What is Viagra?

Viagra is a brand name of the drug produced by pharmaceutical company Pfizer International Inc., and is the world’s first tool that is manufactured in the form of pill, having a large authentic effectiveness in millions of males. The unprecedented efficacy behind the Viagra lies in sildenafil citrate – the preparation’s active ingredient. The drug is manufactured in the form of 25, 50 and 100 mg pills.

How it works?

Understanding the nature of Viagra effect is hardly possible without knowing the mechanism of erection. Sexual stimulation contributes to an extension in blood vessels of small pelvis and increased rush of blood to the penis, so it becomes harder, and increases in size. After sexual arousal weakens, blood filling the penis decreases in quantity and the state of erection passes away. Taking certain medications (e.g., antihypertensive pills), and a number of chronic diseases impair vascular blood flow in the body, including arteries of the penis.

Sexual arousal does not lead to an increase in sufficient blood flow to the reproductive organ; and therefore an erection either doesn’t occur at all or becomes insufficient to initiate and sustain a full sexual intercourse. A repeated inability to have and maintain sexual intercourse during prolonged periods of time is referred to as erectile dysfunction. The phenomenon gathers a good number of of other manifestations, such as premature ejaculation, sexual fatigue and many more… and this is where Viagra comes to the rescue.

The preparation provides a selective effect that extends the vessels of the penis and leads to an increase in blood supply to the penis during sexual arousal, i.e. Viagra contributes to the emergence and maintenance of a normal erection. In addition to affecting the potency, Viagra improves more and sheer quality of sexual intercourse prolongs its duration, reduces the restoration and improves the emotional perception of orgasm.

The sexual status examination (SSE) is the most important assessment tool at the clin-ician’s disposal and is most evocative of the “review of systems” common to all aspects of medicine. A focused SSE critically assists in understanding and identifying the immediate cause of the ED (i.e., the actual behavior and/or cognition causing or contrib-uting to the sexual disorder). The clinician focuses on finding potential physical and specific psychosocial factors relating to the disorder. The clinician pursues a description of the sexual symptom and the history of the sexual symptom in detail. All patients assessed for sexual difficulties should be screened briefly for concurrent psychopathol-ogy. This does not need to be in-depth pursuit, unless there is evidence of a significant psychiatric disorder.

If you wonder if you are eligible for Viagra Australia online therapy, it is always a good call to go see your doctor first. It may be andrologist, urologist or family doctor. Even if your diagnosis proves to be erectile dysfunction, your prescriber will have to make sure that you have no contraindicating conditions and no pharmacological incompatibilities, as well as confirm that ED of your etymology is corrigible by the use of sildenafil citrate. Viagra should not be used recreationally under any conditions.

Information about the onset and progression of symptoms as well as a detailed descrip-tion of the patient’s sexual symptom should be obtained. The physical and emotional cir-cumstances surrounding the onset of a difficulty are important for the assessment of both physical and psychological causes. If these details are not spontaneously offered, the clinician must elicit them. By juxtaposing detailed questions about the patient’s current sexual practices and history, an understanding of the causes of dysfunction and noncom-pliance can be unveiled.

A detailed analysis of the patient’s current sexual behavior and the couple’s erotic inter-action can help eliminate potential organic causes. Additionally, the sexual information evoked in SSEs helps anticipate noncompliance with medical and surgical interventions. Modifying immediate psychological factors may result in the need for less medication  Generally, urologists and PCPs intervene with pharmacotherapy and brief sexual coach-ing, which address immediate causes (e.g., insufficient stimulation) directly and inter-mediate issues (e.g., partner issues) indirectly and are rarely focused on deeper issues (e.g., sex abuse). In fact, a referral is usually appropriate when deeper psychosocial issues are primary.

Early in the SSE, a physician should obtain a description of a recent experience that incorporates the sexual symptom. One question helps elucidate many of the immediate and remote causes: “Tell me about your last sexual experience.” The clinician can quickly identify common immediate causes of ED from the patient’s response. Several frequently identified contributors to ED include insufficient stimulation (e.g., a lack of adequate friction), a lack of subjective feelings of arousal, fatigue, and negative thinking. Sex is fantasy and friction, mediated by frequency. To function sexually, men need sexy thoughts and not just adequate friction. Although fatigue is a common cause of sexual dys-function in our society, negative thinking/anti-fantasy is also a significant contributor.
