Frozen sperm taken by biopsy from testicles may help couples conceive through IVF

Frozen sperm taken by biopsy from testicles in men with no sperm in their semen is as effective as fresh sperm taken by biopsy in helping couples conceive through in vitro fertilization (IVF), according to a study at Washington University School of Medicine in St. Louis.

Trace substance in sugar improves muscle regeneration in mouse model with muscular dystrophy

A trace substance in caramelized sugar, when purified and given in appropriate doses, improves muscle regeneration in a mouse model of Duchenne muscular dystrophy. The findings are published today, Aug. 1, in the journal Skeletal Muscle.

Findings open new perspectives for research on proteins that control metastasis

In experiments on zebrafish, Freiburg researchers have demonstrated that the same proteins that lead to the formation of metastases in humans also cause the cells to migrate during embryonic development.

CLAMP: A newly discovered protein that regulates genes

They say a good man is hard to find. Were it not for a newly discovered protein, the X chromosome of a male fruit fly could never be found by a gene-regulating complex that male flies need to develop and survive. And that case is just one example of what the new finding means. More generally, the research provides biologists with a model of how proteins that govern gene transcription find their targets on chromosomes, a process that's essential to healthy cell function and sometimes implicated in disease.

NKX2-8 mutation in dogs may be a risk factor for human neural tube defects, say researchers

A gene related to neural tube defects in dogs has for the first time been identified by researchers at the University of California, Davis, and University of Iowa.

Obese fathers may pass their obesity to children and grandchildren

New research from the University of Adelaide shows that the sperm of obese fathers could increase the risk of both their children and their grandchildren to inherit obesity.

New theory challenges orthodox view that cancer develops in each host by mutational accidents

A new way to look at cancer -- by tracing its deep evolutionary roots to the dawn of multicellularity more than a billion years ago -- has been proposed by Paul Davies of Arizona State University's Beyond Center for Fundamental Concepts in Science in collaboration with Charles Lineweaver of the Australian National University.

Women feel positive about egg freezing

Egg freezing as insurance against age-related infertility is a growing trend in many countries. Women who bank oocytes for use at some time in the future hope to buy a little time in their search for a suitable partner.

Study shows female obesity may reduce receptivity of uterus to embryo implantation

An analysis of almost 10,000 first cycles of egg donation treatment at one of Europe's largest IVF centres shows that female obesity reduces the receptivity of the uterus to embryo implantation and thereby compromises reproductive outcome.

Multiple pregnancies conceived after IVF associated with increased breast cancer risk

Women who give birth to multiple babies following IVF treatment are at a higher risk of breast cancer than those giving birth to singletons or who remain childless. Dutch investigators from the Omega study group said the explanation may not be the multiple pregnancy per se but a maternal trait related to a higher implantation potential and to breast cancer itself.

Macrophages play essential role in production of progesterone hormone

New research from the University of Adelaide shows for the first time that immune cells known as macrophages are critical to fertility by creating a healthy hormone environment in the uterus.

New low-cost method of in-vitro fertilization may help infertile couples in developing countries

A new low-cost method of in-vitro fertilization developed at the University of Colorado Boulder that performed successfully in recent human clinical trials in Belgium may help thousands of infertile couples in developing countries.

Risk of implantation failure, lower yield of oocytes linked to higher levels of urinary phthalates

Phthalates are among a group of industrial chemicals shown in some studies to have adverse effects on reproductive health and development, particularly in the male. As such, they have been collectively defined as "endocrine disruptors", and proposed as one of several possible environmental exposures responsible for a decline in fertility.

Research shows gene regulatory sequences may have driven the evolution of human limbs

Thousands of sequences that control genes are active in the developing human limb and may have driven the evolution of the human hand and foot, a comparative genomics study led by Yale School of Medicine researchers has found.

Study on assisted reproduction published in Reproductive BioMedicine Online

Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced the publication of a recent retrospective study in Reproductive BioMedicine Online to better understand treatment considerations and outcomes for same-sex male couples and single men when using assisted reproduction treatment.

Scientists identify molecular signals that spur the formation of arteries

The ability to form blood vessels is one of evolution's crowning achievements, and something that separates vertebrates (animals with a backbone) from the rest of the animal kingdom.

Scientists discover network for molecular communication in human embryonic stem cells

Scientists at A*STAR's Genome Institute of Singapore (GIS) and the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin (Germany) have discovered a molecular network in human embryonic stem cells (hESCs) that integrates cell communication signals to keep the cell in its stem cell state.

Medical ethicists find no justification to support UK's legal ban on sex selection

As Europe's leading fertility specialists gather at a conference in London this weekend, a major new publication from leading medical ethicists finds no justification to support the UK's legal ban on sex selection before pregnancy for 'social' reasons.

Mixed results for acupuncture in improving IVF rates

Acupuncture, when used as a complementary or adjuvant therapy for in vitro fertilization (IVF), may be beneficial depending on the baseline pregnancy rates of a fertility clinic, according to research from the University of Maryland School of Medicine. The analysis from the University of Maryland Center for Integrative Medicine is published in the June 27 online edition of the journal Human Reproduction Update.

UCSF researchers find that vitamin C may help stem cells, in vitro fertilization

Vitamin C affects whether genes are switched on or off inside mouse stem cells, and may thereby play a previously unknown and fundamental role in helping to guide normal development in mice, humans and other animals, a scientific team led by UC San Francisco researchers has discovered.
