Primordial germ cells, which emerge around day 16 in early human embryos, develop to form oogonia so that eventually, the number of oocytes that are present in an adult female is fixed at birth. After ...

The accumulation of misfolded or damaged proteins in long-lived, non-dividing cells like neurons are linked to neurodegenerative diseases like Alzheimer's. A study now finds that the build-up of these ...

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 ...

Extracellular vesicles have been engineered as enhanced drug vehicles, and have emerged as therapeutic agents showing promising results across various pathological conditions. However, they also play ...

CReATe Fertility Center in Toronto reports that tetrahydrocannabinol (THC) reaches the ovarian follicle, aligns with higher oocyte maturation, and associates with lower embryo euploid rates in IVF, ...

Oocytes are immature egg cells that develop in almost all female mammals before birth. The propagation of future generations depends on this finite reserve of cells surviving for many years without ...

The accurate distribution of chromosomes in an oocyte is essential for the correct transmission of genetic information to the next generation. Now, researchers from Kyushu University have demonstrated ...

Human oocytes can last for up to 50 years—and a newly discovered metabolic pathway is key to this longevity. By Lauren J. Young Published Jul 22, 2022 2:45 PM EDT Get the Popular Science daily ...

Declining female fertility is a health issue that has received broad global attention. Oocyte quality is the key limiting factor of female fertility, and factors affecting oocyte quality involve the ...
