Use eggs, not embryos, to derive stem cells, say researchers
Concerns about the ethics of using embryos created to treat infertile couples for stem cell research is discussed by researchers at St Mary's Hospital, Manchester in this week's BMJ. Although the Human Fertilisation and Embryology Act 1990 allows the creation of embryos for research in the United... view more (2003-10-08)

First study to show that when counting frozen as well as fresh embryos, single embryo transfer does not reduce the chances of having a baby
Doctors in Australia have found that transferring one embryo instead of two during an IVF cycle does not reduce the chances of a woman having a baby, when frozen as well as fresh embryos are taken into account. Dr Jim Catt, Embryology director of Sydney IVF, Australia, and his colleagues have... view more (2003-06-27)

What to do with leftover embryos in fertility clinics?
The majority of infertility patients are in favor of using left-over embryos for stem cell research and would also support selling left-over embryos to other couples, according to a recent survey.   view more (2008-09-25)

'Rhythm method' may kill off more embryos than other methods of contraception
The "rhythm method" may kill off more embryos than other contraceptive methods, such as coils, morning after pills, and oral contraceptives, suggests an article in the Journal of Medical Ethics.   view more (2006-05-25)

Significant differences in growth of male and female embryos after ICSI
There is a clear difference in growth rate between male and female pre-implantation embryos created by ICSI, but not after IVF, a scientist said today at the 20th annual conference of the European Society of Human Reproduction and Embryology.   Dr John Dumoulin, of the Academic... view more (2004-06-29)

Choosing healthy embryos in IVF
A revolutionary method for detecting which human embryos are most likely to develop successfully to the stage at which they implant in the womb has been developed by scientists at the University of York and clinicians at Leeds General Infirmary. The research has been funded by the Medical Research... view more (2002-05-07)

Procedure predicts embryos most likely to result in pregnancy
To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births... view more (2007-03-19)

PGD could save women from the agony of repeated miscarriages
Women who suffer repeated unexplained miscarriages can be helped to have babies if preimplantation genetic diagnosis (PGD) is carried out on their embryos before they are placed in the womb. Ms Carmen Rubio told the European Society of Human Reproduction and Embryology annual conference in Vienna... view more (2002-06-29)

Nuffield Council On Bioethics Concerned About Amendments To EU Directive On Tissues & Cells
The Nuffield Council on Bioethics has written to MEPs expressing concern about proposed amendments to the European Directive on tissues and cells, due to be discussed in the European Parliament next week (15 - 18 December). The proposals could restrict or even ban the creation of embryos for... view more (2003-12-11)

More than half of infertile couples may be willing to donate unused embryos to stem cell research
In a survey of over a thousand patients who have created and frozen embryos as part of fertility treatment, 60 percent said they would be likely to donate unused embryos for stem cell research.   view more (2007-06-21)

Fossilised Embryos - 500 Million Years Old
Evidence from fossilised embryos of worm-like creatures that lived 500 million years ago shows that embryos developed then in much the same way as their living relatives do today. The implications of this remarkable discovery, reported in this week's issue of Nature, is that embryological processes... view more (2004-01-12)

Embryo fossils reveal animal complexity 10 million years before Cambrian Explosion
Fossilized embryos predating the Cambrian Explosion by 10 million years provide evidence that early animals had already begun to adopt some of the structures and processes seen in today's embryos, say researchers from Indiana University Bloomington and nine other institutions in this week's Science.   view more (2006-10-13)
