Trump wants Americans to make more babies. Critics say his policies won’t help raise them.

Maddy Olcott plans to start a career once she graduates from college. But the junior at the State University of New York-Purchase College is so far not planning to start a family — even with the Trump administration dangling inducements like thousand-dollar "baby bonuses" or cheaper infertility drugs.

WHO releases first-ever global guideline for prevention, diagnosis and treatment of infertility

The World Health Organization (WHO) today called on countries to make fertility care safer, fairer and more affordable for all in its first-ever global guideline for the prevention, diagnosis and treatment of infertility.

Study uncovers role of mechanical forces in human gastrulation

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear.

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.

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.

17 Oct 2025

Study uncovers key protein complex controlling sperm motility and male fertility

Infertility affects about one in six couples, and male factors account for roughly half of all cases-often because sperm don't swim well.

13 Oct 2025

New insights into sperm metabolism could transform infertility treatments

Michigan State University scientists have pinpointed the molecular "switch" that supercharges sperm for their final sprint to an egg - a breakthrough that could reshape infertility treatments and pave the way for safe, nonhormonal male contraceptives.

10 Oct 2025

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.

Paternal exercise enhances offspring endurance through sperm microRNAs

In a recent study published in Cell Metabolism, a collaborative research team led by Chen-Yu Zhang, Xi Chen, and Di-Jun Chen from Nanjing University, together with Tao Zhang from Nanjing Medical University, reported groundbreaking findings in their paper entitled "Paternal exercise confers endurance capacity to offspring through sperm microRNAs."

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.

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.

5 Sep 2025

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.

2 Sep 2025

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.

Adjusting fertility drug timing boosts ovulation success in rat models

Researchers at Osaka Metropolitan University have found that changing the timing of fertility drugs to match the follicle maturity period significantly increases the number of ovulated oocytes-the cells that develop into eggs-during artificial fertilization, even in rats that typically produce few oocytes.

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.
