Time-lapse recordings reveal why IVF embryos are more likely to develop into twins
Lyon, France: Evidence gathered from time-lapse recordings of the formation of early embryos (blastocysts) in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. Furthermore, the research has shown that the culture in which the IVF embryos are formed is possibly responsible for th...Children born after PGD as healthy as those born after conventional IVF treatment
... PGD is a new option for couples at risk of transmitting genetic di...Ultrasound could help couples undergoing IVF
... Research published today in Reproductive Biology and Endocrinology details how Janet Kwee et. al. from Vrije Universiteit Medical Centre in Amsterdam, The Netherlands studied 110 women aged 18-39 who had difficult...Mouse stem cell line advance suggests potential for IVF-incompetent eggs
Researchers have found that mouse oocytes that fail to become fertilized during in vitro fertilization are nevertheless often capable of succeeding as "cytoplasmic donors" during a subsequent cloning step using so-called nuclear transfer. Although the implications for human eggs are not yet clear, the findings are of interest because of the ethical and practical concerns surrounding the need for...IVF identity fraud: A phenomenon that puts patients, children, and clinics at risk
Safeguards against identity fraud by IVF patients are needed in order to prevent impostors gaining access to treatment, a scientist told the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic, onTuesday 20 June 2006. Dr.Luca Sabatini, from the Centre for Reproductive Medicine at St. Bartholomew's Hospital, London, UK, said that research...How IVF could be causing genetic errors in embryos
Prague, Czech Republic: The conditions in which embryos are cultured in the laboratory during in vitro fertilisation could be causing genetic errors that are associated with certain developmental syndromes and other abnormalities in growth and development, such as low birth weight....... Researchers told the 22nd annual conference of the European Society of Human Reproduction and Embryology today...First study to show IVF single embryo transfer as successful as double transfer in older women
Research by fertility experts in Finland has demonstrated for the first time that in many cases transferring a single embryo to the womb in women undergoing IVF is just as likely to result in pregnancy and a live birth in those aged 36 to 39 as it is in younger women....... Their study indicates that it is the quality of the embryo that is more important in determining the success of IVF rather t...Slight increased risk of major birth defects associated with IVF
Babies conceived through in vitro fertilization (IVF), a method of assisted reproduction, have a slightly increased risk of major birth defects, such as heart or muscle and skeletal defects, compared to babies conceived naturally, according to a University of Iowa study. ...... The risk for IVF babies was 6.2 percent compared to 4.4 percent for naturally conceived babies. While the finding sugges...New research shows no link between stress and chances of IVF success
New research from Sweden has shown that psychological stress does not appear to influence the outcome of IVF good news for women who fear that the understandable anxiety that they suffer during fertility treatment might damage their chances of conceiving....... "This means that we can use these findings to reassure women and this information should, in itself, help to reduce their stress and wor...Study is first to show side-stream smoking is as damaging to IVF success as being a smoker
It has been known for some time that smoking can affect a woman's fertility, but Canadian research published (Thursday 26 May) in Europe's leading reproductive medicine journal Human Reproduction - is just as damaging.... ...In a study of women undergoing IVF or ICSI , researchers from McMaster University and Hamilton Health Sciences, in Hamilton, Ontario, examined the quality of embryos and the...Research shows smoking adds a decade to reproductive age of IVF patients
A major new Dutch study has found that smoking adds the equivalent of ten years to a 20-year-old subfertile woman's reproductive age and has a "devastating" impact on a couples' chances of having a live birth after IVF. Being overweight also seriously damages their chances. ......The harmful effects of smoking or being overweight were strongest among those women who had no obvious cause for not c...THE lack of natural growth factors in the fluid in which IVF embryos are grown could have lifelong effects on people conceived this way. That is the implication of a study on mice by Australian researchers, who say preliminary studies of human embryos back their claims. Although the latest review of IVF safety found no differences between 8-year-olds conceived normally and those conceived by IVF...
