Scientists investigate the role of the extracellular matrix in tissue growth

Growing from a single cell into a complex organism with specialized tissues and organs requires a complex and coordinated process.

Study finds increased rates of DNA mutations in mice pups conceived with IVF

Mice pups conceived with in vitro fertilization (IVF) in the lab have slightly increased rates of DNA errors, or mutations, compared to pups conceived naturally, a new study on artificial reproductive technologies suggests.

Terasaki Institute and Caltech join forces on groundbreaking embryo formation study

The Terasaki Institute for Biomedical Innovation (TIBI) is pleased to announce its collaboration with the California Institute of Technology (Caltech) on a newly awarded $2.8 million Discovery Stage Research (DISC0) grant from the California Institute for Regenerative Medicine (CIRM).

Hiiragi group and Prevedel group collaborate with Prospective Instruments to pioneer intravital multiphoton microscopy for early embryo research

Prof. Takashi Hiiragi (Hubrecht Institute), Dr. Robert Prevedel (European Molecular Biology Laboratory), and Dr. Lukas Krainer (Prospective Instruments) have launched an interdisciplinary collaboration to develop a novel intravital microscopy platform for studying mammalian embryo implantation.

Micro-RNA in sperm proves vital for human embryogenesis

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to the development of the embryo several days after conception. The findings, published in the journal Nature Communications, may in the long term contribute to better diagnosis and treatment of involuntary childlessness.

Scientists identify essential process that protects DNA integrity in reproductive cells

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects during egg formation.

Columbia researchers report first successful pregnancy using AI-guided sperm recovery method

Researchers at the Columbia University Fertility Center reported the first successful pregnancy using an AI-guided method they developed to recover sperm in men with azoospermia, in which ejaculate contains little or no sperm.

Discovering the role of lingual and buccal cells in tooth development

A novel study on the natural coordination of tooth development in time and space, led by Dr. Han-Sung Jung at the Yonsei University College of Dentistry, Korea, has discovered that "lingual" cells on the side of the tongue form the tooth, whereas those toward the cheek, called "buccal cells," form the bones and gums, guided by signaling molecules like WNT and BMP.

Study: Common test to assess viability of IVF embryos may be flawed

A test deployed in many fertility clinics to assess the viability of embryos for use in IVF is likely to overestimate the number of embryos with abnormalities, suggests a study published today.

Researchers achieve proof of concept for generating eggs from somatic cells

Researchers at Oregon Health & Science University have accomplished a unique proof of concept to treat infertility by turning skin cells into eggs capable of producing early human embryos.

Review reveals how paternal lifestyle shapes sperm epigenetics and offspring health

A new review in Clinical Epigenetics synthesises growing evidence that paternal lifestyle and environmental exposures such as diet, obesity, smoking, endocrine-disrupting chemicals, and stress alter sperm epigenetic marks (DNA methylation, histone retention, and small non-coding RNAs).

Cancer hijacks embryonic gene editors to fuel growth

Cancer cells are known to reawaken embryonic genes to grow. A new study reveals the disease also hijacks the proteins, or "editors", that control how those genes are read.

Lab-grown embryo models mimic natural formation of blood and heart cells

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the production of blood stem cells.

Lifestyle choices and hormonal imbalances can impact men's reproductive health

A new research paper was published in Volume 12 of Oncoscience on September 30, 2025, titled "Lifestyle and hormonal factors affecting semen quality and sperm DNA integrity: A cross-sectional study."

Harmful DNA changes in the sperm found to rise sharply with age

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm production, new research has revealed.

Clinical trial disproves claims that antioxidant supplement boosts male fertility

A large Dutch randomized clinical trial (SUMMER) found that a widely marketed antioxidant supplement (Impryl) did not improve ongoing pregnancy rates in men seeking fertility care. Instead, pregnancy success was significantly lower in the critical 4–6 month treatment window, raising safety concerns.

Metabolic activity found to control the tempo of embryo segmentation clock

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully.

Majority of parents disclose biological origins to their donor-conceived children

Four out of five parents tell their donor-conceived children about their biological origins, according to new research out of Waipapa Taumata Rau, University of Auckland.
