Baldness 'could be good for your health' say scientists

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. Psm.2011.09.1933_fig5.jpg (719×1417) %20Sperm Quality Linked to Dietary Fat - in Urology, General Urology from MedPage Today.

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. Attaman, MD, of Dartmouth-Hitchcock Medical Center in Lebanon, N.H., and co-authors. Testosterone May Help Depressed Men, American Longevity Center Confirms.

Testosterone May Help Depressed Men, American Longevity Center Confirms

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. Science of the orgasm. AS they seek to document and demystify one of life's great thrills, scientists have run across some real head-scratchers.

Science of the orgasm

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. 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.

Penis length: Research find new way to measure penis length

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. Tae Beom Kim, a urologist at Gachon University in Incheon, Korea, and his colleagues studied 144 men over the age of 20 who were undergoing urological surgery for conditions that do not affect the length of the penis. One member of the team carefully measured the lengths of the index and ring fingers on the subject's right hand before surgery -- left hands are thought to be more variable.

Although it may seem like the results are coming out of left field, they actually are not. Men and women are what is termed sexually dysmorphic in terms of finger lengths. Relationships: Better Sex. It's been well documented that married people have sex more often than single people do.
