Testicular cancer Testicular cancer is the most common cancer for men aged 15-34. This type of cancer is 40 times more likely to occur in men whose testicles have not descended into the scrotum or did so after the age of 6. This type of cancer is usually found by men themselves, and it is very curable if caught early. The best way to protect yourself is to do a monthly testicular self-exam and to have your physician check for testicular abnormalities during an annual physical exam.

Erectile dysfunction

Among the various sexually related problems a man can face, erectile dysfunction (ED) is arguably the most traumatic. To many men, their ability to perform sexually is an integral part of their self-image, and to not be able to perform in this domain is an insult to their "manhood". It is estimated that ED regularly affects 34% of men in Canada and that less than 10% of them seek treatment. Of course, since the approval of the anti-impotence drug Viagra by Health Canada, the number of men seeking treatment has greatly increased, but many still don't seek help.

Causes of erectile dysfunction

Although ED is more common in older men, younger men are also affected. It is reported that 50 to 80% of ED is related to physical causes, but many of those with physical causes also experience psychological effects, which further intensify the problem. Many physical causes of ED have been identified. They include: disruptions in blood flow in the penis (such as that caused by the narrowing of blood vessels, also known as atherosclerosis); nerve damage; decreased or low testosterone levels; diabetes; alcoholism; liver or kidney failure; multiple sclerosis; and stroke. Many prescription medications such as antidepressants, tranquillizers and high blood pressure medication, can contribute to ED. Men who smoke are at a greater risk of experiencing ED. Erectile dysfunction can also be caused by psychological factors. One of these factors is how a person feels about sex. If a man is nervous about sex, has had bad experiences with sex or a previous bout of ED, these can affect his ability to achieve a sufficient erection.

Premature ejaculation

The inability to achieve or maintain an erection can be very distressing for a man, but so can premature ejaculation. Premature ejaculation occurs when a man ejaculates too quickly during sex with a partner, leaving the partner sexually dissatisfied. This can happen to a man at any age, but it is more common in younger men. Unlike erectile dysfunction, where there is often an underlying physical problem, there is nothing wrong with the anatomy of a man who experiences premature ejaculation. Treating premature ejaculation involves gaining control over the ejaculatory process. . Performance enhancers

Caffeine

The claims made about caffeine suggest that it can improve endurance by helping the body burn fat and save carbohydrates for later. Several small studies show that caffeine can allow athletes to exercise longer. However, other studies have found little or no benefit. It has not been proven that caffeine helps burn fat.

Antioxidants (such as vitamin E and vitamin C)

The claims about antioxidants say that they limit damage done by free radicals that are released from vigorous exercise. Some studies indicate that large doses of some antioxidants may protect against damage caused by free radicals..

Amino acids

Those marketing amino acids claim that they can boost muscle growth and strength, since amino acids are the building blocks of proteins from which muscle is composed. The scientific evidence that amino acids can be any more effective than proteins in food is very weak.

Creatine

Creatine is produced in the body and replenishes compounds necessary to supply energy. Those promoting creatine supplements indicate that it will boost the amount of available adenosine triphosphate (ATP), which in turn supplies energy and allows for better performance.

Androstenedione

Androstenedione is another relatively new supplement on the market. There has been little research on its safety. It claims to boost testosterone levels in blood and, therefore, can help build muscle.
