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.

Infertility and obesity go together for some women

An Australian scientist says she has discovered scientific evidence that obesity is a key factor in infertility because of how it affects a woman's eggs.

Bacterial toxins and perforins have a common ancestor

Human immune proteins crucial for fighting cancer, viruses and bacterial infections belong to an ancient and lethal toxin family previously only found in bacteria, Australian researchers have found.

Effects of obesity on egg and infertility discovered

A researcher at the University of Adelaide, Australia, has discovered scientific evidence that obesity is a key factor in infertility – because of how it affects women's eggs.

Abortion pill does not spoil later pregnancies

According to the latest research the abortion pill poses no apparent risk to a woman who later decides to have a child.

Oestrogen research points to new class of analgesic drugs

Oestrogen plays an important role in determining how sensitive a person is to pain, and the oestrogen receptor known as ER-beta is particularly significant in this context.

New research may lead to future gene therapies for patients with sickle cell anemia and beta-thalassemia

Virginia Commonwealth University researchers studying hemoglobin genes, mutations of which play a role in genetic blood disorders like sickle cell anemia and beta-thalassemia, have identified two proteins that are responsible for regulating overlapping groups of genes during the development of red blood cells.

Discredited Korean embryonic stem cells' true origins revealed

A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells.

New WHO report on environmental hazards and child health

The World Health Organisation (WHO) says millions of children die each year because of environmental hazards and one in five children in the poorest parts of the world will not reach their sixth birthday, mainly because of environment-related diseases.

Sperm freezing for young male cancer patients

A recent study at Hamilton Health Sciences proves that sperm freezing and banking is an effective way to preserve fertility in adolescents and young adult (AYA) males with cancer.

Study reveals surge in male-factor infertility technique

A national study reveals that the use of intracytoplasmic sperm injection or ICSI -- an assisted reproductive technology used to treat male-factor infertility -- has increased dramatically in the United States since 1995, while the proportion of patients receiving treatment for male-factor infertility has remained stable.

Study shows that folic acid added to flours lowers incidence of congenital neural tube deformation

Dr. Philippe De Wals of Universit' Laval's Department of Social and Preventive Medicine today publishes a study clearly indicating that the addition of folic acid to flours has led to a 46% drop in the incidence of congenital neural tube deformation (mainly anencephaly and spina bifida) in Canada. Such deformations either result in the child's death or in major health problems, including physical and learning disabilities.

New data about the laws governing embryo development in organisms

Research aimed at understanding the mechanisms underlying embryo development has taken a step forward thanks to collaborative work between biologists specialized in the study of the fruit fly (Drosophila melanogaster) and scientists specialized in the design of mathematical models that simulate the functioning of biological systems.

Rapid evolution of defense genes in plants may produce hybrid incompatibility

One of the basic tenets of evolution is speciation in which populations of the same species become so genetically and morphologically variable that they can be classified as two different species.

New insight into neural stem cells

Scientists have discovered that adult neural stem cells, which exist in the brain throughout life, are not a single, homogeneous group.

Risk-taking in infertility treatment correlates with women's negative moods

A study of women's moods during IVF has found a strong relationship between negative mood and multiple embryo transfer, a scientist told the 23rd annual conference of the European Society of Human Reproduction and Embryology (Tuesday 3 July).

Promising new therapy for protecting the fertility of women with cancer

A promising new therapy for protecting the fertility of women with cancer and auto-immune diseases such as lupus was revealed at the 23rd annual conference of the European Society of Human Reproduction and Embryology.

Men physcologically affected by fertility problems as much as women

Although most psychosocial research into infertility is centred round the unhappiness it causes women, men suffer just as much, a scientist will tell the 23rd annual conference of the European Society of Human Reproduction and Embryology today (Wednesday 4 July).

Artificially replicating the male genome may help infertile men

Artificially replicating the male genome could help men with very low sperm counts become fathers, a scientist told the 23rd annual conference of the European Society of Human Reproduction and Embryology.

Complex assisted reproduction procedures more likely to lead to umbilical cord abnormality

The more complex the assisted reproduction procedure, the more likely the umbilical cord develops in an atypical place or have other abnormalities, a scientist told the 23rd annual conference of the European Society of Human Reproduction and Embryology.
