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.

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.

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.

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.

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.

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.

Australian researchers uncover new target for next-generation malaria vaccines

Australian researchers have visualized a key protein complex in malaria parasites for the first time, uncovering a new target for next-generation vaccines that could help stop the disease from spreading.

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.

Zebrafish reveal how two genes independently drive sensory organ regeneration

Researchers identified that two cyclin D genes, ccndx and ccnd2a, independently regulate distinct stem and progenitor cell populations during zebrafish sensory organ regeneration. The findings reveal that regeneration can proceed via alternative pathways even when one gene is disrupted, providing new insight into tissue repair mechanisms.
