Varicocele Treatment Does Not Improve Male Fertility
Authors of a systematic review in this week's issue of THE LANCET highlight how a common treatment for impaired male fertility may well be ineffective. Up to 15% of men are thought to suffer from varicoceles-dilation of veins in the scrotum-which sometimes leads to lower fertility because of decreased sperm quality and quantity arising from... view more...

Motion that powers sperm provides key to unravelling rare genetic disorder
Malfunction of the motor that powers sperm plays havoc with more than fertility: it may also be the root cause of the rare genetic disease Bardet-Biedl syndrome (BBS). Reporting in the journal Cell tomorrow, researchers from the UK, US and Canada reveal they have discovered a novel gene for BBS that's necessary for the generation of a cell's cilia... view more...

Smithsonian scientists working to save microscopic threatened species
The Smithsonian's National Zoo recently acquired 12,000 new animals-microscopic Elkhorn coral larvae harvested by National Zoo scientists in Puerto Rico-as part of an international collaborative program to raise the threatened species. view more (2007-09-27)
Teenage Boys Exposed To Environmental Pollutants Less Likely To Produce Male Children (p143)
A research letter in this week's issue of THE LANCET provides further evidence that adolescent boys exposed to organic pollutants are less likely to father a male child in adulthood. Investigators from the National Cheng Kung University Medical College, Taiwan, and the London School of Hygiene and Tropical Medicine, UK, studied the sex of over... view more... (2002-07-10)
UK researchers raise hopes of preserving fertility for women with cancer
UK fertility experts have sounded a note of cautious optimism about the safety of preserving ovarian tissue and transplanting it back into women after cancer treatment. The optimism follows research reported today (Thursday 27 September) in Human Reproduction*, Europe's leading journal of reproductive medicine. It is the first reported non-test... view more...

GUMC Researchers Show Adult Human Testes Cells Can Become Embryonic Stem-like, Capable of Treating Disease
Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from adult testes and have converted them back into pluripotent embryonic-like stem cells. Researchers say that the naïve cells are now potentially capable of morphing into any cell type that a body needs, from... view more... (2009-03-24)
Research sheds light on cause of Down syndrome and other genetic disorders
Scientists have a better understanding of what causes an abnormal number of chromosomes in offspring, a condition called aneuploidy that encompasses the most common genetic disorders in humans, such as Down syndrome, and is a leading cause of pregnancy loss. view more (2009-07-20)
Physician-Scientists Seek Solutions to Reproductive Problems Related to Chromosomal Variations
Approximately one in every 500 to 650 baby boys is born with an extra X chromosome, a variation in their genetic code that until a few years ago was thought to result in infertility in all cases. view more (2007-12-20)
First frozen egg baby born in Canada
The McGill University Health Center (MUHC) in Montreal is pleased to announce the first successful birth in Canada resulting from frozen eggs. view more (2005-05-30)
Tool developed to silence genes in specific tissues using RNAi
Researchers at The University of Texas M. D. Anderson Cancer Center say they have jumped a significant hurdle in the use of RNA interference (RNAi), believed by many to be the ultimate tool to both decode the function of individual genes in the human genome and to treat disease. view more (2006-01-17)
Penn Researchers Identify First Sex Chromosome Gene Involved in Meiosis and Male Infertility
A team of scientists led by University of Pennsylvania veterinary researchers have identified a gene, TEX11, located on the X chromosome, which when disrupted in mice renders the males sterile and reduces female fecundity. This is the first study of the genetic causes of infertility that links a particular sex chromosome meiosis-specific gene to... view more... (2008-03-17)
Italy now faces worldwide storm of protest over fertility proposals
Italian legislators now face worldwide condemnation by fertility experts for IVF proposals that could encourage multiple pregnancies and put babies at risk. The International Federation of Fertility Societies (IFFS) has added its voice to that of the European Society of Human Reproduction and Embryology, who have already described the proposals as... view more...

New study shows greenback cutthroat trout involved in recovery effort misidentified
A new study led by the University of Colorado at Boulder indicates biologists trying to save Colorado's native greenback cutthroat trout from extinction over the past several decades through hatchery propagation and restocking efforts have, in most cases, inadvertently restored the wrong fish. view more (2007-09-06)
Origen publishes in Nature a robust and versatile method for creating transgenic chickens
Origen Therapeutics announced today that it has succeeded in developing a robust and versatile technology for genetically modifying chickens that, for the first time, puts avian transgenics on a par with transgenic mice. view more (2006-06-08)

New study suggests winter babies face socioeconomic disadvantages
Many of us may often feel that we've been born under an unlucky sign. Now, new research by a pair of University of Notre Dame economists suggests that some of us are, in fact, born in an unlucky season. view more (2009-01-08)
In spiders, size matters: Small males are more often meals
Female spiders are voracious predators and consume a wide range of prey, which sometimes includes their mates. view more (2008-09-11)
First evidence that genetic imprinting occurs at earliest stage in test tube-matured eggs
Madrid, Spain: New research indicates that attempts to mature ovarian follicles in the laboratory may hit a stumbling block unless better 'growing' conditions can be identified. A French team[1] of fertility experts has revealed for the first time that maternal genetic imprinting errors can occur at the very earliest stages of egg follicle... view more... (2003-06-27)
Green tea component may help preserve stored platelets, tissues
In two separate studies, a major component in green tea, epigallocatechin-3-O-gallate (EGCG), has been found to help prolong the preservation of both stored blood platelets and cryopreserved skin tissues. view more (2009-09-14)
Obesity linked to hormone imbalance that impacts sexual quality of life
Hormonal changes and diminished sexual quality of life among obese men are related to the degree of obesity, and both are improved after gastric bypass surgery according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2009-03-03)
