Maternal age drives embryo arrest independently of chromosomal errors

A new research paper was published in Volume 17, Issue 10 of Aging-US on October 10, 2025, titled "Developmental arrest rate of an embryo cohort correlates with advancing reproductive age, but not with the aneuploidy rate of the resulting blastocysts in good prognosis patients: a study of 25,974 embryos."

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.

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.

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.

Four distinct subgroups of PCOS open up for more tailored treatments

Four distinct subgroups of polycystic ovary syndrome (PCOS) have been identified in an international study published in Nature Medicine by researchers from Karolinska Institutet, among others.

KFF Health News' 'What the Health?': Nutrition programs face their own shutdown

Health programs are feeling the pinch of the ongoing government shutdown. Funding for the Supplemental Nutrition Assistance Program, or SNAP, and the food program for women, infants, and children, WIC, is likely to run out in November, and cuts at the Centers for Disease Control and Prevention are keeping the agency from carrying out some of its primary public health functions.

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.

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.

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.

KFF Health News' 'What the Health?': Countdown to government shutdown

Oct. 1 is the start of the next fiscal year, and unless Congress reaches agreement on continued spending, big parts of the government could shut down that day.

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.

Male and female bovine embryos show distinct development paths

Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization.

Genetic testing of IVF-created embryos could help more women over 35 have a baby sooner

Genetic testing of IVF-created embryos could help more women over 35 have a baby in less time, a clinical trial by researchers from King's College London, King's College Hospital, and King's Fertility has found.

KFF Health News' 'What the Health?': Kennedy cancels vaccine funding

Health and Human Services Secretary Robert F. Kennedy Jr.'s announcement that the federal government will cancel nearly $500 million in mRNA research funding is unnerving not only for those who develop vaccines, but also for public health experts who see the technology behind the first covid-19 shots as the nation's best hope to combat a future pandemic.

New study links surrogacy to higher risk of mental illness

People who are gestational carriers (or "surrogates") appear more likely to be diagnosed with a new mental illness during and after pregnancy, according to new research from ICES, McGill University, and the Research Institute of the McGill University Health Centre.

Sperm RNA profiles could identify the best embryos for IVF

Findings on sperm RNA suggest new biomarkers for IVF success, potentially improving embryo selection and reducing cycles needed for desired fertility outcomes.

Human eggs use a minimalist strategy to stay healthy for decades

Human eggs are some of the most patient cells in the body, lying dormant for decades until needed. A study published today in The EMBO Journal shows that the cells deliberately slow the activity of their internal waste disposal systems as they mature, most likely an evolutionary design which keeps metabolism low and damage at bay.

New data confirms efficacy of mitochondrial donation in preventing disease

The UK's pioneering licensed IVF technique to reduce the risk of mitochondrial diseases carried out in Newcastle has seen eight babies born, published research shows.

FEMI helps predict IVF outcomes with greater accuracy

FEMI, an AI model for IVF, uses 18 million images to improve embryo assessment, offering a non-invasive, cost-effective solution for better success rates.
