Italian study finds traffic pollution affects male fertility
A study by Italian researchers of motorway tollgate attendants has demonstrated that traffic pollution damages the quality of sperm in young and middle-aged men. In research published today (Wednesday 30 April) in Europe's leading reproductive medicine journal Human Reproduction[1] the research team from the University of Naples say their work... view more...

Romance, schmomance - Natural selection continues even after sex
Some breaking news, just in time for Valentine's Day: Researchers have identified something called 'sperm competition' that they think has evolved to ensure a genetic future. In sexual reproduction, natural selection is generally thought of as something that happens prior to - and in fact leads to - the Big Event. view more (2007-02-13)
First Cryopreservation Seed Bank For Arabica Coffee
The storage of coffee (Coffea arabica) seeds to ensure preservation of their genetic resources is an important problem. Like many other tropical plants, coffee seeds cannot be conserved in cold storage because they remain cold-sensitive. IRD (Institut de recherche pour le développement), with the financial backing of the BRG (Bureau des... view more... (2000-09-14)
CSHL scientists discover how 'companion' cells to sperm protect them from genetic damage
In plant pollen grains, sperm cells, which carry the genetic material to be passed on to progeny, are cocooned within larger "companion" cells that are called pollen vegetative cells. These companions provide sperm with energy and nourishment, and push them towards their targets during fertilization. view more (2009-02-06)
ICSI or IVF: Babies born from frozen embryos do just as well
Analysis of the longest running ICSI programme in the United States has found reassuring evidence that babies born from frozen embryos fertilised via ICSI (intracytoplasmic sperm injection) do just as well as those born from frozen embryos fertilised via standard IVF treatment. view more (2009-06-30)
For young boys with cancer, testicular tissue banking may be option to preserve fertility
For parents of children with cancer, the hopeful news is that pediatric survival rates have steadily improved for decades. Among the bad news-treatments that enable survival often cause infertility. view more (2009-11-10)
First research to show that diabetes damages DNA in men's sperm and may affect fertility
Scientists have found that sperm from diabetic men have greater levels of DNA damage than sperm from men who do not have the disease. They warn that such DNA damage might affect a man's fertility. view more (2007-05-03)
Size did matter
The mystery of giant sperm present in some living animal groups today has taken on a new dimension. In one group of micro-crustaceans new evidence shows the feature is at least 100 million years old. view more (2009-06-19)
Small RNAs can play critical roles in male infertility/contraception
University of Nevada School of Medicine scientists in the Department of Physiology and Cell Biology have discovered insight into the reproductive workings of the male sex chromosome that may have significant implications for male infertility and contraception. view more (2009-04-10)
Minimally invasive treatment helps infertile couples conceive
Couples struggling with infertility face uncertain odds when considering various treatment options. But a new study reveals that embolization, a minimally invasive treatment for arguably the most common cause of infertility in men, can significantly improve a couple's chances for pregnancy. view more (2006-11-29)
Treating male infertility with stem cells
New research has examined the usefulness of bone marrow stem cells for treating male infertility, with promising results. The related report by Lue et al, "Fate of bone marrow stem cells transplanted into the testis: potential implication for men with testicular failure," appears in the March issue of The American Journal of Pathology. view more (2007-03-02)
High levels of cycling training damage triathletes' sperm
The high-intensity training undertaken by triathletes has a significant impact on the quality of their sperm. view more (2009-06-30)
Presentation of the "Document on the Freezing of Oocytes for Human Reproduction"
The Observatory of Bioethics and Law has made public its latest "Document on the Freezing of Oocytes for Human Reproduction", which upholds the authorisation of the cryopreservation of oocytes for use in assisted reproduction. The Document was drawn up by the Opinion Group of the Observatory of Bioethics and Law of the University of... view more... (2002-05-07)
Good news and bad for dad this Father's Day
It was long believed that conception does not involve a meeting of equals. The egg is a relatively large, impressive biological factory compared with the tiny sperm, which delivers to the egg one copy of the father's genes. view more (2009-06-15)
Jumping genes discovery 'challenges current assumptions'
Jumping genes do most of their jumping, not during the development of sperm and egg cells, but during the development of the embryo itself. view more (2009-06-12)
US researchers sound warning note over postponing fatherhood - new findings confirm male fertility declines with age
Further evidence that men's fertility declines with age is reported today (Thursday 6 February) in Human Reproduction[1] - Europe's leading reproductive medicine journal. A study of 97 healthy non-smoking men aged from 22 to 80 has demonstrated that, as they age, men's semen quality declines. There was a continuous reduction in sperm motility... view more...

Unique study shows oil, gas seismic work not affecting Gulf sperm whales
Noise can be irritating and possibly harmful for everything from mice to humans - and maybe even 60-foot whales in the Gulf of Mexico. view more (2008-08-22)
Levels of folate in men's diets is linked to chromosomal abnormalities in their sperm
Researchers have found an association between a vitamin found in leafy green vegetables, fruit and pulses and levels of chromosomal abnormalities in men's sperm. Men who consumed high levels of folate (a water-soluble B vitamin that occurs naturally in food) and folic acid (the synthetic form of the vitamin) tended to have lower levels of abnormal... view more...

Air dried sperm could allow home storage
Madrid, Spain: A novel method of preserving sperm through air drying is showing initial promise and has the potential to revolutionize sperm storage, allowing men awaiting in vitro fertilization (IVF) to take care of their sperm at home. Dr Daniel Imoedemhe, a consultant in reproductive medicine and endocrinology, working in Saudi Arabia, told the... view more... (2003-06-28)
Minimally invasive treatment improves male fertility
A minimally invasive treatment for a common cause of male infertility can significantly improve a couple's chances for pregnancy, according to a new study published in the August issue of Radiology. view more (2008-07-22)
