Researchers have found that a carefully orchestrated act of X-chromosome 'yoyo' predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating ...

Since December 2022, the nationwide control policy on the COVID-19 epidemic has been changed in China. Fertility and in vitro fertilization (IVF) centers are receiving increasing numbers of infected ...

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 ...

A multi-institutional team of ovarian biologists and other reproductive specialists reports that putting an oocyte from an older mouse into the follicle of a young mouse can rejuvenate the oocyte, ...

When the female germline develops, oocyte growth is accompanied by many changes in gene expression, however, the regulatory networks that control this process have not been determined. Now, a group of ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...

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 ...

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 ...

Advances in reproductive science suggest that fertility is shaped not only by the number of eggs remaining in the ovaries, but also by the biological quality and cellular health of those eggs.
