Calm before the spawn: Climate change and coral spawning
What's the point of setting up marine reserves to protect coral reefs from pollution, ship groundings and overfishing if climate change could cause far more damage? A study published this week in London in Proceedings of the Royal Society B provides the answer. view more (2009-11-04)
Opioids and cannabinoids influence mobility of spermatozoids
A PhD thesis from the University of the Basque Country has concluded that there are opioid and cannabinoid receptors in human sperm and that these influence the mobility of spermatozoid. view more (2008-06-23)
Thieving whale caught on video gives rare clues about hunting strategy, sound production
For decades scientists have been intrigued by the variety of sounds emitted by sperm whales, partly due to a popular theory that suggests that the sounds might contain information about the animals' size. view more (2009-05-22)
Study allays fears about the physical and psychological development of ICSI children
Lausanne, Switzerland: Children born with the help of intracytoplasmic sperm injection (ICSI) appear to be developing normally, despite earlier concerns about their physical and psychological development, according to American researchers. Dr Gianpiero Palermo, from the Center for Reproductive Medicine and Infertility at Cornell University, USA,... view more... (2001-07-01)
Study shows that genetic quality of sperm deteriorates as men age
New research indicates that the genetic quality of sperm worsens as men get older, increasing a man's risk of being infertile, fathering unsuccessful pregnancies and passing along dwarfism and possibly other genetic diseases to his children. view more (2006-06-06)
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... view more...

Link between beef consumption during pregnancy and reduced sperm quality in sons
New research has shown that women who ate a lot of beef while pregnant had sons who were more likely to suffer from poor sperm quality as adults, and it suggests that the growth promoters used in cattle may play a role in these men's reduced fertility. view more (2007-03-28)
US researchers find first conclusive evidence that lead is linked to male infertility
US fertility experts today (Thursday 6 February) published the first conclusive evidence that lead is linked to male infertility. A report in Europe's leading reproductive medicine journal Human Reproduction[1] concludes that exposure to lead damages sperm function and may be a contributory cause of unexplained male infertility.[2] The findings... view more...

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health. view more (2006-04-03)
Rise in ICSI cycles suggests infertility could be affecting more men than women
Infertility may be becoming more of a man's problem than a woman's problem according to new figures released at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-22)
Gene breakthrough heralds better prospect for malaria solution
Scientists have made a major breakthrough in understanding the genetics of the insect parasite that is being targeted by researchers as a way of preventing the spread of malaria. view more (2006-07-25)
2 studies: The first finds twins born after fertility treatment have a higher risk of problems
Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins view more (2009-05-21)
Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring
The science has long been clear that smoking causes cancer, but new research shows that children could inherit genetic damage from a father who smokes. view more (2007-06-01)
Why is Apert's syndrome so common when mutation rate is so low?
Aperts syndrome is a condition caused by a mutation that produces fused fingers and toes, and alters cranial development in affected children. view more (2007-08-28)
Mayo Clinic researchers recommend embryo transfer delay for at-risk women
Mayo Clinic researchers have determined a method to achieve the best results for the mother's health and birth of a live baby for women who undergo in vitro fertilization who demonstrate risk of ovarian hyperstimulation syndrome. view more (2006-10-25)
Not 1, but 2 kinds of males found in the invasive round goby
Scientists have found the existence of two types of males of a fiercely invasive fish spreading through the Great Lakes, which may provide answers as to how they rapidly reproduce. view more (2009-06-16)
Hot tubs hurt fertility, UCSF study shows
Exposure to hot baths or hot tubs can lead to male infertility, but the effects can sometimes be reversible, according to a new study led by a University of California, San Francisco urologist. view more (2007-03-05)
Newly discovered proteins in seminal fluid may affect odds of producing offspring
Seminal fluid contains protein factors that, when transferred from a male to a female at mating, affect reproductive success. This is true of many different animals, from crickets to primates. view more (2008-07-29)
A gas, Viagra and sex in plants - researchers at the Instituto Gulbenkian de Ci'™ncia have found a link
Viagra affects growth of the male sex organ of plants, by intensifying the effect of nitric oxide during plant fertilization. This discovery, made by the Plant Development team at the Instituto Gulbenkian de Ci'™ncia(IGC), in Portugal, will be published in Development, in June. The study, led by José Feij'³, takes a step further in... view more... (2004-05-11)
Black-footed ferrets sired by males that died 8 years ago
Two black-footed ferrets at the Smithsonian's National Zoo have each given birth to a kit that was sired by males who died in 1999 and 2000 view more (2008-09-03)
