Periconceptional maternal smoking associated with delay in embryonic development

Smoking by mothers during the period immediately before and after conception is linked to a delay in embryonic development, smaller foetuses at the time of the 20-week ultrasound scan, and lower birth weight.

Common infertility treatment linked to increased risk for vascular and pregnancy-related complications

Women who conceive with assisted reproductive technology (infertility treatment) may be at increased risk for vascular and pregnancy-related complications, according to new research published today in a special Go Red for Women issue of the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Zebrafish model reveals how early embryo cells begin to independently produce proteins

It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs.

COVID-19 vaccination does not affect fertility outcomes in patients undergoing in-vitro fertilization

Vaccination against COVID-19 did not affect fertility outcomes in patients undergoing in-vitro fertilization (IVF), a new study has found.

Study reveals an increasing proportion of women giving birth at 40+

An increasing proportion of women aged 40 and over in Sweden and Denmark are giving birth. Nevertheless, over a recent 10-year period, the need for assisted reproduction for women over 40 in Scandinavia has doubled, a study led by University of Gothenburg researchers shows.

Children conceived with assisted reproductive techniques are not at risk of poor psychiatric health

Use of assisted reproductive techniques (ART) does not lead to poorer mental health in children across adolescence and young adulthood, according to a large observational study led by researchers at Karolinska Institutet in Sweden.

Cells with oncogenic mutations overtake human tissue with age, research shows

It's worth noting, in light of recently published research, that a majority of people won't be diagnosed with cancer in their lifetimes. According to the National Cancer Institute, about 40% of people will, which means 60% won't.

Research offers a phylogenetic and ontogenetic overview of the primitive streak

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of Virginia Health System, USA) offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications of embryonic stem cell-based models of early mammalian embryogenesis on the function of this structure.

Researchers shed light on an important stage of early human embryogenesis for the first time

Scientists have shed light on an important stage of early embryonic development that has never been fully mapped out in humans before.

Using the contraceptive pill to reduce risk of type-2 diabetes in women with PCOS

In this interview, News-Medical speaks to Professor Weibke Arlt about her recent research into how the contraceptive pill affects type 2 diabetes in women with PCOS.

UGA study makes breakthrough for treatment of male infertility

With global rates of male infertility continuing to rise, a new study in spermatogonial stem cell research led by researchers at the University of Georgia provides hope for future clinical therapies.

Mothers pass on the legacy of stress exposure to future generations

A mother's response to stress can even influence her grandchildren. Biologists at the University of Iowa found that roundworm mothers subjected to heat stress passed, under certain conditions and through modifications to their genes, the legacy of that stress exposure not only to their offspring but even to their offspring's children.

Using genetic screening for selecting the 'best' embryo in IVF

Each year, tens of thousands of babies are born in the United States as the result of IVF (in vitro fertilization) – where several eggs are fertilized outside the mother's body and then an embryo is selected for transfer into her womb.

Researcher calls for a broader and more inclusive definition of infertility

Academy Research Fellow Jukka Kekäläinen from the University of Eastern Finland calls for a broader and more inclusive definition of infertility in a recent opinion piece published in the journal Human Reproduction last week.

Collins’ skillful piloting helped NIH steer clear of political minefields

It's remarkable that the reputation of the National Institutes of Health has remained mostly intact through the covid-19 pandemic, even as other federal science agencies, including the Food and Drug Administration and Centers for Disease Control and Prevention, have come under partisan fire.

Scientists create a novel cell model for understanding human development

The earliest moments of human development—between the time of fertilization and when the embryo implants in the womb—have remained opaque to scientists.

Optimized strategy for generating male germ-cells from mouse pluripotent stem cells

For species that rely on sexual reproduction, including mice and men, offspring can only happen if sperm from the male fertilize eggs from the female.

Growing wheat varieties with biological nitrification inhibition trait could increase yields

An international collaboration has discovered and transferred to elite wheat varieties a wild-grass chromosome segment that causes roots to secrete natural inhibitors of nitrification, offering a way to dial back on heavy fertilizer use for wheat and to reduce the crop's nitrogen leakage into waterways and air, while maintaining or raising its productivity and grain quality, says a new report in the Proceedings of the National Academy of Sciences of the United States of America.
