In a new study published in the journal Nature, researchers in Japan report that activating just eight genes for producing gene-controlling proteins is enough to convert mouse stem cells directly into ...

Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles. Within these ...

A major new study suggests that age-related changes in the uterus may contribute to poorer pregnancy outcomes, with women ...

Oocyte quality assessment constitutes a critical determinant of success in assisted reproductive technology, influencing fertilisation rates, embryo development and clinical pregnancy outcomes.

A team of reproductive biologists at Nanjing Agricultural University has found that spermidine, a polyamine metabolite, helps oocytes clear away damaged mitochondria in mice, thereby improving ...

Communication between oocytes and granulosa cells is essential for oocyte formation, dormancy, reawakening, and maturation. Researchers have demonstrated that a protein complex called the exocyst ...

A core set of eight proteins can transform stem cells from mice into cells that look a lot like immature egg cells called oocytes. The egglike cells could not undergo meiosis to cut the total ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

Of all the available means of fertility preservation, 1 oocyte cryopreservation by means of vitrification (very rapid freezing) provides the highest yield, not only for women with benign diseases or ...
