NEW YORK (Reuters Health) - Sperm extraction is unlikely to be successful in men with a chromosomal disorder known as Klinefelter's syndrome who are over 35 years of age, Japanese investigators have found. "If the diagnosis is Klinefelter's syndrome, testicular sperm extraction should be performed before the critical age of 35 years," Dr. Hiroshi Okada, from Teikyo University School of Medicine in Tokyo, and colleagues write in the journal Fertility and Sterility. Men with...

By Amy Norton NEW YORK (Reuters Health) - Sperm banking may not only preserve young cancer patients' ability to have children, but their emotional well-being as well, according to Japanese researchers. They found that among 51 young men who banked their sperm before undergoing chemotherapy, 80 percent said that the move helped them in the "emotional battle against cancer." Even those who were unsure whether they wanted to have children in the future gained some peace of mind from...

But the benefits will take time to realize, experts predict The announcement this week that South Korean researchers have created the world's first cloned dog is being hailed as a scientific marvel, but one without immediate medical benefits -- for dogs or humans. And although the canine genome is far more complex than any other animal cloned to date, it doesn't bring the world closer to the ethically and emotionally charged possibility of cloning a human, experts said. Yet the breakthrough...

Findings have implications for middle-aged, wanna-be dads HealthDay News -- Older men have much more sperm DNA damage than young men do, which reduces their chances of fathering children, a Canadian study finds. The study of over 2,100 men found that injury to sperm DNA was significantly higher in men over 45 years old than in all younger age groups. Men over 45 years had double the sperm DNA damage compared with men younger than 30 years old. The research was presented Tuesday at the annual...

Copenhagen, Denmark: Reproductive tourism is on the increase in Europe, but rather than condemning it, we should regard it as a "safety valve" that helps us to avoid moral conflict, according to a European ethics expert. Guido Pennings, professor of ethics and bioethics at the University of Ghent, Belgium, told the 21st annual conference of the European Society of Human Reproduction and Embryology today (Monday 20 June) that thousands of people travelled between European countries each year,...

Copenhagen, Denmark: Scientists in the UK have proved that human embryonic stem cells can develop in the laboratory into the early forms of cells that eventually become eggs or sperm. Their work opens up the possibility that eggs and sperm could be grown from stem cells and used for assisted reproduction, therapeutic cloning and the creation of more stem cells for further research and for the improved treatments for patients suffering from a range of diseases. Behrouz Aflatoonian will tell...

ANN ARBOR, Mich. - A new technique might allow women diagnosed with cancer the opportunity to have children when chemotherapy and radiation treatments rob them of their fertility, researchers at the University of Michigan Comprehensive Cancer Center have found. By having her eggs frozen before she begins cancer treatments, a woman can preserve the hope of one day having a baby. Freezing eggs is one thing; thawing them safely so they can lead to pregnancy is the challenge. In the past,...
