Baldness 'could be good for your health' say scientists. A receding hairline can be a good thing, according to US scientists, who say men who go bald by 30 appear to be less likely to develop prostate cancer.
Researchers at the University of Washington School of Medicine studied 2,000 men aged between 40 and 47. They were able to link high levels of the male hormone testosterone in those who lose their hair earlier with a lower risk of tumours. The findings are published in the journal Cancer Epidemiology. Half of the men in this study had suffered prostate cancer. Researchers compared the rate of tumours in those who said their hair had thinned by the age of 30 with those who did not suffer hair loss.

Men who consumed large quantities of dietary fat had significantly lower sperm production and concentration than men who had lower fat intake, results of a clinical study showed.
Sperm count and concentration were about 40% lower in men whose diet derived 37% or more of calories as fat or 13% or more of calories as saturated fat, as compared with men who had less fat intake. The strength of the association increased after controlling for body mass index (BMI) and other lifestyle factors. Higher intake of omega-3 fatty acids was associated with better sperm morphology, investigators reported online in Human Reproduction. "Given the limitations of the current study, in particular, the fact that it is a cross-sectional analysis and that it is the first report of a relation between dietary fat and semen quality, it is essential that these findings be reproduced in future work," stressed Jill A.

NewsRx.com Miami, FL - American Longevity Center, an advanced anti-aging and proactive health clinic, says men who are unsuccessfully battling depression with prescription medicine should also have their testosterone levels checked.
Studies have shown dramatic improvements in men taking testosterone supplements along with anti-depressants (see also Depression). Testosterone is an essential hormone for men. Testosterone affects a man's attitude, his level of self-confidence, his energy and sex drive. When testosterone levels decline, and they begin to do so by about 1-2% each year by the time a man is in his mid-twenties, he can feel anxious, lethargic and depressed. A study conducted by Harvard Medical School's McLean Hospital showed that nearly half of the men who had not responded to conventional depression treatment had low or low-to-normal testosterone levels.

How, for example, can they explain the fact that some men and women who are paralyzed and numb below the waist are able to have orgasms? How to explain the “orgasmic auras” that can descend at the onset of epileptic seizures -- sensations so pleasurable they prompt some patients to refuse antiseizure medication? And how on Earth to explain the case of the amputee who felt his orgasms centered in that missing foot? No one -- no sexologist, no neuroscientist -- really knows. For a subject with so many armchair experts, the human orgasm is remarkably mysterious. But today, a few scientists are making real progress -- in part because they’re changing their focus. In an orgasm orchestra, the genitalia may be the instruments, but the central nervous system is the conductor.
Penis length: Research find new way to measure penis length. Penis length cannot be determined by how big his hands or feet are -- those and other supposed indicators have been widely discredited for years.
But now a team of Korean researchers has produced what may be a more reliable guide: the ratio of the length of his index finger to that of his ring finger. The lower that ratio, the longer the penis may be, the researchers wrote Monday in the Asian Journal of Andrology. Dr. Relationships: Better Sex. It's been well documented that married people have sex more often than single people do.
But it's not always great sex. If you're looking to recapture the manic sexual frenzy of your first months together, fuzzy handcuffs and herbal supplements just won't cut it.

The time-release version of this pill causes levels of melatonin in the blood stream to steadily rise instead of dumping it in all at once. The theory is that it will help you stay asleep, but trials have yet to find time-release tablets better or more effective than standard ones. Why you might need it: At night, the brain churns out increasing levels of melatonin, which makes you feel groggy and helps you nod off. For some people—especially travelers who experience jet lag and shift workers, though it sometimes occurs for unexplained reasons—your melatonin release may be disrupted, which can derail your ability to fall asleep.
What’s more, a recent study published in the journal Diabetes, Metabolic Syndrome, and Obesity: Targets and Therapy found that time-release melatonin may offer a one-two punch for type-2 diabetics with insomnia. The Best Smoothie Ingredients: Men.
