Sexual Function It is necessary to establish a basic understanding of normal sexual function prior to the discussion of  potential mechanisms for drug-induced pathology.

Normal male sexual function requires

(1) an intact  libido,

(2) the ability to achieve and maintain  penile erection,

(3) ejaculation, and

(4) detumes- cence.

The major anatomic structures of the penis that are involved in erectile function include  the paired corpora cavernosa and the single corpus  spongiosum that encloses the urethra. The tunica  albuginea, a collagenous sheath, individually sur- rounds each corpus. The microarchitecture of the  corpora is composed of a mass of smooth muscle  which contains a network of endothelial-lined  lacunar spaces. Penile tumescence leading to erection depends on the increased flow of blood into  the lacunar network after complete relaxation of  the arteries and corporal smooth muscle. Subse­ quent compression of the trabecular smooth muscle against the fibroelastic tunica albuginea causes  a passive closure of the emissary veins and accu- mulation of blood in the corpora. In the presence  of a full erection and a competent valve mechanism, the corpora become noncompressible cylin- ders from which blood cannot escape. The central nervous system exerts an important influence by either stimulating or antagoniz- ing spinal pathways that mediate erectile function  and ejaculation. These interactions are mediated  by a combination of central and peripheral innervation. Canadian pharmacy viagra – cheap ed medications online.

Sensory nerves that originate from  receptors in the penile skin and glans converge to  form the dorsal nerve of the penis, which travels  to the S2­S4 dorsal root ganglia via the pudendal  nerve. Parasympathetic nerve fibers to the penis  arise from neurons in the intermediolateral columns of S2­S4 sacral spinal segments. Sympa­ thetic innervation originates from the T-11 to the  L-2 spinal segments and descends through the  hypogastric plexus. Neural input to smooth mus- cle tone is crucial to the initiation and maint nance of an erection. There is also an intricate interaction between the corporal smooth muscle  cell and its overlying endothelial cell lining. Nitric oxide, which induces vascular relax- ation, promotes erection and is opposed by  endothelin­1 (ET­1), which mediates vascular  contraction. Nitric oxide is synthesized from l­arginine by nitric oxide synthase (NOS),  and is released from the nonadrenergic, noncho- linergic (NANC) autonomic nerve supply to act  postjunctionally on smooth muscle cells. Nitric  oxide increases the production of cyclic  3¢,5¢­guanosine monophosphate (cyclic GMP),  which interacts with protein kinase G and  decreases intracellular calcium, causing relax- ation of the smooth muscle. Cyclic GMP is grad- ually broken down by phosphodiesterase type 5  (PDE­5). Inhibitors of PDE­5, such as the oral  medication sildenafil, maintain erections by  reducing the breakdown of cyclic GMP.

However,  if nitric oxide is not produced at a basal level, the  addition of PDE­5 inhibitor is not effective, as  the drug facilitates but does not initiate the initial  enzyme cascade. In addition to nitric oxide,  vasoactive prostaglandins (PGE1 , PGF2a) are  synthesized within the cavernosal tissue and  increase cyclic AMP levels, also leading to the  relaxation of cavernosal smooth muscle cells. Ejaculation is stimulated by the sympathetic  nervous system, which results in contraction of  the epididymis, vas deferens, seminal vesicles,  and prostate, causing seminal fluid to enter the  urethra. Seminal fluid emission is followed by  rhythmic contractions of the bulbocavernosus  and ischiocavernosus muscles, leading to ejacu- lation. Detumescence is mediated by norepinephrine released from the sympathetic nerves,  the release of ET­1 from the vascular surface,  and contraction of smooth muscle induced by  the activation of postsynaptic  a-adrenergic  receptors. These events increase venous out- flow and restore the flaccid state. Venous leak  can cause premature detumescence and is  thought to be caused by insufficient relaxation of  the corporal smooth muscle.

Erectile dysfunction (ED) may result from  three basic mechanisms:

(1) failure to initiate  (psychogenic, endocrinologic, or neurogenic);

(2) failure to fill (arteriogenic); or

(3) failure to  store (venoocclusive dysfunction) adequate  blood volume within the lacunar network.

The inability to initiate an erection may have psychogenic, vasculogenic, endocrinologic, or neuro- genic etiologies. These categories are not  mutually exclusive, and multiple factors contribute to ED in many patients. ED has also beencommonly associated with prescription and non- prescription medications. The remainder of this chapter focuses on the literature and the hypoth- esized mechanisms of dysfunction surrounding  this relatively common clinical entity is contributing to the sexual  addition, physicians should tion to the presence of othe (i.e., the patient’s psychosoc exist outside of the disease  drug in question. The final s addresses management strat ment of drug­induced ED.

You can feel it coming. Your shoulders feel tight, and there appears to be some kind of vice grip clutching your head like a bird of prey. You almost feel queasy because the pain is so immense. You cannot open your eyes without squinting because the light makes it worse. You finally give in and pop a few pain relievers all the while wondering how long you have to be attached to medication to feel decent. This is what headache pain relief often amounts to, but that is unfortunate.

Pretty much every person on the planet has experienced a headache at some point in their lives. Whether it is from squinting to read, a head cold or caffeine withdrawal, there are numerous reasons why a person gets a headache. However, it is not always necessary to take medication to rid yourself of the pain. There are many other more natural ways to get headache pain relief. Here are a few to try:

Massage: Trigger point massage is the most effective for headaches. There are all kinds of knotted up muscles in our bodies, and trigger point therapy can help release those areas, thus relieving the pain that they can cause in other areas of the body.

Acupuncture: The idea behind this ancient form of healing is that the body has energy centers that get blocked. Acupuncture is well known for its ability to relieve headaches and many other kinds of pain and illness.

Magnesium: Try taking some powdered magnesium as it is the calming mineral. It loosens muscle tension and relaxes the body.

Drink more water: If you are not drinking at least 8 glasses of water a day (and more if you exercise), drinking more water is one simple way to rid yourself of headaches. The body will produce headaches even in mild cases of dehydration, so start drinking your water.

Exercise: If you are not exercising on a regular basis, you should because “feel good” hormones are produced when you exercise. They are natural pain killers, so they work like a charm for headaches.
Headache pain relief can be simple and easy if you know what to try. You may have to try a few different techniques before finding the one that is right for you, but don’t give up. Getting away from medications is certainly worth the effort for your long term health.

There are just too many people who are ill from graves disease.

Hyperthyroidism, Graves disease and hypothyroidism are common disorders dealing with an overactive thyroid that produces too much hormone or an underactive thyroid that doesn’t put out enough hormones.

Symptoms from these conditions are increased appetite, weakness, depression, weight loss or weight gain, heart palpitations, hair loss and many other issues.

Conventional medicine wants to treat these symptoms with toxic medications and useless surgeries that compound your problem. These solutions only mask the symptoms never addressing the real problem for the condition.

Thyroid disease is actually a warning sign from the body telling you that there is an imbalance. Until these imbalances are addressed, graves disease and all diseases will continue to exist.

When we abuse or bodies through bad eating habits and other negative habits our bodies become weak and unable to remove toxins, germs, bacteria and other harmful pollutants.

What is causing us to be sick and come down with thyroid disorders? The answer is that are bodies are over acidic.We eat things that deplete our bodies of the nutrients it needs.

The body struggles to get the energy it needs from cells. It will begin to steal this energy from other organs in order for it to function properly.

That can leaves organs such as the thyroid weak and unable to function at the proper levels. The body goes into survival mode when the body is high in acid it cannot fight off diseases and kill toxins.

These acids will settle into the weakest parts of the body that have lost energy to fight off toxins and begin to cause major health problems.

If you want to be free of thyroid disease, hypthyroidism, graves disease and hyperthyroidism, you have to start by changing how you live and what you eat.

To reverse health issues like Graves disease there are five vital things that need to be done. Once you implement these things into your life, you will begin to notice your health improving and your symptoms diminishing.

Diseases are nothing more than symptoms of unbalance in the body. We live unhealthy lifestyles and have unhealthy diets that contribute to the decline of our health. It takes years of abuse of nutrition and acid build up from poor elimination.

By following five vital steps, your body will be back in balance and you will be on the road to health.

The general proportion of blood is 20% acidic in nature and 80% alkaline. When the proportion of the acidity increases in the blood level, it affects the digestive system and this condition this generally termed as heartburn or heartache. It leads to sourness in the abdominal region and physicians call this as acidity and treat it accordingly.

Drugs are not the only answers to this problem. It is not possible to forget the numbers of deaths caused by the drug propulsid which was used to treat the heartburn. It was then withdrawn from the market after facing ligations. Hence, here comes the need to look for alternative and effective ways to cure reflux.

A detoxification diet is an effective natural remedy in curing this heartburn. It is highly recommended to drink about 1 gallon of purified water along with the probiotics to restore the normal functioning of the body parts. Drinking water in excess will help to keep the urine in a light yellow shade.

The food items consumed must be dry. Spicy foods can be consumed but to a restricted level. However, patients are encouraged to try various kinds of food items to check the results. The consumption of pickles and tea should be reduced to a greater extent. Potato can be a good natural remedy as it is alkaline in nature. The presence of potassium salt will restrict the acidity developed in the body system. Garlic is the most sought by the acid reflux affected patients. It will kill all the pathogenic organisms that are responsible for the acid reflux. Fresh garlic must be consumed for better results. The above discussed are some of the natural remedies which can help in curing acid reflux.

Arch pain is a fairly common problem, particularly among people that spend a lot of time on their feet. Police that walk a beat, nurses, salespeople, cashiers and many other careers require constant standing and walking. In order to avoid the problem, these people need shoes that offer support and stability throughout the arches or insoles that provide support and stabilize the heel.

It is important to address the problem, as soon as it is noticed. Without support, the ankles can turn outward, which puts additional strain on the inner border of the foot. The eventual result can be flat feet.

If not corrected, flat feet can lead to problems with the ankles, knees, hips and back. The muscles in the foot can weaken, leading to excessive fatigue and lack of energy. Aching feet have a negative effect on your mood, as well.

In some of the most extreme cases, surgery is needed to stabilize the bones. These problems only get worse as time goes by, if something is not done to stop the progression.

Arch pain can be relieved by wearing shoes that have a built in arch-support. They are composed of a polypropylene shell that is flexible enough to be comfortable when walking, but rigid enough to hold the foot in a natural position when standing.

Most high quality shoes have some type of built in support for the arches. But, shoes that are thin (flip-flops, house slippers and some sneakers) are designed strictly as fashion accessories will not provide adequate support.

Supports can be added to some shoe designs to allow a person to continue to wear the shoe, if they desire. Full length, ¾ length, and “arch-only” inserts are available. Special braces can also be used to provide extra stability, prevent arch pain and help to prevent the arches from falling.

The outsoles of most dress shoes are made of hard leather. In work-oriented shoes, by contrast, the outsoles are made of natural or synthetic rubber. The heels in men’s dress and women’s casual shoes are made of rubber, as well.

Hard leather outsoles provide little or no shock absorption. They are designed mostly for sitting, although they make it easier to “slide” on a dance floor, too.

Women’s dress shoes, as a rule, provide the least support and are of the poorest designs, in terms of comfort. They are often the cause of heel, ball of foot and arch pain.

A few companies have taken to designing women’s dress shoes that are comfortable and practical. It was always possible to design a nice looking shoe that also provided necessary support. It just costs more.

Wearing cheap shoes is the cause of all kinds of feet problems. Wearing pointy-toed shoes with a small toe-box or pointy heels cause painful feet, knees, hips and back. As you may notice, those are the same problems that can be caused by flat-feet.

So, take the necessary steps to reduce foot arch pain, before you start to experience other pains in your lower body. A good foundation leads to good health.

Influenza type activity is becoming more prevalent as the flu season progresses. The H1N1 virus is now widespread in forty-eight states. Doctor and hospital visits are on the rise and the influenza death rate has increased from years past. After testing many people with the flu, the H1N1 virus has shown to be the overwhelming culprit. This flu season is definitely going to be a tough one for sure but there are measures that can be taken to prevent this spreading illness. We all definitely need to be more proactive to protect ourselves and our family when we’re at work, church, school and out shopping. So how can I prevent H1N1 you might ask? Well there are some practical steps you can take.

We can get the swine flu vaccine. I do have concerns however with the vaccine. It’s very new and was only tested on a small group of people before being issued to the general public. Health experts claim that the vaccine is created in the same way as the regular flu vaccine. If that’s the case then the concern lies with if you feel comfortable with vaccines in general.

Some other ways you can avoid swine flu is to frequently wash your hands. I found a very effective way to keep your (and your kid’s) hands clean is to take some travel size hand sanitizer with you in your pocket or purse. Using it often after touching things out in the public like door knobs, gas pumps and shopping carts can be a great asset in preventing swine flu.

You should also get plenty of sleep and eat healthy for a strong immune system. Try to avoid crowded places in tight areas, for example take the stairs instead of a packed elevator. So if you’re asking how can I prevent H1N1 I hope this gave you some helpful tips. Again this is going to be a very challenging flu season, but following some very smart and effective steps can increase your chances of not catching this terrible illness.

The decision to quit smoking can be one of the best decisions that you will make in your lifetime. Quitting smoking leads to better health, a cleaner lifestyle, and more money in your wallet. Quitting smoking is also an extremely difficult choice that can lead to headaches, crankiness, sleeplessness, and dry mouth. However, these symptoms last a week or two at the most whereas the benefits last a lifetime. If you really want to quit but can’t seem to manage it, there are plenty of products and groups that exist solely to help you quit.

If you look at smoking in a strictly logical manner, it is a wonder that people ever start to smoke in the first place. Smoking is expensive. In big cities a single pack of cigarettes can cost five dollars. Even if you live in low tax state and buy a cheap brand, you are still spending two or three dollars a pack. A conservative estimate of one pack a day comes to sixty spent on cigarettes per month and seven hundred and twenty dollars spent on cigarettes per year. You are literally burning your money with each puff. Doesn’t that make you want to quit?

Then think of the health benefits. Cigarettes contain tar and toxic gases like the kind that come out of the tailpipe of your car. Those poisons get into your lungs, decrease your lung capacity and are the leading cause of lung cancer and heart disease. Quitting smoking also improve your outer appearance. Your hair, breath, and fingers will no longer smell like smoke. After you stop staining your teeth with tobacco tar they will start to return to their natural white color. Your clothes, car, house, and even pets will smell natural again.

To quit smoking involves a lot of willpower, but it can be done. There are many steps you can take to break your habit of smoking and your addiction to nicotine. First, avoid places where you know people will be smoking. Thankfully, many cities have passed bans on smoking in bars and restaurants, so you can still go out and enjoy yourself. Find other people who are trying to quit or who have quit successfully. You may know someone, or you can find a large support community on the internet. Let these people be the outlet for your frustrations. Even if you find yourself irrationally yelling for a few days, it is better than continuing to smoke for a lifetime.

In addition to emotional support, you can get physical support from nicotine replacement products such as patches or gum. You can even smoke herbal cigarettes for a while if the action of smoking something will help you. Just keep persevering and you will be able to quit smoking in no time.

Most people who decide they need to lose weight are aiming to improve their appearance, but the health benefits of good nutrition and a sound exercise program are ultimately far more valuable.

Study after study has demonstrated that obesity is a significant threat to longevity and good health, but many people are not even aware that they are medically obese – the generally accepted definition of obesity is over 25% body fat for men, and over 32% body fat for women. An estimated 20% of American adults fit this profile.

The problem only gets worse with time: The average American adult puts on about a pound a year after the age of 25, meaning that by middle-age many people have put on 25 pounds or more. To make matters worse, your metabolism naturally slows down as you age, while at the same time, sedentary adults tend to lose one pound of lean muscle mass every year from inactivity, depressing metabolism even more.

The dangers of excess body fat range from insulin resistance and diabetes to heart disease and cancer, and the cause-and-effect relationship is not difficult to understand: If you are overweight, your heart has to work that much harder to supply fresh blood to the body, making everything from moving around to simple breathing more of an effort. Over time, this extra effort takes its toll, resulting in damage to the heart muscle.

Obesity also comes with a greater risk of high cholesterol, which can increase the chances of developing arteriosclerosis, in which the blood flow in the arteries is slowly choked off by plaque deposits, depriving internal organs of adequate blood supply and forcing the heart to pump harder, raising blood pressure. A full 25% of heart problems today can be traced directly to obesity.

While many people may be aware that obesity can damage the heart, few are aware that it can also result in a higher risk for cancer – in men, being overweight comes with a higher risk of prostate and colon cancer, while in women the risk of uterine and breast cancer is significantly higher. It is believed that excess body fat serves as storage for carcinogenic toxins in the body, and these toxins can leach from fat packed around the internal organs.

The good news is that by losing weight you can undo much of the damage caused by excess body fat and reduce your risk factors for cancer and heart disease – in fact, studies have shown that losing just 10-15% of your body weight can improve your overall heart health and cholesterol levels even more than prescription drugs in many cases.

Those who lose weight and exercise regularly have proven to be eight times less likely to die of cancer and heart disease, and 53% less likely to die of other diseases.

Even if it takes you several years to implement a healthier way of life, the results over the long term will be more than worth the effort.

Would you like to discover the best times to eat normal foods to help you burn fat?

Weight loss is a big question for every woman after she gives birth. The extra weight gained during pregnancy and dealing with post pregnancy body is what bothers every woman. The idea is to reclaim your body by getting back to shape.

A good diet for pregnancy comprises of nutritious and high-density foods. Never do any harsh diets, always ensure that you get enough nutrition especially so if you are breastfeeding.

A traditional workout system would not be able to deliver results for mums suffering from post-pregnancy belly fat, what is more needed is a targeted workout regime for the lower stomach as well as the core muscles.
