Acupuncture may hold promise for women with hormone disorder
Charlottesville, Va., Sept. 3, 2008 -- Getting pregnant with her first child was difficult, but when Rebecca Killmeyer of Charlottesville, Va. experienced a miscarriage during her second pregnancy, she wasn't sure if she would ever have another baby. When she decided to enter a study testing the impact of acupuncture on women with polycystic ovary syndrome (PCOS) at the University of Virginia Health System, she came out with a miracle.

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.

There, we have seen more than 3 million babies born as a result of IVF and, in some countries, as many as 4 per cent of all babies born conceived by modern fertility techniques.

In birds, expecting to mate leads to higher fertilization rates
From an evolutionary perspective, the primary task of an organism is to pass along its genes to future generations. Such genetic transmission is usually assumed to be instinctive. 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
Researchers at UC San Diego and UC Irvine have found evidence that supports the theory that reproductive competition during the evolution of primate species has occurred at the level of sperm cell motility. In a paper published online by the Journal of the Royal Society Interface, a team led by Michael Berns, an adjunct professor of bioengineering at UCSD and a professor of biomedical engineering at the Beckman Laser Institute at UC Irvine, and UCSD Ph.D. candidate Jaclyn Nascimento reported that sperm cells from the more promiscuous chimpanzee and rhesus macaque species swim much faster and with much greater force than those of humans and gorillas, species where individual females mate primarily with only one male during a reproductive cycle.
