Prices of Viagra and Cialis

Erectile dysfunction (ED) affects the lives of many middle-aged men and their partners. The term erectile dysfunction covers a range of disorders, but usually refers to the inability to obtain an adequate erection for satisfactory sexual activity. Although erectile dysfunction, formerly called impotence, is more common in men older than 65, it can occur at any age. An occasional episode of erectile dysfunction happens to most men and is normal. As men age, it's also normal to experience changes in erectile function. Erections may take longer to develop, may not be as rigid or may require more direct stimulation to be achieved. Men may also notice that orgasms are less intense, the volume of ejaculate is reduced and recovery time increases between erections. Erectile dysfunction may also be a sign of a physical or emotional problem that requires treatment.

Erectile dysfunction was once a taboo subject, but more men are seeking help. Doctors are gaining a better understanding of what causes erectile dysfunction and are finding new and better treatments.

This Website discusses all about erectile dysfunction, physiology of the normal erection and the pathophysiology, and treatment of ED.

What is Erectile Dysfunction?

Erectile dysfunction or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis for satisfactory sexual intercourse regardless of the capability of ejaculation. There are various underlying causes, such as diabetes, many of which are medically reversible.

The causes may be physiological or psychological viagra price comparison. Psychological impotence can often be helped by almost anything that the patient believes in; there is a very strong placebo effect.

Due to its embarrassing nature and the shame felt by sufferers, the subject was taboo for a long time, and is the subject of many urban legends. Folk remedies have long been advocated, with some being advertised widely since the 1930s. The introduction of perhaps the first pharmacologically effective remedy for impotence, sildenafil (trade name Viagra), in the 1990s caused a wave of public attention, propelled in part by the news-worthiness of stories about it and heavy advertising.

The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms.

Signs and symptoms:

Erectile dysfunction is characterized by the inability to maintain erection. Normal erections during sleep and in the early morning suggest a psychogenic cause, while loss of these erections may signify underlying disease, often cardiovascular in origin. Other things leading to erectile dysfunction are diabetes mellitus (causing neuropathy) or hypogonadism (decreased testosterone levels due to disease affecting the testicles or the pituitary gland).

Here are some causes of Erectile Dysfunction:

* Arousal: The first step is sexual arousal, which men obtain from the senses of sight, touch, hearing and smell, and from thoughts about viagra price comparison.

* Nervous system response: The brain communicates the sexual excitation to the body's nervous system, which activates increased blood flow to the penis.

* Blood vessel response:. A relaxing action occurs in the blood vessels that supply the penis, allowing more blood to flow into the shafts that produce the erection.

Physiology of normal erections:

Penile erections involve an integration of complex physiologic processes involving the CNS, peripheral nervous system, and hormonal and vascular systems. Any abnormality involving these systems, whether from medication or disease, has a significant impact on the ability to develop and sustain an erection, ejaculate, and experience orgasm. Tumescence, the vascular filling of the cavernous bodies, relies on neural and hormonal mechanisms operating at various levels of the neural axis. This is unique among visceral functions because it requires central neurological input.

Andersson et al viagra price comparison summarized some of the information related to the pathways involved in erectile function. The degree of contraction of corpus cavernosal smooth muscle determines the functional state of the penis. The balance between contraction and relaxation is controlled by central and peripheral factors that involve many transmitters and transmitter systems. At the cellular level, smooth muscle relaxation occurs following the release of acetylcholine from the parasympathetic nerves.

Pathophysiology of erectile dysfunction:

Erectile Dysfunction is essentially a vascular disease. It is often associated with other vascular diseases and viagra price comparison conditions such as diabetes, hypertension, and coronary artery disease. Other conditions associated with Erectile Dysfunction include neurologic disorders, endocrinopathies, benign prostatic hyperplasia, viagra price comparison, and depression. Conditions associated with reduced nerve and endothelium function, such as aging, hypertension, smoking, hypercholesterolemia, and diabetes, alter the balance between contraction and relaxation factors. These conditions cause circulatory and structural changes in penile tissues, resulting in arterial insufficiency and defective smooth muscle relaxation. In some patients, sexual dysfunction may be the presenting symptom of these disorders.

Treatment:

Sildenafil Citrate is the way to treat Erectile Dysfunction. Generic Viagra contains sildenafil citrate and contains same ingredients like branded drug.

What is Premature Ejaculation?

Among a number of problems related with the sexual health of men and of course his partner, we find Premature Ejaculation as the most common sexual problem , this is a pathology characterized by a lack of voluntary control over ejaculation. Masters and Johnson stated that a man suffers from premature ejaculation if he ejaculates before his partner achieves orgasm in more than fifty percent of his sexual encounters. Other sex researchers have defined premature ejaculation as occurring if the man ejaculates within two minutes of penetration; however, a survey by Alfred Kinsey, (yes the inquisitive scientist of the movie the recently showed in theaters) made in the 1950s demonstrated that three quarters of men ejaculated within two minutes of penetration in over half of their sexual encounters. Today, most sex therapists understand premature ejaculation as occurring when a lack of ejaculatory control interferes with sexual or emotional well-being in one or both partners. An estimated thirty percent of men suffer from premature ejaculation on a consistent basis.

Premature Ejaculation is believed to be a psychological problem and does not represent any known organic disease involving the male reproductive tract or any known lesions in the brain or nervous system. In short, PE is not a physiological problem or disease, though it manifests physiologically by considering the organ systems directly affected by PE, that include the male reproductive tract (ie, penis, prostate, seminal vesicles, testicles, and their appendages), the portions of the central and peripheral nervous system controlling the male reproductive tract, and the reproductive organ systems of the sexual partner (for the purpose of this discussion, the partner is assumed to be female) that may not be stimulated sufficiently to achieve orgasm. If the PE occurs so early that it happens before commencement of sexual intercourse and the couple is attempting pregnancy, then pregnancy is impossible to achieve unless artificial insemination is used. Perhaps the most affected organ system is the psyche of the partners. Both partners are likely to be dissatisfied emotionally and physically by this problem.

Frequency:

In the US: The prevalence rate of PE in American males is estimated to range from 30-70%.

Internationally: Estimates for European countries and India mirror the prevalence in the United States. The prevalence in other parts of Asia, Africa, Australia, and elsewhere is unknown. Mortality/Morbidity: No known direct morbidity or mortality results from PE.

Race: No reproducible data exist on major differences between racial groups with respect to the incidence or prevalence of PE.

Sex: PE is a condition that only affects males.

Age: PE can occur at virtually any age in an adult man's life. It is most common in younger men (aged 18-30 y), but it also may occur in conjunction with secondary impotence in men aged 45-65 years.

If you or someone near you suffers from Premature Ejaculation problems you should know that this is a curable condition. You can learn more at this site: http://www.askingplanet.com
