Microfluidics can be used successfully for IVF in mice

Technology that more closely mirrors the natural fertilization process is showing promise as a new method of in-vitro fertilization, researchers at the University of Michigan Health System have found.

Dengue and other viruses may have developed tricks that let them reproduce inside macrophages

A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. Instead, the antibody somehow stops the infectious process at a later point.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

Status and reproduction in humans: New evidence for the validity of evolutionary explanations

Men holding high positions within a hierarchical organisation have more offspring than those in other positions within the same organisation.

Approximately 25 percent of how a person ages is inherited from parents

According to professor Thomas Kirkwood of the University of Newcastle, there is no single gene for ageing. Throughout time, Humans have used energy to get food, produce offspring and survive danger - not to repair and maintain cells. So the maintenance system in the body slowly breaks down.

Workshop - stem cells in reproduction and in the brain

"Once we have found the factors by which body cells can be re-programmed into stem cells, then therapeutic cloning might become superfluous," said Hans R. Scholer, director of the Max Planck Institute for Molecular Biomedicine in Munster, Germany, at an international scientific symposium on stem cell research in Kobe, Japan.

Putting the risk of breast cancer and postmenopausal Hormone Therapy (HT) into perspective

Two similar comprehensive literature reviews and an editorial about the varying risk with different postmenopausal hormone therapy regimens have been published this month in Human Reproduction Update.

New key evidence supports claims that some types of cancer originate with defects in stem cells

Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg and the Institute of Biomedical Research of the Parc Científic de Barcelona (IRB-PCB) have now added key evidence to claims that some types of cancer originate with defects in stem cells.

C. elegans worm provides clues to dealing with human disease

A step towards understanding cell mutations that cause a variety of human diseases, particularly in children -- including that which brings about premature aging and early death -- has been taken by researchers at the Hebrew University of Jerusalem Silberman Institute of Life Sciences and the John Hopkins University School of Medicine.

Human Y chromosome stays intact while chimp Y loses genes

The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates, new research indicates.

Charles Darwin was right and chimp gene map proves it

According to scientists who have mapped the complete chimp genome and compared it to the human gene map, there is little genetic difference between humans and chimps, but those differences count for a lot.

Sperm testing in UK labs fails to meet World Health Organization standards

Teams from the Universities of Bristol and Sheffield found only five per cent of the clinics met all WHO standards for assessing the size and shape of sperm.

Severely restricting calories over decades won't dramatically extend life span

Severely restricting calories over decades may add a few years to a human life span, but will not enable humans to live to 125 and beyond, as many have speculated, evolutionary biologists report.

How germ cells decide whether to be sperm or eggs

Johns Hopkins biologists have determined how developing embryos tell their specialized "germ cells" whether to develop into a male's sperm or a female's eggs.

Stress does not appear to influence the outcome of IVF

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.

Guidelines released to cover new embryo donation option for infertile couples

Surplus embryos created by couples who have undergone IVF treatment can now be donated to assist other infertile people have a child, as a result of new guidelines released in New Zealand.

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

Australian stem cell discovery hailed as a major medical and scientific development

Monash Institute of Medical Research (MIMR) senior scientist Dr Caroline Gargett's discovery of adult stem cells in the uterus that can be grown into bone, muscle, fat and cartilage, has been hailed as a major medical and scientific development by international reproduction experts.

Fertility drugs may be ineffective for women who lack a gene called the estrogen receptor beta

"What we found is that the beta estrogen receptor plays a role in moving the egg outside the ovary so it can be fertilized," said Kenneth Korach, Ph.D., Laboratory Chief at the National Institute of Environmental Health Sciences (NIEHS) where the research was conducted. "We never knew before what function this receptor played in reproduction."
