Should embryos with a hereditary disorder be transferred if no unaffected embryos are available?
Barcelona, Spain: The numbers of cycles of preimplantation genetic diagnosis or screening are rising steadily in Europe with over 2,700 reported in 2004 (the most recent year for which data are available). Fertility centres are able to screen for a growing number of genetically related conditions, but what should doctors do if no embryos without the targeted condition are available for transfer and the parents request that affected embryos should be transferred instead?

'Cancer was one of the best things to happen to me... but I worry about the future'
London, UK: For Dan Savage, surviving testicular cancer has been a spur to him making the most of his life and taking more adventurous decisions, and he says, that in retrospect, it was probably one of the best things that has happened to him. But as he approaches the end of his fifth year in remission from the disease, when he will be signed off as cured by the medical profession, he worries that from now on he will have no regular medical checks that might pick up early signs of the cancer returning. It will be down to him to contact the cancer clinic if he is worried about any new symptoms.

Prenatal biochemical screening only detects half of chromosomal abnormalities
Barcelona, Spain: Prenatal biochemical screening tests are widely used to look for chromosomal abnormalities in the fetus which can lead to serious handicap, or even death during gestation or in the first few days after birth. But these tests are only able to detect fewer than half of the total chromosomal abnormalities in the fetus, a scientist will tell the annual conference of the European Society of Human Genetics tomorrow (Monday 2 June) Dr. Francesca R. Grati, of the TOMA Laboratory, Busto Arsizio, Italy, says that these findings mean that women should be better informed on the limitations of such diagnostic tests.

WHI follow-up study: Risks of long-term hormone therapy continue to outweigh benefits
New results from the Women's Health Initiative (WHI) confirm that the health risks of long-term use of combination (estrogen plus progestin) hormone therapy in healthy, postmenopausal women persist even a few years after stopping the drugs and clearly outweigh the benefits. Researchers report that about three years after women stopped taking combination hormone therapy, many of the health effects of hormones such as increased risk of heart disease are diminished, but overall risks, including risks of stroke, blood clots, and cancer, remain high. The WHI is sponsored by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH).

Media availability: low-fat dietary pattern may lower risk of ovarian cancer
A diet low in fat could reduce the risk of ovarian cancer in healthy postmenopausal women, according to new results from the Women’s Health Initiative (WHI) Dietary Modification Trial. Researchers found that after four years, women who decreased the amount of dietary fat they consumed were 40 percent less likely to develop ovarian cancer than women who followed normal dietary patterns. As expected, no effect was found during the first four years because preventive benefits on cancer often take many years to develop. Ovarian cancer affects about 1 in 60 U.S. women in their lifetimes and has the highest mortality of all cancers of the female reproductive system.

However, a new study shows that species also learn to adapt to their surroundings in order to increase their “reproductive fitness”— the likelihood that they will successfully reproduce.

Primate sperm competition: speed matters
