Survivors of childhood cancer run particular risks when pregnant and should be closely monitored, the 25th annual conference of the European Society of Human Reproduction and Embryology heard this week.

Bioethicists lead call for public debates on future uses of stem cells

More than 40 scientists, bioethicists, lawyers and science journal editors are calling on their colleagues, policy makers and the public to begin developing guidelines for the research and reproductive use of stem cell-derived eggs and sperm, even though such use may be a decade or more away.

Reduced ovarian reserve is associated with an increased risk of trisomic pregnancy

Women who have a diminished number of eggs in their ovaries, either because they are older or for some other reason such as ovarian surgery, may be more at risk of a trisomic pregnancy than women with an ovarian reserve within the normal, fertile range.

Two studies on polycystic ovarian syndrome shed light on its causes and its effect on brothers of women with the condition

Researchers have found evidence that chronic disease in either a mother or father can create unfavourable conditions in the womb that are associated with the development of polycystic ovarian syndrome (PCOS) in daughters. In another study, researchers found that brothers of women with PCOS and insulin resistance are themselves at greater risk of developing insulin resistance or diabetes, suggesting that factors associated with the condition can be passed down to sons as well as daughters.

Frequent sex improves sperm quality

Daily sex (or ejaculating daily) for seven days improves men's sperm quality by reducing the amount of DNA damage, according to an Australian study presented today (Tuesday) to the 25th annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam.

New test detects genetic and chromosomal abnormalities in embryos - ready for clinical trials

One-step screening for both genetic and chromosomal abnormalities has come a stage closer as scientists announced that an embryo test they have been developing has successfully screened cells taken from spare embryos that were known to have cystic fibrosis.

Women with cystic fibrosis can have safe and successful fertility treatment

Women with cystic fibrosis can have fertility treatment to help them have babies without any long-term adverse effects on either themselves or their children, according to new research presented at the 25th annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam today (Tuesday).

Research shows it is possible to freeze embryos and reduce multiple pregnancies in PGD cycles without adversely affecting pregnancy rates

Transferring just one embryo at a time to a woman's womb after embryos have undergone preimplantation genetic diagnosis (PGD) and freezing at the blastocyst stage has become a real option after researchers achieved pregnancy rates that were as good as those for blastocysts that had not had a cell removed for PGD before freezing. Their results mean that it will be possible to reduce the number of multiple pregnancies after PGD and the consequent complications associated with these pregnancies.

First ever study of European patients shows large numbers crossing borders for reproductive therapies

A substantial number of European patients travel to other countries for fertility treatment, both because they think that they will receive better quality care abroad and in order to undergo procedures that are banned in their home country says a study of the subject launched at the 25th annual conference of the European Society of Human Reproduction and Embryology.

First baby born after new ovarian transplant technique

A new technique for transplanting the ovaries of women who have lost their fertility as a result of cancer treatment was outlined to the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June).

Intense cycling training damages sperm

The high-intensity training undertaken by triathletes has a significant impact on the quality of their sperm, the 25th annual conference of the European Society of Human Reproduction and Embryology heard today (Monday 29 June). Professor Diana Vaamonde, from the University of Cordoba Medical School, Cordoba, Spain, said that the triathletes who did the most cycling training had the worst sperm morphology.

New, less invasive genetic test greatly improves pregnancy rates in older women with poor prognosis

A new test examining chromosomes in human eggs a few hours after fertilisation can identify those that are capable of forming a healthy baby, a researcher told the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June).

Low dose bisphenol-A exposure shows significant reproductive health effects in rats

New research from North Carolina State University and the National Institute of Environmental Health Sciences (NIEHS) shows significant reproductive health effects in rats that have been exposed to bisphenol-A (BPA) at levels equivalent to or below the dose that has been thought not to produce any adverse effects.

New findings on how stress causes sexual dysfunction and infertility

University of California, Berkeley, researchers have found what they think is a critical and, until now, missing piece of the puzzle about how stress causes sexual dysfunction and infertility.

Dangerous liaisons: bacterial 'sex' causes antibiotic resistance

Some disease-causing bacteria are becoming resistant to antibiotics because they have peculiar sex lives, say researchers publishing new results today in the journal Science.

Social moms make better moms, at least in baboons

Female baboons who have strong social relationships with other females give birth to offspring who are much more likely to survive to adulthood than baboons reared by less social mothers, according to a new study by researchers at the University of Pennsylvania, the University of California, Los Angeles, and others.

Worldwide increase in assisted reproduction

Assisted reproductive technology (ART) is responsible for an estimated 219,000 to 246,000 babies born each year worldwide according to an international study. The study also finds that the number of ART procedures is growing steadily: in just two years (from 2000 to 2002) ART activity increased by more than 25%.
