| The increasing use of laptop computers could produce a generation of men with fertility problems, a new study suggests. |
|
| FREQUENT SEX KEEPS CANCER AT BAY |
| Men who have active sex lives or masturbate frequently have a reduced chance of developing prostate cancer, a U.S. study has shown. |
|
| ORAL SEX LINKED TO MOUTH CANCER |
| Oral sex has been linked to a tiny risk of mouth cancer, an international team of scientists say. |
|
| STONED SPERM TOO SPEEDY TO FERTILISE |
| Heavy marijuana users have sperm that move too fast, too soon, and become burnt out, reducing the chance of fertilisation, according to new U.S. research. |
|
| MALE CONTRACEPTIVE SUCCESS: NOW IT'S OVER TO INDUSTRY |
| A long-acting but reversible male contraceptive has been fully proven to protect against pregnancies, paving the way for its commercial development. |
|
| CAN MASTURBATING KEEP THE DOCTOR AWAY? |
| IT WILL make you go blind. It will make your palms grow hairy. Thankfully, such myths about masturbation are largely a thing of the past. But the latest research has even better news for young men: frequent self-pleasuring could protect against the most common kind of cancer. |
|
| WOMEN LIE ABOUT SEX |
| Surveys suggesting that men are more sexually active than women may be wrong because women are more likely to lie when answering questions about their own sexual activity, a clever new U.S. study has found. |
|
| MATE CHOICE: OPPOSITES DON'T ATTRACT |
| When it comes to finding the right partner in life, the old adage that 'opposites attract' is wrong, according to a new U.S. study. |
|
| WHAT WOMEN NEED: SWEATY MALE ARMPITS |
| Being exposed to the smell of a sweaty male armpit can make a woman feel calmer, according to a new study by a U.S. research team. |
|
| HIGH MEAT DIETS MAY POSE A KIDNEY RISK |
| People with even a mild kidney condition could damage them by taking up a high protein diet, a large-scale American study has found. |
|
| ALCOHOL'S EFFECTS ON TESTOSTERONE |
| Most research has shown that alcohol inhibits testosterone secretion in male animals and humans.
A new study has found that acute administration of alcohol can increase testosterone biosynthesis in some male rodents.
These results provide evidence for individual differences in behavioral reactions to alcohol. |
|
| RESEARCH REVEALS A CELLULAR BASIS FOR A MALE BIOLOGICAL CLOCK |
| Researchers at the University of Washington have discovered a cellular basis for what many have long suspected: Men, as well as women, have a reproductive clock that ticks down with age. |
|
| DIETARY CHANGE MAY PREVENT THE MOST SERIOUS FORM OF PROSTATE CANCER |
| A fat-laden diet and high calcium consumption are both well-known suspected risk factors for prostate cancer. However, new findings from the Fred Hutchinson Cancer Research Center suggest that fat and calcium themselves may not cause prostate cancer, as previously thought, but instead may fuel its progression from localized to advanced disease. |
|
| CAFFEINE MAY AFFECT FERTILITY |
| Men and women undergoing infertility treatment should re-think their coffee habit, recent evidence suggests. |
|
| BLADDER-SPARING PROCEDURE FOUND EFFECTIVE FOR TREATING INVASIVE BLADDER CANCER |
| For patients with the most serious form of bladder cancer, the standard of care has been to completely remove the bladder and adjacent organs. Now scientists at Massachusetts General Hospital (MGH) have shown that therapeutic strategies aimed at sparing the bladder have long-term cure rates just as good as does bladder removal. The findings, which appear in the July issue of Urology, could offer a better quality of life for many patients. |
|
| SMOKING DECREASES MEN'S CHANCES OF FATHERHOOD BY IVF AND ICSI |
| Men who smoke reduce their chances of successfully fathering a child by either standard IVF techniques or by ICSI, according to research carried out in Germany.
Dr Michael Zitzmann told the European Society of Human Reproduction and Embryology annual conference in Vienna that smoking altered the DNA of sperm and he believed this hampered the development of the embryo. |
|
| NEW STUDY FINDS VASECTOMY DOES NOT INCREASE PROSTATE CANCER RISK |
| Contrary to some earlier studies, a new study funded in part by the National Institute of Child Health and Human Development (NICHD) found that men who undergo vasectomies are no more likely to develop prostate cancer than are men who do not. |
|
| U OF MINNESOTA STUDY: ADULT BONE MARROW STEM CELLS CAN BECOME LIVER CELLS |
| Researchers at the University of Minnesota Stem Cell Institute (SCI) have demonstrated, for the first time, the ability of adult bone marrow stem cells to differentiate in vitro as hepatocytes (liver cells) with hepatocyte phenotype and function. The findings will be published in the May 15, 2002 issue of the Journal of Clinical Investigation. |
|
| IS FOLATE GOOD FOR BOYS TOO? |
| Folic acid and zinc may increase sperm counts in men with fertility problems, say Dutch researchers — but Australian experts are cautious about the results. |
|
| URINARY BLADDER GENE IS LINKED WITH AN INBORN DEFECT IN KIDNEY FUNCTIONALITY |
| Researchers of the New York Medical School University have discovered that human gene, which is responsible for an urinary bladder formation, may be a reason of an inborn defect that is the main reason of children’s kidney failure. |
