| 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. |

| SEMEN MAKES YOU HAPPY |
| Semen makes you happy. That's the remarkable conclusion of a study comparing women whose partners wear condoms with those whose partners don't.
The study, which is bound to provoke controversy, showed that the women who were directly exposed to semen were less depressed. The researchers think this is because mood-altering hormones in semen are absorbed through the vagina. They say they have ruled out other explanations. |

| 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. |

| MEN REGAIN EVOLUTIONARY DRIVER’S SEAT. MUTATION STUDY CONFIRMS STRONG MALE-DRIVEN EVOLUTION AMONG HUMANS AND APES |
| Researchers from the University of Chicago have estimated that genetic mutations – the raw material for evolution – occur 5.25 times more often in males than in females. This discovery should lay to rest any doubts raised by recent studies questioning the dominant role males play in producing mutations for molecular evolution. |

| 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. |
|
| MEN HAPPY TO TAKE CONTRACEPTION |
| The first survey of Australian men's attitudes to hormonal contraception has found that an overwhelming majority would be prepared to shoulder the responsibility.
The researchers, from the Department of Obstetrics and Gynaecology at the Monash Medical Centre, asked the male partners of women who had recently given birth what contraceptives they used and how they felt about a male contraceptive hormone. |

| 'AAAS' SPEAKERS REPORT WORLDWIDE 'EPIDEMIC' OF OBESITY |
| Obesity, considered until recently to be an exclusively "Western" disease, now poses a serious threat to the health of developing nations, particularly children, say scientists studying this emerging "global epidemic of fat." |

| TANNING LAMPS MAY INCREASE RISKS OF SKIN CANCERS |
| Users of tanning lamps may have an increased incidence of skin cancers and younger users may be at greatest risk, report Dartmouth Medical School (DMS) researchers. |

| SMOKING INCREASES LIKELIHOOD OF IMPOTENCY |
| Men who smoke are more likely to suffer from erectile dysfunction than nonsmokers, reports an international group of impotency experts in the November issue of the Journal of Urology. |

| WEAK SPERM COUNT DOES NOT ALWAYS MEAN INFERTILITY, STUDY SAYS |
| The nation's most in-depth study of the quality of sperm in nearly 1,500 men shows that sperm counts previously thought to be abnormal do not always mean infertility. The University of Rochester Medical Center research is published in the November 8, 2001 edition of the New England Journal of Medicine. |

| GENES EXPLAIN WHY MEN ARE TALLER |
| Over 4cm of men's height is due to the combination of just two genes, according to a new study undertaken at the University of Melbourne.
The research, published in the Journal of Clinical Endocrinology and Metabolism this week, identifies one gene on chromosome 15 and one on the Y chromosome as contributors to height in men. These genes may also help explain why men are taller than women. |
|
| WAR OF WORDS. WHY WOMEN HAVE MORE REASON THAN MEN TO FEAR THE GOSSIP'S TONGUE |
| MOST women may be physically weaker than men, but they have a formidable weapon at their disposal: gossip. Nattering to each other in this way could be why women form such strong social bonds, says anthropologist Nicole Hess from the University of California at Santa Barbara. |
|
| ELDERLY WOMEN HAVE BETTER MENTAL ABILITY THAN MEN, DESPITE LESS FORMAL EDUCATION |
| Elderly women have a better mental function than men despite their lower level of formal education, conclude Dutch researchers in the Journal of Neurology, Neurosurgery and Psychiatry. These findings challenge the view that a limited formal education is associated with lower mental ability and suggest that biological differences between men and women may be an alternative explanation. |

| HOW A WOMAN CHOOSE A MAN TO LIVE WITH |
| What makes a woman to keep fidelity to the man she chose to live with or, visa-versa, revising her choice, seeking a matching partner again and again? According to the GEO magazine, a partial answer to this question puzzling many people was given through a research on animals conducted by Swiss scientists. The outcomes of their research force us to differently look at the physiology of a man and his partner-searching strategy.

| HOW BUSINESSMEN AND BUSINESSWOMEN RESPOND ON CRITICISM |
| Good criticism is a gift for a man it’s addressed. If this man understands his mistakes and demerits, he will never do them once again.
It was found that women, on the contrary to men, more seriously accept criticism targeted at them, and take it into account as a good experience.
This situation happens because women, stepping up in the career hierarchy, have to overcome obstacles laid by men who think that there is no room for women in business. Therefore, increased requirements women face make them carefully take into account all their mistakes and demerits. Otherwise, women will not be able to compete with men dominating in business. |

| ACTIVE LIFESTYLE POSITIVELY INFLUENCES MAN'S SEXUAL ACTIVITY |
| Scientific researches have proved that those men who actively move every day have an increased sexual potency. Besides, additional daily "burning out" of up to 200 Kcal delays earlier impotency development. |
