to the trapping of blood in the corpora cavernosa. The NO also causes the arterioles (small arteries) to dilate, increasing the blood flow into the corpora cavernosa. The cGMP is degraded by phosphodiesterase type 5 (PDE5), an enzyme predominantly found in the penis. When the cGMP is degraded, the smooth muscle returns to its resting (contracted) state, the outflow of blood increases, and the erection re¬solves.

Sildenafil inhibits the action of PDE5, allowing smaller amounts of cGMP to produce an erection and for that erection to last longer. Similarly, less NO is needed to produce an equivalent amount of cGMP.

Sildenafil has been approved only for use in men; research on its effects in women is ongoing. Preliminary results are conflicting. Initial investigations reported that Sildenafil increased lubrication, genital sensation, ability to achieve orgasm, and sexual satisfaction among women with complaints of sexual dysfunction. Application of topical Sildenafil was reported to improve arousal, genital sensation, and ability to reach orgasm in a small sample of women with sexual dysfunction. Others, however, have found little evidence thus far that sildenafil is useful in the treatment of sexual dysfunction in women. Kaplan, Reis, Kohn. Ikeguchi, Laor, Те, and Martins, for example, concluded, “Our data do not support the use of sildenafil in treat¬ing postmenopausal women with sexual dysfunction.” Its effects and uses for women remain to be fully elucidated. In addition, sildenafil for women carries the same risks of misuse as for males.

Feminist Sex Therapy in the Age of Viagra™

Pharmacological treatments of sexual dysfunction have opened a new and exciting area for clinical sexology and sex therapy. Used correctly they can help people to overcome fears of and actual sexual dysfunction. Used incorrectly, they can wreak havoc in the relationship or with the individual. The recent pharmaceutical debut of sildenafil citrate (Viagra™), and the ensuing stampede by male consumers to obtain it, is a significant historical moment in our collective sexual history. The advent of a medication that reduces the vulnerability of erections to some psychological and even medical causes of impairment provides many men with a “bionic” insurance policy against shame regarding their sexual performance.

Undoubtedly, many men and their partners are well-served by sildenafil citrate. Such couples are unequivocally delighted at the remission of erectile problems, enjoying their regained ability to lose themselves in the sexual encounter without worrying about erections. For other couples, sildenafil citrate uncovers relational dilemmas, revealing the inadequacy of the medicalized construction of sexuality. The impact of any new medical innovation that makes it easier for men to have erections and thus to have penetrative sex must be understood within the relational and social context.

Fueled by the media and the anonymity and accessibility of the Internet, millions of patients are requesting pharmacological solutions for erectile dysfunction. Clearly, not all individuals who would benefit from sildenafil citrate are availing themselves of it; conversely, many inappropriate prescriptions have been written. Our clients and the public in general will not be well-served if sildenafil citrate is used indiscriminately. Any intervention, including psychotherapy, can be misused or abused. Pharmacotherapy is no different. Sildenafil citrate is just the first in a series of drugs that will treat various sexual concerns. Sex therapists should familiarize themselves with the uses, abuses, and misuses of these drugs. Some patients will seek out a nonphysical to avoid confronting a physical defect or problem. The opposite is also true—patients who want to deny a psychogenic etiology of their dysfunction will present to a physician. The solution to this dilemma involves helping both sex therapists and physi­cians to incorporate these new medications in social and relational con­text.

Feminist Sex Therapy

Feminist sex therapy has led the field in recognition of the costs of dismembering of sexuality from relational context. Tiefer identified the influences of the positivist approach and of biologically based explanations of human sexuality in the misdirection of sex therapy’s focus away from sex-role, relational, or psychological issues. Seidler-Feller ques-tioned the adequacy of sex therapy from a feminist perspective, citing the tendency to implicitly reinforce normative sex roles and the power differential between the sexes that underlies them. Tiefer also critiqued the DSM-III sexual dysfunction nomenclature as focusing exclusively on physical performance while omitting empirically based information on what women consider important in sexual life, including intimacy, negotiation, and communication. Tiefer adapted Reissman’s analysis regarding the negative consequences of medicalization for women’s sexuality, pointing out the processes of mystification, moral neutrality, and individualization of sexual problems inherent in the medicalized, traditional approach.

Mystification places definitions of “normal and healthy” sexual functioning in the hands of officially sanctioned experts rather than selfdefined enjoyment, more often reflecting these experts’ reality rather than women’s. When medical science alone defines the norms for sex, an objective reality is assumed, leading to a stance of moral neutrality in which “sex is no longer a human arena for negotiation, but an arena where there is an objective standard against which performance can be measured”. McCormick further identified the “nonconscious equation of sexual activity with reproductive potential” that influences clinicians to equate sexual dysfunction with “physical failures in the performance of intercourse”. In indhidualizniii sexuality and sexual problems, medicalization denies and obscures the effects of social contri-butions to people’s sexual complaints, including rigid sex roles, unrelenting standards of performance, relationships of unequal power, and histories of sexual victimization.

Tiefer recommended that feminist sex therapy include “corrective genital physiology education, assertiveness training, body image reclamation, and masturbation education.” McCormick also recommended that therapists treat individuals and couples for deficits in tenderness, poor communication, sexual selfishness, disinterest in oral sex, and unwillingness to cuddle, although she noted that deficits in these areas have not been assigned formal psychiatric diagnoses. A feminist approach to sex therapy uses existing scientific knowledge about biology, medical approaches, and empirically validated treatment techniques while adding the following ingredients:

  1. Recognition of social and cultural gender inequality;
  2. Recognition of the influence of this power differential in relationships, and a willingness to intervene at this level;
  3. Valuing equally the subjective and affective aspects of sexuality, relative to physical performance;
  4. Recognition of traditional sex roles as etiologic of many sexual problems, and a willingness to intervene at this level; and
  5. Recognition of the unique experiences of men and women regarding sexual socialization, experiences of sexual coercion, sexual decision making, and the influence of relational factors in sexual dysfunction.

Endocrine Causes Part 2

Evaluation for low testosterone involves a simple blood test. If low testosterone is diagnosed in a man with some of the aforementioned symptoms, consideration for testosterone replacement therapy is in order. The goal is to restore testosterone to normal levels and to treat the symptoms and signs of low testosterone with better libido and erectile function and improved energy, body composition (reduced fat, increased muscle) and increased bone mineral density. There are a variety of different means of testosterone replacement therapy (TRT). Oral replacement is not used because of erratic absorption and liver toxicity.

Injections are generally not the first-line means of TRT because of wide fluctuations in testosterone levels and injection site reactions. There are a number of gel formulations that are commonly prescribed including: Androgel; Testim; Axiron; Fortesta; additionally, many pharmacies will compound testosterone in gel or cream formulation at a fraction of the cost of the commercially available products. With the gels and creams, one needs to beware of skin-to-skin contact with the potential exposure of testosterone to others. There are scrotal patches: Testoderm and non-scrotal patches: Androderm, both of which can cause skin irritation. There is another formulation in the form of pellets that are injected into the fatty tissue of the buttocks: Testopel, advantageous in terms of its long-term efficacy (3-6 months) but disadvantageous in terms of the need for the minor procedure for implantation. There is a buccal formulation that is placed in the inner cheek or gum: Striant, a simple means of administration, but one that can cause gingivitis, interference with eating, drinking and dental hygiene.

Men on TRT need to be carefully followed to ensure that the testosterone is effective, adverse effects are minimal, and blood levels are in-range. Periodic digital rectal exams are important to check the prostate and in addition to testosterone levels, other blood tests are obtained including a complete blood count and PSA. Side effects of TRT may include the following:

  • Oily skin; acne
  • Sleep apnea
  • Breast growth
  • Increased red blood cell count
  • Lipid profile changes
  • Infertility—testosterone can be viewed as a male contraceptive
  • Testes atrophy

Endocrine Causes Part 1

Testosterone (T) is an important male sexual hormone that promotes the physical changes that commence at the time of puberty including pubic, axillary and facial hair, deepening voice, prominent Adam’s apple and increased bone and muscle mass. Throughout adulthood, testosterone helps maintain libido, masculinity, sexuality, and youthful vigor and vitality.

The lion’s share of testosterone is manufactured in the testicles, although a small percentage is made by the adrenal glands. Healthy men produce 6-8 mg testosterone/day in circadian pattern with a peak in early morning hours and lag in the late afternoon. There is a gradual decline in T that occurs with the aging process—approximately a 1% decrease each year after age 30. The decline will occur in most men, but will not always be symptomatic. Symptoms of low T may include one or more of the following: fatigue, irritability, depression, decreased libido, erectile dysfunction, ejaculatory dysfunction, decreased energy and sense of wellbeing, loss of muscle and bone mass, increased body fat, abnormal lipid profiles. Essentially, low T can accelerate the aging process.

There is a strong relationship between low T and Metabolic Syndrome. Metabolic Syndrome is defined as having three or more of the following: high blood glucose levels; abdominal obesity; high fats (triglycerides); low levels of the “good” cholesterol (HDL); and high blood pressure.

Obesity can have a pivotal role in the process leading to low T. Fat is not just fat—it is a metabolically active endocrine organ that does not just protrude from our abdomens in an inert state. Fat produces pro-inflammatory factors, hormones and immune cells—including cytokines—which function to inhibit T production in the testicles and the release of hypothalamus and pituitary hormones that govern the release of T. Low T is present in about half of obese men. Fat has an abundance of the hormone aromatase, which functions to convert T to the female hormone estrogen (E). The consequence of too much conversion of T to E is the potential for gynecomastia, aka breast enlargement.

ED: Vascular Causes, Neurologic Causes

An erection requires a substantial increase in penile blood flow. If the cavernosal arteries (the arteries to the corpora cavernosa) are unable to increase the blood flow to the penis, vascular E.D. will occur.

If a person has generalized atherosclerosis (fatty deposits narrowing the caliber of their arteries) as evidenced by angina, heart attacks, strokes, and/or claudication (leg and buttock pain that occurs with exercise and is indicative of poor blood flow), there is a great likelihood of penile arterial involvement as well. Diabetes, for example, is well known to give rise to atherosclerosis. Radiation therapy to the pelvis can cause scarring and damage to the penile circulation, thus resulting in vascular E.D. Because cigarettes contain nicotine (which functions to constrict blood vessels), E.D. commonly occurs on the basis of chronic cigarette use.

In many men, the arterial supply to the penis is intact, but because of venous leakage (a condition in which the otherwise rigid corpora cavernosa soften prematurely due to loss of blood through the veins), an erection cannot be sustained for long. The blood flow simply drains away from the corpora, resulting in flaccidity of the penis and the inability to maintain an erection. This is the underlying cause in about 70% of patients who suffer from ED. It is due to the loss of corporal smooth muscle such that sufficient relaxation to achieve obstruction of venous outflow cannot occur. The blood in the sinusoids leaks back into the venous system draining the penis. It is similar to essential hypertension, which is due to the loss of smooth muscle within the arterial walls that leads to stiff vessels in which relaxation is impaired.

Normal erectile function requires an intact brain, spinal cord, and peripheral nerve supply to the corpora cavernosa. Any interruption of the nervous system may result in E.D. since it is the nerve impulse to the cavernosal arteries that is the trigger for increased penile blood flow.  Generic Viagra Mexico

Diabetes, besides causing damage to penile circulation, causes a penile neuropathy (nerve damage) that commonly results in E.D. Alcohol abuse similarly may give rise to a neuropathy accounting for E.D. In fact, any neurological disease process (including multiple sclerosis, Parkinson’s disease, spina bifida, etc.) may result in E.D. Injury or trauma to the brain, spinal cord, or pelvis may cause E.D. on a neurogenic basis. A pelvic fracture may injure the nerve supply to the corpora cavernosa. Radiation therapy, besides causing damage to penile circulation, can damage the cavernosal nerve supply. Radical pelvic surgery (most commonly for bladder, prostate, or rectal cancers) may require removal of the cavernosal nerve supply, resulting in E.D.
