Paternal sperm epigenetics may help explain early pregnancy loss

When a pregnancy ends early and unexplained, the search for answers usually begins with the mother. Lacey Luense, Ph.D., wants to know what the father's sperm might have to do with it.

Cellular glue protein found to help clear away dead cells

A protein which sticks cells and tissues together has been found to have a surprising second job: helping cells which are packed into a continuous sealed layer, also known as epithelial cells, engulf nearby dead cells.

Study reveals public willingness to select embryos using traits when given choices

A study of more than 2,000 people in the United States and China finds that the line between medical and non-medical traits, which underpins the rules on embryo testing in most countries, does not match the preferences of the public.

Book reframes pregnancy loss as a natural trial-and-error process

According to a new book from University of Illinois Urbana-Champaign anthropology professor Kate Clancy, pregnancy is necessarily fraught, involving a series of tests of egg, embryo and reproductive system viability, with potential losses at every stage.

Experts call for better trials as IVF preparation techniques show unproven results

Preparation techniques used before embryo transfer, considered the most critical step in the IVF process, show no proven effect on pregnancy rates and remain inconclusive due to limited or low-quality data, a new Cochrane review finds.

Malaria infection causes permanent damage to the spleen immune cells

Macrophages formed in the bone marrow can only assume the function of embryonal phagocytes, or "scavenger cells," to a certain degree according to a study by the University of Bonn and the Peter Doherty Institute for Infection and Immunity at the University of Melbourne.

New research explains how embryos establish germline cell boundaries

Every embryo of an organism that reproduces sexually faces an early and consequential decision: which of its cell lineages will make up the mortal body, and which will become the germline, the lineage that eventually makes eggs or sperm and carries genetic information to the next generation.

Air pollution may impact genes involved in sperm development

New research presented today at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests that exposure to air pollution may impact genes associated with sperm development, raising new questions about male fertility, pregnancy outcomes and offspring health.

Uterine aging may reduce donor egg pregnancy success after 49

A major new study suggests that age-related changes in the uterus may contribute to poorer pregnancy outcomes, with women aged 49 and over experiencing lower live birth rates and higher miscarriage risk despite donor-oocyte treatment.
