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.

Men and Sperm Health

Men - What You Do On A Daily Basis Affects Your Sperm Maturation Process

While a woman is born with all the eggs she'll ever have, men produce sperm on a continual basis. Therefore, what a man does on a daily basis can affect the sperm maturation process.

Smoking, drinking, drugs, stress, poor nutrition and lack of exercise all can contribute to poor sperm quality. And, it was recently discovered, a man's sperm quality begins to decline around the age of 25.

There are five main factors that contribute to overall sperm quality. They include sperm motility, speed, count, concentration and morphology (shape and size).

A weakness in any of these areas can affect the chances of conception.

Motility

Sperm motility is a term that describes sperm's ability to move in an active fashion: in other words, are the sperm "strong swimmers?" In healthy sperm, typically more than 50% are active with over 25% moving forcefully in one direction. Motility enables the sperm to travel through the cervical canal, into the uterus and the fallopian tubes and, finally, to penetrate the egg.

Speed

The forward movement of sperm called progressive motility, forward progression or rapid linear progression. There are also several different ways to classify forward movement.

According to the World Health Organization (1999), in a healthy male, greater than 25% of sperm will exhibit progressive motility. It is thought that these are the sperm with the best chance of successfully fertilizing an egg.

Rapid linear progression showed a greater than 60 % improvement after four months of treatment with acupuncture, herbal medicine and supplements.

Sperm Count

Sperm count refers to the number of sperm in the fluid that is ejaculated (semen). There are over 40 million sperm in a normal ejaculate. A total count below 40 million may indicate decreased fertility.

With the Berkley Center's unique protocol of acupuncture, herbal medicine and supplements, count increased more than 14 % after four months of treatment.

Concentration

Concentration is a measure of the number of sperm cells in a milliliter of semen. Normal concentration is at least 20 million sperm cells per milliliter of semen.

With the Berkley Center's unique protocol combining acupuncture, herbal medicine and the appropriate supplements, concentration improved after four months of treatment.

Morphology (shape and size)

A healthy sperm cell will have a shape similar to a tadpole. The sperm's oval head contains the genetic material, the center provides energy and the tail propels the sperm forward.

Using the strict criteria put forth by the World Health Organization (1999), studies of Assisted Reproductive Technology programs show lower pregnancy rates with less than 15% normal forms. Furthermore, experts believe that abnormally shaped sperm cannot fertilize an egg.

Subfertility

The term, subfertility, refers to couples that are unable to achieve conception after a year of unprotected intercourse (or 6 months if the woman is over age 35). It is different from infertility. A subfertile couple merely has lower odds of conceiving during any given month than fertile couples.

Statistics at a glance

  • Human reproduction is surprisingly inefficient and quite complex -- the likelihood of pregnancy within any given month is believed to be only 25 percent among fertile couples.

  • 1 out of 12 couples have subfertility.

  • Male-related factors account for 40 percent of subfertility. Female-related factors account for another 40 percent and a combination of male- and female-related factors account for about 20 percent.

  • About 90% of all subfertility can be traced to specific causes that can be treated.

Typical causes of male subfertility

  • Sperm production problems

  • Blockages in the sperm's delivery system

  • Injuries to the testicles

  • Low or high hormone production

  • Anatomical problems

  • Varicocele (varicose veins around the testicle)

  • Past illnesses/infections/various diseases

  • Certain medications

Sperm quality

Sperm quality is a contributing factor for 40 percent of couples experiencing infertility. There are five main factors that contribute to sperm quality:

  • Motility: The ability to move in an active fashion. In healthy sperm, typically more than 50% are active with over 25% moving forcefully in one direction. Motility is what enables a sperm to travel up the cervical canal, into the uterus and the fallopian tubes and, finally, penetrate the egg.

  • Speed: Progressive motility. In a healthy male, greater than 25% of sperm will exhibit progressive motility. It is thought that these are the sperm with the best chance of successfully fertilizing an egg.

  • Count: The number of sperm in the fluid that is ejaculated (semen). There are over 40 million sperm in a normal ejaculate. A total count below 40 million may indicate decreased fertility.

  • Concentration: A measure of the number of sperm cells in a milliliter of semen. Normal concentration is at least 20 million sperm cells per milliliter of semen.

  • Morphology: The shape and size of the sperm. A healthy sperm cell will have a shape similar to a tadpole. The sperm's oval head contains the genetic material, the center provides energy and the tail propels the sperm forward.

Using the strict criteria put forth by the World Health Organization (1999), studies show lower pregnancy rates with less than 15% normal forms. Furthermore, experts believe that abnormally shaped sperm cannot fertilize an egg.

Motility, speed and morphology appear to be the most important factors to assess the fertilizing capability of sperm. Despite a low sperm count, many men with high-quality (viable and highly mobile) sperm may still be fertile.

By combining acupuncture, herbal medicine and supplements we have been able to effectively enhance and improve the quality of sperm. Not only do the count, morphology and motility improve but sperm fragmentation is often successfully treated.

Another excellent application of the Berkley Center's protocol is varicocelectomy recovery. One of the causes of lack of improvement in sperm quality and count after a varicocelectomy is due to a lack of blood flow to the testicles. The proper application of acupuncture, herbal medicine and supplements has been shown to successfully enhance blood flow to the testicles and facilitate healing and significant improvement after varicocelectomy.
