One risk factor, and this is something you do nothing about really, is age. Nail fungus have been noted to affected older people than younger people – though this is of course not to say that young people are completely immune from the nail fungus. It is just that the infection is more common among older people. Several possible medical explanations for this phenomenon have been put forward. The most plausible of these explanations is the one that sees increased exposure (as a function of age/time and hence more contact with the fungus) as one of the reasons why nail fungus are more common among older people.
It has also been noted that blood circulation tends to be impaired as people get on in years, and since diminished circulation is known to be one of the factors behind an increased risk of fungal infections, it follows that nail fungus would be expected to more among the older people in any population where such infections are common. Furthermore, it has been noted that the nails of older people tend to be thicker than those of younger people (as nails tend to thicken with time), and this is thought of as being yet another reason as to why nail fungus are more common among older people, as the thicker nails so developed with age naturally make a better habitat for the nail fungus than nails of lesser thickness.
Another risk factor for nail fungus, once again something that there is very little you can do about, is gender – where the condition has been observed to affect more men than women. Again this is not to say that women are absolutely immune from nail fungus. It is only to say that men have shown greater predisposition, on average, than women to the same infection.
Then there is heredity as another risk for nail fungus. Like the previous two, this too is something about which you really can do very little. So if either of your parents always complained of nail fungus, then chances are that you may find yourself doing the same sometime down the line. Of course, it is should be noted that heredity only translates to enhances predisposition to conditions, and is not therefore not a sure sentence that if you are genetically predisposed to nail fungus that you will get them.
If you tend to sweat heavily, especially on your feet, then you are at a greater risk of suffering from nail fungus than a person who sweats more modestly.
If you have suffered from the inflammatory skin illness called psoriasis, then you too, are at a greater risk of suffering from nail fungus infection that someone who has never had a psoriasis infection.
If you have previously suffered from the condition called 'athletes foot' you are also at great risk of suffering from nail fungus later, as is the case if you happen to have diabetes or problems with circulation in your body.
Over the years men complain of two distinct sexual problems: lack of desire and impotence. Impotence or erectile dysfunction is the inability to hold an erection long enough to pursue in sexual intercourse. Erectile dysfunction (ED) can be a total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only short erections.
Erection begins with sensory and mental stimulation. Under normal conditions, when a man is sexually stimulated, his brain sends a message down the spinal cord and into the nerves of the penis. The nerve endings in the penis release chemical messengers called neurotransmitters that signal the corpora cavernosa (the two spongy rods of tissue that span the length of the penis) to relax and fill up with blood. As the penis becomes congested with blood, it enlarges and stiffens, causing an erection.
Surgical operation can wound nerves and arteries close to the penis making man an impotent. Also, between 35 and 50 percent of men with diabetes experience impotence. Many common medicines produce impotence as a side effect. Injury to the penis, spinal cord, prostate, bladder, and pelvis can lead to impotence by harming nerves, smooth muscles, arteries, and fibrous tissues of the corpora cavernosa. Other possible causes of impotence are smoking, which affects blood flow in veins and arteries, and hormonal abnormalities, such as insufficient testosterone. Physicians believe that psychological factors cause 10 to 20 percent of cases of impotence. A small percentage of men experience sporadic and situational impotence.
Risk factors
Men with diabetes, smoking, taking drugs or older than 50 years of age are particularly at risk for impotence. For instance men with diabetes are at risk because of their high risk of both atherosclerosis and a nerve disease called diabetic neuropathy. Age seems to be a strong indirect risk factor in that it is associated with increased likelihood of direct risk factors, some of which are listed above. Some medications can contribute to impotence, as can some operations and radiotherapy treatments.
Years ago, the standard treatment for impotence was a penile implant or long-term psychotherapy. Today there are these popular methods: vacuum devices, oral drugs, locally injected drugs, and surgically implanted devices. Gene therapy for ED is now being tested in several centers and may offer a long-lasting therapeutic approach for ED. Because ED can take a toll on a man's self-esteem, sex therapy is increasingly being recommended as a form of treatment on its own or in combination with other medical remedies. If your impotence problems are caused by low levels of testosterone then hormone therapy can be given in the form of injections or patches. Testosterone substitution therapy may improve energy, mood, and bone density, increase muscle mass and weight, and heighten sexual interest in older men who may have deficient levels of testosterone. Psychotherapy can also be valuable to men who are trying to overcome non psychological impotence. Hydrotherapy (cool showers, for instance) can also be effective for ED.
Sildenafil
The most common ED treatment today is with the prescription drug sildenafil citrate, sold under the brand name Viagra. Perhaps the most publicized advance was the introduction of the oral drug sildenafil citrate (Viagra) in March 1998.
Impotence, often called erectile dysfunction, refers to the males inability to achieve or maintain an erection long enough to engage in sexual intercourse. Impotence is distinguished from sterility (inability to produce sperm adequate for reproduction). Impotence usually has a physical cause, such as disease, injury, or drug side-effects. Impotence can be treatable in all age groups.
