A January executive order by President Donald Trump designates people as female if they make the “large” reproductive cell (the egg) and male if they make the ...

In females, it is preferentially included in the egg. "The ability to hijack meiosis in the very different contexts of male germ cells and oocytes is remarkable," says Dr. Steve Perlman, a biologist ...

Some genes just don’t play fair.Researchers have uncovered a ‘selfish’ X chromosome in the fruit fly Drosophila testacea that ...

Expert Rev of Obstet Gynecol. 2008;3(4):555-563. The complex process of follicular and oocyte maturation can be affected by a number of tobacco constituents. Cadmium, polycyclic aromatic ...

This study presents useful findings regarding the role of formin-like 2 in mouse oocyte meiosis. Some of the data are supported by incomplete methodological details and analyses, and several ...

"A lot of studies have historically focused on one small aspect of why oocyte quality declines, which are meiosis and euploidy. However, a recent review of eleven thousand embryo transfers has ...

Here, we investigate the roles of Mcrs1 during female meiosis in mice. We demonstrate that Mcrs1 is a novel regulator of the meiotic G2/M transition and spindle assembly in mouse oocytes. Mcrs1 is ...

Thus, the microinjection of primary spermatocytes into oocytes may be a potential treatment for overcoming a form of nonobstructive azoospermia caused by meiotic failure. Mouse primary spermatocytes ...

Meiosis is a specialized cell cycle that requires sequential changes to the cell division machinery to facilitate changing functions. To define the mechanisms that ...

In this study, we discovered that depletion of FKBP25 protein has an adverse effect on the meiosis of mouse oocytes, especially disrupting the assembly of meiotic apparatus. Meanwhile, We found that ...
