Work-related Stress Can Trigger Erectile Dysfunction

A new study has shown that one in every ten men experience erectile dysfunction as a result of work-related stress. The same study also revealed that one in five men suffer a loss of sexual libido. This suggests that 90% of men have shown at least one clinical feature of stress due to work but only 54% know that stress from work may be the cause of their sexual condition.

Stress, either from work or at home, is known as one of the common cause of ED because it is associated with low testosterone levels.

Unfortunately, only 44% of men with this condition won't go to their doctors for consultation. The majority of those who do consult professional help in dealing with this problem only do so after 17 months of their first symptom.

One of the researchers who conducted the study said that work-place stress clearly has a strong impact on the incidence of erectile dysfunction in men. Men should think about the underlying cause of their ED, including how to combat their stress levels; not staying too late at work, a balanced and healthy diet, and regular exercise.

Lack of Sleep May Increase Chances of Death on Old Men

A new study conducted at the University of Minnesota revealed that disrupted rest and activity rhythms can be associated with the increased mortality rates among older men. Th study suggests that waking early, staying up late and severely disturbed sleep patterns on older men may have a detrimental impact on their health.

The experiment involved about 3,000 men older than 67 and they were tested for rest and activity biological rhythms using a device called an actigraph which they wore on heir wrists. This device tracked participants' movements, including the peak times of rest and activity, as well as the robustness of the activities for 24 hours a day for almost two years. Results showed that men who had peak activity times that were the earliest or latest, in comparison with the group average, had muhc greater risk of death.

Among the 3,000 participants, 180 died since the study begun.

"It's important to have a regular routine of waking and going to sleep," said Misti Paudel, M.P.H., principal investigator of the study and a member of the School of Public Health. "A good night sleep is important."

This is the first study to report strong associations between disturbed rest and activity rhythms and mortality rates in older men, who are still living in their homes (not institutionalized) - however, studies in cancer patients as well as institutionalized Alzheimer's patients have reported similar findings.

Lack of sleep can lead to a number of problems in older adults including depression, memory problems, and decreased attentiveness, and also can lead to serious health problems such as an increased risk of obesity, cardiovascular disease, and diabetes.

Another key study finding is that men with more robust rest/activity rhythms had much lower mortality rates. Having greater levels of activity during the day and/or lower levels of activity during the night (better sleep quality) are characteristics of robust rhythms.

Insulin-like Hormone May Prolong Life For Men

A recent study published in the Journal of Clinical Endocrinology and Metabolism stated that elderly men with higher activity of the hormone IGF-1 or insulin-growth factor 1 appear to have greater life expectancy and reduced vascular risk. This new finding came as a result of a new form of testing for IGF-bioactivity.

IGF-1 is a hormone similar in molecular structure to insulin, which is being released by the liver and plays an important role in childhood growth and continues to have anabolic effects on adults.

The study evaluated 376 healthy elderly men between the age of 73 and 94 from which the researchers took serum sample from. The participants are then contacted for eight years about their health status. Subjects with the lowest IGF-1 function had significantly higher mortality rate than subjects with the highest IGF-1 bioactivity. These results were especially significant to those who have high risk to die from cardiovascular complications.

Researchers in this study used a new method, a bioassay, to measure the function of IGF-1 in the blood. Compared to commonly used methods to measure IGF-1, the IGF-1 bioassay gives more information about the actual function (bioactivity) of circulating IGF-1 in the body. Determination of IGF-1 function using the bioassay opens the possibility to gather new insights about the functions of IGF-1 in the body
