Embryology is the study of the development of an embryo. An embryo is defined as any organism in an early stage well before birth or hatching, or in plants, before germination occurs.

New British guidelines to protect the safety of frozen sperm, eggs and embryos

The Human Fertilisation and Embryology Authority, UK has announced strict new guidelines to protect the safety of frozen sperm, eggs and embryos stored at fertility clinics throughout the UK.

Cellular garbage plays a key role in the process of cytokinesis, or cell division

A cellular structure discovered 125 years ago and dismissed by many biologists as "cellular garbage" has been found to play a key role in the process of cytokinesis, or cell division, one of the most ancient and important of all biological phenomena.

Randomness in gene expression to lead to differences in people that are genetically identical

Experiments by Howard Hughes Medical Institute (HHMI) researchers have revealed it might be possible for randomness in gene expression to lead to differences in cells — or people, for that matter — that are genetically identical.

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals. The discovery was made by applying the latest laboratory methods to a strain of mice restored from embryos frozen since the early 70s.

Scientists have sped up a common jumping gene found in the human genome

Johns Hopkins scientists have transformed a common "jumping gene" found in the human genome into one that moves hundreds of times more often than normal in mouse and human cells.

Father's sperm packs more than just a fertilizer

The major function of a man's sperm was fertilization, scientists once thought. True, sperm contains the father's chromosomes; but new studies from Wayne State University show that RNAs critically important to early growth of an embryo are also delivered.

10 years of IVF procedures show frozen sperm as good as fresh

A review of the past ten years of In Vitro Fertilization (IVF) procedures at the Mayo Clinic revealed equivalent outcomes between frozen and fresh sperm for oocyte insemination, according to a new study unveiled today at the AUA’s Annual Scientific Meeting.

Scientists tackle the decline in male fertility

This week, Australian scientists will gather at The University of Queensland’s Institute for Molecular Bioscience (IMB) to discuss the causes of an alarming decline in male fertility in Australia and worldwide.

Researchers develop low-carb corn with enhanced protein and oil

Researchers at the University of California, Riverside reported the development of technology that doubles the protein and oil content of corn while reducing its carbohydrate content, a boost for growers to feed both people and livestock.

Scientists have discovered a genetic cause of cleft lip and palate in mice

By watching mice “dance” and comparing the DNA of the dancers to their flat-footed siblings, scientists have discovered a genetic cause of cleft lip and palate in mice, a finding that is already being used to search for a similar genetic defect in humans.

Japanese scientists have created a viable mouse derived from two genetic mothers with no contribution by a male animal

Japanese scientists have created a viable mouse derived from two genetic mothers with no contribution by a male animal.

Dolly the sheeps creators harbour no desire to clone humans

The Scottish institute that cloned Dolly the sheep wants to clone human embryos to study motor neurone disease.

Infertile couples may be unaware of multiple birth risks

Multiple births -- twins, triplets or more babies in one pregnancy -- have more risks of infant death and long-term disabilities such as cerebral palsy than births of single babies do. However, many couples seeking infertility treatments desire multiples and have poor knowledge particularly about the risks for twins, a University of Iowa study reported.

First IVF embryo research licenses issued in Australia

Australia’s first licences allowing research using excess human embryos were issued today by the Embryo Research Licensing Committee of the National Health and Medical Research Council, (The NHMRC Licensing Committee).

IVF improvements in United States

Since its introduction in the United States, assisted reproduction technology has helped allow women to conceive more than a million babies.

Fertility specialists find multiple birth rate declining

During the past decade in the United States, increasing attention has been paid to lowering the incidence of multiple gestations resulting from the use of assisted reproductive technology. To determine whether such efforts have been successful, we assessed national trends in embryo-transfer practice patterns and in outcomes after the use of assisted reproductive technology.

Protein kinase complex influences the outer layer of skin to control the eventual shape of the full-grown skeleton and skull

Continuing studies about an important regulatory protein kinase complex called I-kappa-B kinase (or IKK) have now shown that a subunit of IKK – IKK alpha – influences the outer layer of skin in developing mice to control the eventual shape of the full-grown skeleton and skull.

Zebrafish show effects of ionizing and UV radiation differ during embryo development

Adam Dicker, M.D., Ph.D., associate professor of radiation oncology at Jefferson Medical College of Thomas Jefferson University and Jefferson’s Kimmel Cancer Center in Philadelphia, Mary Frances McAleer, M.D., Ph.D., a resident in the Department of Radiation Oncology at Jefferson Medical College and their co-workers compared the effects on zebrafish embryos of two types of radiation – ionizing radiation, which is the kind given to patients for cancer treatment, and ultraviolet (UV) radiation, which comes naturally from the sun.

Research suggests protein released from lungs could initiate labour

A protein released from the lungs of a developing mouse fetus initiates a cascade of chemical events leading to the mother's initiation of labor, researchers at UT Southwestern Medical Center at Dallas have found.

Japanese study raises concerns for childhood health issues

The number of children suffering from mental disorders and health problems such as allergies and asthma has risen sharply over the past decade in this country. The United States and European countries are also facing the increasingly serious problems of premature births and childhood obesity, in addition to allergic reactions. Many experts say the rise in health problems involving children is related to the use of chemicals in our daily lives and the impact of medical treatment provided to the children's mothers.
