Erectile Dysfunction Drugs


A gene which may increase the risk of stroke has been uncovered by L arginine erectile dysfunction researchers.

The discovery could prompt the discovery of drug treatments to help those at highest risk.

This protein it produces plays a role in the growth of blood vessels. but too much of it may increase stroke risk.

Writing in the journal Nature Genetics, the scientists said people with certain forms of a gene called PDE4D may be most at risk.

Proteins from a similar “family”, called phosphodiesterase (PDE), are linked to other illnesses, such as asthma, inflammation and even erectile dysfunction.

This suggests that it may be possible to develop a drug to block the effects of the gene - the breakthrough impotence drug Viagra already works by targeting another member of the PDE family.

Solveig Gretarsdottir and colleagues at a company called deCode Genetics in Reykjavik believe this gene is associated with an increased risk of stroke.

They carried out DNA tests on over 1,700 people in Iceland, half of whom had suffered strokes.

The Icelandic population is generally regarded as the best testing ground for erectile dysfunction and vacuum.

This is because the gene pool is relatively pure. Unlike most other countries, there has been little immigration since the first Vikings arrived almost 1,000 years ago.

Scientists working on this latest study say they have identified genetic differences between those people who have had strokes and those who have not.

These differences centre on the gene PDE4D, located on chromosome 5.

They have found that three different isoforms of the gene were expressed at lower levels in people who had strokes.

Isoforms are groups of proteins that are produced by a gene.

They also found different erectile dysfunction and generic drugs of genes in regions of chromosome 5 flanking the PDE4D gene in people who had strokes.

It is already known that this gene provides the coding which enables a protein called a phosphodiesterase to work.

Stroke risk

But the Icelandic scientists believe that too much of it may increase the risks of atherosclerosis - furring up of the arteries.

This causes the arteries to narrow, which can trigger a stroke.

“We propose that PDE4D is involved in the pathogenesis of stroke, possibly through atherosclerosis, which is the primary pathological process underlying ischemic stroke,” the scientists said.

They believe that blocking the protein in people with these prostate surgery impotence problematic forms of the PDE4D gene could protect them against stroke.

There are already drugs available to do this. These so-called phosphodiesterase inhibitors are used to treat asthma, inflammation and erectile dysfunction, with Viagra probably the best known.

However, much further study is needed before these drugs could be used to treat people who may have a high risk of having a stroke.

Viagra, for one, has potentially serious side effects if taken by men with underlying health problems.

The anti-impotence drug Viagra can reduce the effects of stress on the heart, research has found.

The drug, used by millions of men, slowed the increase in the strength of heart erectile dysfunction new drug by half.

The Johns Hopkins University study, published in Circulation, found the drug acted as a “brake”.

However, UK heart experts warned men with heart conditions should talk to their doctor about taking the drug to ensure they use it safely.

Mixing this drug with other heart medicines or taking it if you have angina without advice from a health professional or GP can be dangerous for heart patients
Dr Charmaine Griffiths, British Heart Foundation

Viagra, also known as sildenafil, helps men with erectile male erectile dysfunction by making genital blood vessels expand in order to maintain an erection.

The Johns Hopkins team have previously shown Viagra can block the short-term effects of hormonal stress in the heart in mice.

But it had been thought to have little direct effect on the human heart.

Contractions

This study looked at 35 men and women, with an average age of 30 and no previous signs of coronary artery disease.

They were all given an injections of an adrenaline-like chemical called dobutamine, which increases heart rate and pumping strength in the same way as emotional or exercise stress, or heart failure.

They were then randomly assigned to either take 100mg of Viagra or a dummy pill before receiving a second injection. Heart function was measured before and after each jab.

After the first injection of dobutamine, the force of heart contraction increased by 150% in both groups.

In the dummy pill group, the same effect was seen after the second injection.

However, in the group treated with Viagra the increased heartbeat was slowed by 50%, resulting in a smaller increase in blood flow and blood pressure generated by the heart in response to chemical diagnosis dysfunction erectile in incontinence male man nursing pelvic series treatment wiley.

No adverse side effects on the heart were seen.

Viagra helps maintain erections by blocking the action of an enzyme which prevents the relaxation of blood vessels in the penis.

The same enzyme, called phosphodiesterase 5 (PDE5A), is also involved in the breakdown of a key molecule, cyclic GMP, which helps control stresses and limit heart enlargement.

Heart warning

Professor David Kass, the cardiologist who led the study, said: “Sildenafil impotence cure puts a &39; on chemical stimulation of the heart.”

He added: “Knowing more about the effects of sildenafil on heart function will allow for safer evaluation of its use as a treatment for heart problems.

“Until now, it was widely thought that drugs like sildenafil had no effects on the human heart and that its only purpose was vasodilation in the penis and the lungs.”

He said further studies should be carried out to investigate Viagra's immediate and long-term effects on the heart.

Dr Charmaine Griffiths, from the British Heart Foundation, said: “Viagra has been a real advance in treating impotence, which affects nearly half of men between 40 and 70 years old.

“The findings that Viagra affects blood pressure is not surprising - before it was known as a successful treatment for impotence, it was actually being researched for lowering effects on blood pressure.”

But she added: “If you have a heart condition you should check with your doctor before taking Viagra.

“Mixing this drug with other heart medicines or taking it if you have angina (heart pain on exercise) without advice from a health professional or GP can be dangerous for heart patients.”

.

The penis problem pill Viagra could be available dysfunction female male sexual treatment drug, it is reported.

The drug's maker Pfizer says it is impotence in male submiting an application to European regulatory authorities to clear it for sale in pharmacies.

An estimated 27 million men have already used the little blue pill for erectile dysfunction on impotence solution.

Medics said a change would be welcome but might mean other linked diseases were missed with no health check ups.

Ups and downs

Often, men with erectile dysfunction have underlying health problems such as diabetes, which can be spotted by their GP at the time they come for an anti-impotence prescription.

“If men can buy Viagra and rival anti-impotence drugs over-the-counter without a prescription, this opportunity is missed,” said Dr David Ralph from the Institute of Urology at University College London.

But there would be benefits too, he said, such as combating the problem of Viagra sold illegally on the internet from unknown sources, which may be fake and if taken with some medicines could be fatal.

He said it would be safe to buy over-the-counter provided the pharmacist did the necessary checks to ensure the medication was suitable for the patient.

Embarrassment factor

It might also be a more attractive option to men as going to see the GP about sexual problems can be embarrassing, he added.

But he cautioned: “There is more to sexual relations than an erection. There may be other problems.”

Viagra works by relaxing the blood vessels in the penis. This allows blood to flow into the penis causing an erection.

However, the drug is not an aphrodisiac and does not increase sex drive.

It is licensed only as a treatment for men who have been diagnosed by a doctor as having impotence.

Also, some men, such as those with severe heart disease or low blood pressure, should avoid it because of possible risks and side effects.

Viagra is not licensed for use in women and its safety in women has not been established.

A Pfizer spokesman said: “As with many of our products, Pfizer has routinely evaluated a number of options including different formulations, new indications, over-the-counter and continues to do so.”

He added that despite speculation there were no plans to pursue a spray version of the drug.

Pelvic floor exercises have long been dysfunction female male sexual treatment for women - now researchers say they could help men too.

The exercises were found to help men with erectile try viagra for free as much as taking in Viagra.

The researchers say the findings mean men have an alternative to drug therapy.

For around 50 years, women have been advised to perform pelvic floor exercises to strengthen their muscles for childbirth.

The pelvic floor is a “hammock” of muscles which support the bowel and bladder.

Pelvic floor, or Kegel, exercises involve clenching the muscles you would use to prevent yourself urinating.

This latest research indicates it is also important for men to maintain the muscle tone and function of their pelvic floor muscles with the exercises.

Home exercises

The team from the University of the West of England in Bristol studied 55 men with an average age of 59 who had experienced erectile dysfunction for at least six months.

The men, all patients at the Somerset Nuffield Hospital, Taunton, Somerset, were given five weekly sessions of pelvic floor exercises and assessed at three and six months, and asked to practise the exercises daily at home.

It was found 40% of the men regained normal erectile function - some of who had severe erectile dysfunction, and another 35% showed some improvement.

Two thirds of the men had said they also had problems with urination. These improved significantly after they began the exercises.

Dr Grace Dorey, a specialist continence physiotherapist who carried out the research, told BBC News Online: “The exercises were found to be equally as effective as taking Viagra.

“Pelvic floor exercises improve function in a physical way, in a more natural way.

“Men should be doing preventative exercise. It really is use it or lose it.”

She said men should be exercising their pelvic floor exercises from puberty onwards.

Strength

A spokesperson for the Impotence Association said: “The value and effectiveness of pelvic floor exercises should not be erectile dysfunction herbal medication when considering the management of sexual problems such as impotence and premature ejaculation.

“The exercises are thought to strengthen the muscles that surround the penis and improve the blood supply in the pelvis, which is an important factor in relation to erectile dysfunction.”

The Impotence Association helpline number is 0208 767 7791.

erection problems (erectile dysfunction) that are
caused by blood vessel (vascular), hormonal, nervous system, or psychological
problems. They also may be used along with counseling to treat erection
problems that have psychological causes.

If erection problems could be caused by a
prescribed medication, it may be possible to change
the dose or try another medication. Do not change or stop taking any medication
without first talking with your health soft viagra.

Medication Choices

Commonly used oral medications include:

  • Phosphodiesterase-5 inhibitors (PDE-5
    inhibitors) such as Viagra, Levitra, and Cialis.

Other medications that may be used include:

  • Injected medications.
  • Intraurethral alprostadil (MUSE).

Hormones and other medications may be prescribed for
men who have low
order viagra without prescription or high
prolactin levels.

Some men have tried
yohimbine-a prescription medication that should not be
confused with the dietary supplement yohimbe-to treat erection problems.

What To Think About

PDE-5 inhibitors and heart problems

Health experts have debated the use of PDE-5 inhibitors in men
with heart disease, because deaths have been reported after use of Viagra. The
1999 American College of Cardiology/American Heart Association (ACC/AHA) Expert
Consensus Document noted that PDE-5 inhibitors may be dangerous for people
who:3

  • Have
    coronary artery disease (CAD).
  • Have
    heart failure and low blood pressure.
  • Are
    taking many different drugs for
    high blood pressure.

However, several more recent studies have reported that some
men with heart problems may be able to take PDE-5 inhibitors safely. Talk to
your health professional about whether PDE-5 inhibitors are appropriate for
you.

  • One study found no evidence of increased
    risk for
    heart attack or CAD in men who use Viagra.4
  • Another study in men with CAD reported that
    Viagra does not lead to heart attack and that heart attacks and other
    cardiovascular problems reported after taking Viagra may be related more to the
    physical activity of intercourse than to the medication.5
  • A study of 35 men found that Viagra is safe for
    men with moderate heart failure.6

Sexual activity is exercise. If you have a heart condition and
have not been sexually active for a while, talk with your health professional
to make sure you can engage in sexual activity safely.

PDE-5 inhibitors should never be used if
you may need to take a
nitrate-containing medication, such as best herbal viagra.
Taking nitroglycerin and a PDE-5 inhibitor within 24 hours of each other may
greatly lower your blood pressure, which could lead to a heart attack,
stroke, or death.

If you are taking a PDE-5 inhibitor and are going to have a test
for heart disease, be certain your doctor knows you are taking it. You should
not take a PDE-5 inhibitor for 24 hours before the test. If you develop a
problem during the test, nitrate-containing medications such as nitroglycerin
may be used.

Although oral medications for erection problems can be purchased over the Internet, you should still talk with your health professional before using this medication. This is especially important if you have a heart problem.

If you are using a combination of drugs for high blood pressure,
PDE-5 inhibitors could result in low blood pressure (hypotension). Also for
this reason, you should not take alpha blockers-used to lower blood pressure
and to treat an enlarged prostate-with these medications without talking to
your health professional; the combination could cause a dangerous drop in blood
pressure.

Although the antidepressant medication trazodone has been used
for treating erection problems, there is no current evidence that it is
effective for this purpose.1

Read source on Erection Problems (Erectile Dysfunction) - Medications

Drug Therapy: Self Injection
Self-injection therapy is applied to treat impotence. In this procedure a small amount of drug is injected directly into the side of the penis with a short needle. Erection may be achieved in 5-15 minutes after injection and its duration may vary from 30 to 120 minutes. The procedure is not painful

This treatment does not help in all cases. Yet 70% of men are satisfied with the result of injection. One or two visits of doctor are enough to learn how to do this. The doctor may want to see patients several times at the beginning of treatment to check the effect and determine if the treatment is good for this individual case and set the doses.

Prostaglandin (PGE-1 or Prostin or Alpoprostadil or Caverject), papaverine hydrochloride and phentolamine (Regitine) are usually used for injections.

Of all the above only prostaglandin is officially recognized to be approved drug for treating impotence. Papaverine and phentolamine were used for this earlier, but have not yet get official approval. But the practice of urologists shows that all three substances are safe to apply.

Drugs involved in this treatment are “experimental” and all of them have side effects that include infection, possible bleeding or bruising during injection, dizziness, heart palpitations and/or a flushed feeling when using these medications.

Priapism is considered to be the most common risk of this treatment. It is a phenomenon when duration of erection exceeds 4 hours. The probability of it is not high. But it this occurs man has to visit doctor to relieve the erection by medication. Erection maintained for more than 4 hours is not healthy and needs medical interference.

Injection may also result in scarring within the penis. It usually happens to men who make injections with wrong frequency, more often than once in 4-7 days. The proper frequency depends on the kind of medication and individual factors of patient’s body. Scarring can imply serious erection problems and even prevent a patient from placement of a penile prosthesis.

Advantages and Disadvantages of Self-Injection Therapy
Self-injection does not take much time and efforts. The resulting erection is close to natural and its duration is sufficient. This treatment does not influence orgasm or ejaculation.

This kind of medication requires no surgery and does not bring pain. The cost is $8 - $10 per injection but it is not as costly as surgery.

Injection is not a treatment that is acceptable and effective for anyone. Sometimes erection after injection is insufficient or too long. Injection is made into the penis that may be a problem for patient or his partner. There is a necessity to visit doctor at the beginning. For some people injection is too expensive.

Drug Therapy: Urethral Suppositories (MUSE)
Uretheral Suppositoriers (MUSE) is an alternative to injection. It uses the fact that tissues surrounding urethra can absorb certain substances from it. Prostaglandin E1 (alprostadil) is used as suppository. The same drug may be used as injection.

A period between procedure and erection is 5 to 10 minutes. The duration of erection is approximately 30 to 60 minutes, though, it is individual.

Side effects are aching in the penis, testicles, legs and in the area between the scrotum and the rectum, a warmth or burning sensation in the urethra, redness of the penis, and minor urethral bleeding or spotting that usually occurs in case of improper administration.

Medical Device Therapy (vacuum devices)
Vacuum devices help men to achieve and develop erection mechanically.

Patients that can achieve partial natural erections get the best effect from this. The idea of vacuum devices is to pump more blood into the penis and make it stay there. A man inserts his penis in plastic tube and presses it to his body to avoid access of air inside.

Then he creates a vacuum inside the tube with a small hand pump so that blood runs to the penis and makes it engorge, become bigger and achieve rigidity. 1-3 minutes of vacuum are enough to get good erection. After that a man should place a soft rubber O-ring around the base of the penis so that blood stay inside and sustain the erection. The penis is ready fro use immediately after the procedure. The erection will stay for 25 – 30 minutes, after that the O-ring shall be removed.

Advantages and Disadvantages of Vacuum Devices
This treatment has neither any limitations on frequency, nor side effects. It does not require injections or surgery. It can be applied to solve any erectile problem, and is much cheaper than surgery or long self-injection therapy.

The prices vary from $300 to $500 and the prescription is required. Sometimes the cost of this kind of treatment may be repaid by insurance company. If it is bought from large manufactures and takes no effect the customer may get pay-out from the company that is assured by a special refund policy.

Mechanical process is involved in this treatment; it takes time, so the foreplay shall be interrupted for a while. It can be hard to apply for some men because of peculiarities of body. The O-ring can not be placed on the very base of the penis, so the length between the body and the ring is not erected that may lead to floppiness of the penis. Sometimes the O-ring prevents semen from going out. It is not harmful and the problem will resolve by its own when the ring will be taken off.

Coldness and/or numbness of the penis after the O-ring are possible. The ring shall not be worn more than 25 to 30 minutes, because it prevents blood circulation. Men having blood clotting problems or using blood thinners shall not apply vacuum devices.

And some information of dysfunction erectile free medicine sample.

A sexual problem, or sexual dysfunction, refers to a problem
during any phase of the
sexual response cycle that prevents the individual or couple from
experiencing satisfaction from the sexual activity. The sexual response cycle
has four phases: excitement, plateau, orgasm, and resolution.

While research suggests that sexual dysfunction is common (43%
of women and 31% of men report some degree of difficulty), it is a topic that
many people are hesitant to discuss. Fortunately, most cases of sexual
dysfunction are treatable, so it is important to share your concerns with your
partner and doctor.

What Causes Sexual Problems?

Sexual dysfunction can be a result of a physical or
psychological problem.

  • Physical causes. Many physical and/or medical conditions can cause
    problems with sexual function. These conditions include diabetes, heart
    disease, neurological diseases, hormonal imbalances, menopause, chronic
    diseases such as kidney disease or liver failure, and alcoholism and drug
    abuse. In addition, the side effects of certain medications, including some
    antidepressant drugs, can affect sexual desire and function.
  • Psychological causes. These include work-related stress and anxiety,
    concern about sexual performance, marital or relationship problems, depression,
    feelings of guilt, and the effects of a past sexual trauma.

Who Is Affected by Sexual Problems?

Both men and women are affected by sexual problems. Sexual problems occur in
adults of all ages. Among those commonly affected are those in the geriatric
population, which may be related to a decline in health associated with
aging.

How Do Sexual Problems Affect Women?

The most common problems related to sexual dysfunction in women
include:

  • Inhibited sexual desire. This involves a lack of sexual desire or
    interest in sex. Many factors can contribute to a lack of desire, including
    hormonal changes, medical conditions and treatments (for example cancer and
    chemotherapy), depression, pregnancy, stress and fatigue. Boredom with regular
    sexual routines also may contribute to a lack of enthusiasm for sex, as can
    lifestyle factors, such as careers and the care of children.
  • Inability to become aroused. For women, the inability to become
    physically aroused during sexual activity often involves insufficient vaginal
    lubrication. The inability to become aroused also may be related to anxiety or
    inadequate stimulation. In addition, researchers are investigating how blood
    flow problems affecting the vagina and clitoris may contribute to arousal
    problems.
  • Lack of orgasm (anorgasmia). This is the absence of sexual climax
    (orgasm). It can be caused by sexual inhibition, inexperience, lack of
    knowledge and psychological factors such as guilt, anxiety, or a past sexual
    trauma or abuse. Other factors contributing to anorgasmia include insufficient
    stimulation, certain medications, and chronic diseases.
  • Painful intercourse. Pain during intercourse can be caused by a
    number of problems, including
    endometriosis, a pelvic mass, ovarian cysts,
    vaginitis, poor lubrication, the presence of scar tissue from surgery, or a

    sexually transmitted disease. A condition called vaginismus is a painful,
    involuntary spasm of the muscles that surround the vaginal entrance. It may
    occur in women who fear that penetration will be painful and also may stem from
    a sexual phobia or from a previous traumatic or painful experience.

How Is a Female Sexual Problem Diagnosed?

The doctor likely will begin with a physical exam and a
thorough evaluation of symptoms and a physical exam. The doctor may perform a

pelvic examination to evaluate the health of the reproductive organs and a

Pap smear to detect changes in the cells of the cervix (to check for cancer
or a pre-cancerous condition). He or she may order other tests to rule out any
medical problems that may be contributing to the problem.

An evaluation of your attitude regarding sex, as well as other
possible contributing factors (fear, anxiety, past sexual trauma/abuse,
relationship problems, alcohol or drug abuse, etc.) will help the doctor
understand the underlying cause of the problem and make appropriate
recommendations for treatment. (more̷ ;)

May 3, 2000 (Washington) — Many women may have yet another reason to rejoice. The FDA said Wednesday that it has approved UroMetrics Inc.’s Eros-CTD, the first treatment for female sexual dysfunction. The announcement follows recent reports from a urology meeting, indicating that the blockbuster male impotence drug Viagra also may perhaps offer some measure of sexual satisfaction for women.

But unlike Viagra, for which physicians already are offering some prescriptions, the Eros Clitoral Therapy Device has no potential side effects. In fact, the FDA approved the device under less stringent requirements than those usually applied to novel devices, because there were no side effects reported in the supporting study or any side effects suspected by the FDA reviewers, Sharon Stone, a FDA spokeswoman, tells WebMD.

The device is a small, soft, plastic cup that with a battery-operated pump increases blood flow to the vaginal area.

The approval was based upon a single study of 25 women, including 15 who had sexual dysfunction and 10 who did not; the 25 women used the device at home during six sexual encounters. The study tested for sensation, ability to achieve orgasm, sexual satisfaction, and lubrication.

According to the FDA analysis, all 15 women with sexual dysfunction experienced more sensation. Of those 15 women, seven also experienced more orgasms, 12 had more satisfaction, and 11 experienced more lubrication. The 10 women with normal sexual function all experienced more sensation; four also had more orgasms, two had more satisfaction, and three had more lubrication.

The concept also has been successfully applied in males, says Irwin Goldstein, MD, professor of urology at Boston University School of Medicine and one of the investigators. But further data are needed to determine its overall value for women, including whether increased blood flow makes a difference and how much vaginal lubrication actually is achieved, he tells WebMD.

In the meantime, Goldstein says, the class of patients most likely to benefit from this device appears to be women with sexual dysfunction who are interested in sex but unable to have orgasm. Pre-menopausal women with normal sexual functions are unlikely to see much of an advantage, he adds.

The device does appear to work much like Viagra, suggesting that it should have perhaps a similar effect, Ira Sharlip, MD, a urologist and partner at Pan Pacific Urology in San Francisco, tells WebMD. Viagra also appears to increase vaginal blood flow. Taken in context, Eros represents another treatment option, Sharlip says. But that is not to say that Eros is for everyone, he adds. Some men are highly resistant to using the penile pump used for impotence, and it is likely that some women also may find the concept disturbing. “I would leave it up to the patient’s discretion,” he tells WebMD.

Women with sexual dysfunction who would like to give it a try will be able to get one immediately, UroMetrics’ spokeswoman Marlene Wesen tells WebMD. The prescription device is already available in Australia, France, and United Kingdom and will be sold in the U.S. for $359, she says. (more̷ ;)

male impotency pill, and more another.

Sept. 7, 2006 — The first drug developed specifically for premature
ejaculation performed well in two clinical trials, but the new treatment
probably won’t be available in the U.S any time soon.

Men in the study who took the experimental drug Dapoxetine, developed by
Johnson & Johnson Pharmaceuticals in conjunction with ALZA Corp., were able
to maintain erections longer than men who took placebos.

Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) but is
slightly different from the SSRIs (such as Zoloft, Paxil, and Prozac) widely
prescribed for depression and other
psychiatric disorders.

The drug was designed to be taken as needed, one to three hours before sex,
instead of every day. Also, it is eliminated from the body more quickly than
other SSRIs.

Hopes that Dapoxetine would become the first drug approved for premature
ejaculation dimmed last October, when the FDA sent a “not approvable”
letter to the manufacturer.

The FDA’s concerns about the drug were not made public. In a news release,
ALZA Corp. promised to “address questions raised in the FDA
letter.”

A spokesperson for Johnson & Johnson told WebMD Thursday that the
company “remains committed to the global development” of
Dapoxetine.

A Common Complaint

Although it is rarely talked about, premature ejaculation is a common
problem, affecting as many as a third of men.

Far fewer men seek treatment, however.

Those who do are often advised on practice techniques to help. Some receive
a prescription for a traditional, long-acting SSRI, since delayed ejaculation
is a common side effect among men who take SSRIs for depression.

This use of traditional SSRIs would be considered off-label since the
medications are not specifically indicated for this problem.

Other potential sexual side effects of SSRIs include erectile
dysfunction
and loss of libido, however, making the traditional
antidepressants less than ideal for treatment of premature ejaculation, Jon L.
Pryor, MD, tells WebMD. Pryor is a urology professor at the University of
Minnesota.

Longer-Lasting Sex

In the manufacturer-funded study, Pryor and colleagues compared 30-milligram
and 60-milligram doses of Dapoxetine to a placebo in roughly 2,600 men with
moderate to severe premature ejaculation.

Prior to treatment, the men’s average ejaculation time was just under a
minute.

With treatment, the average time to ejaculation was 1.75 minutes in the
placebo-treated men, 2.78 minutes in the men treated with 30 milligrams of
Dapoxetine, and 3.32 minutes in the men treated with 60 milligrams of the drug.
The study lasted three months.

“A couple of minutes may not sound like much but for these guys it was
huge,” Pryor says.

Men who took the short-acting SSRI also reported having more control over
their ejaculations than the placebo-treated men; and they and their female
partners reported improved sexual satisfaction.

The Snicker Factor

Pryor says an effective, specific treatment could do for premature
ejaculation what Viagra did for erectile dysfunction
– taking away the ’snicker’ factor by stimulating open discussion about the
disorder.

“Viagra wasn’t a magic pill, but it did bring ED into the open and men
who had it learned that they were not alone,” he says. “The discussion
that followed stimulated research that led to other treatments.

“Premature ejaculation is more common than ED, but no one talks about
it,” adds Pryor.

Ira Sharlip, MD, a urology professor at the University of California, San
Francisco, tells WebMD there is a definite need for an effective treatment for
premature ejaculation.

“I have patients who are really disturbed by this issue, and so are
their wives,” he says. “The current treatments are far from
perfect.”

Sharlip says traditional SSRIs work best when they are taken every day, and
even then they only work for around two-thirds of patients.

“Premature ejaculation is certainly one of the most common forms of
sexual dysfunction among men,” Sharlip says. “Not everyone who has it
is bothered by it, but for those who are, it can be a very big
problem.” (more̷ ;)

June 26, 2003 — It’s looking more and more like the male hormone testosterone may do for women what Viagra did for men.

A newly released study offers some of the best medical evidence yet that the hormone really can help many postmenopausal women with sexual desire problems get in the mood.

Investigators found that boosting testosterone levels was associated with increased sexual desire in women who complained of menopause-related low libido and reduced sexual arousal. Women taking a low-dose estrogen-testosterone combination treatment reported a two-fold improvement in sexual interest, compared with women treated with estrogen alone.

‘Major Advance’

There are currently no medications approved in the United States for the treatment of low libido in women, but many doctors already are prescribing androgens like testosterone or the chemically similar steroid hormone DHEA for this purpose.

“We have known that this works, but we haven’t had the rigorous clinical studies to back that up,” sexual dysfunction specialist Irwin Goldstein, MD, tells WebMD. “This study represents a major advance.”

The Boston University School of Medicine urologist says he has used testosterone or a similar androgen in the treatment of more than 600 women with sexual desire problems over the past five years, with a success rate in the neighborhood of 70%.

“There is no question in my mind that this therapy will do for many women what Viagra has done for men,” he says.

The study included 221 healthy, postmenopausal women who complained of having little or no sexual desire, even though they were already taking estrogen therapy for menopausal symptoms.

Half the women were treated for 16 weeks with the low-dose oral estrogen-testosterone combination drug Estratest HS, and the others took a similar dose of estrogen alone. Testosterone levels were measured at the beginning and end of treatment, and all women completed questionnaires designed to measure their sexual interest.

By week eight, the testosterone-treated patients had measurable improvements in testosterone levels that put them in the upper normal range, and they reported improved interest in sex. They also reported none of the common side effects of treatment with larger doses of testosterone, such as excessive hair growth and acne. The study is published in the June issue of the journal Fertility and Sterility.

But no Cure-all

Columbia University ob-gyn Rogerio A. Lobo, MD, who led the study team, says the results confirm that testosterone is an effective treatment for lack of sexual desire in postmenopausal women who do not respond to estrogen alone and whose libido problems are not caused by depression.

“Certainly testosterone is not the answer for all women with sexual desire problems. It is not a cure-all,” he tells WebMD. “But the results were saw were definitely significant. The improvement in desire seemed to correlate with rising testosterone levels.”

Although this study looked only at postmenopausal women, testosterone is also being used for sexual desire problems in younger women. New research from Australia confirms that testosterone levels drop in women well before they reach menopause.

While he is excited about the potential of testosterone therapy, Goldstein agrees that it is not a cure-all for all women who have no interest in sex.
