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.

CoQ10 shows promise in boosting female fertility by reviving aging eggs

Researchers reviewed evidence on Coenzyme Q10 (CoQ10) and found it may enhance mitochondrial function, improve oocyte quality, and counteract age-related fertility decline. The review highlights promising results from clinical, preclinical, and in vitro studies but calls for larger trials to confirm safety, dosing, and effectiveness.

CRISPR-GPT helps scientists to generate designs, analyze data and troubleshoot design flaws

Stanford Medicine researchers have developed an artificial intelligence tool to help scientists better plan gene-editing experiments.

Can cannabis use disrupt women’s fertility? New study finds strong evidence

Researchers found that THC, the psychoactive compound in cannabis, alters oocyte gene expression, spindle formation, and chromosome segregation, lowering embryo euploidy rates in IVF. This provides direct human evidence linking cannabis exposure to impaired female fertility outcomes.

Cornell researchers develop device to simplify fertility treatment

In the quest to address infertility, Cornell University researchers have developed a groundbreaking device that could simplify and automate oocyte cumulus removal, a critical step in assisted reproductive technologies.

New technique succeeds in studying embryo implantation outside the body

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while these technologies successfully create viable embryos, a little over half of all embryos are lost because they fail to implant into the uterus.
