Using the power of single-cell analysis, researchers have assessed the effects of age on egg cells (oocytes) in mice, particularly looking to identify genomic and epigenetic factors that relate to ...

Recently published work from Carnegie's Allan Spradling and Wanbao Niu revealed in unprecedented detail the genetic instructions immature egg cells go through step by step as they mature into ...

This could be egg-cellent news for women struggling with infertility. A research team from Japan says it has developed a new egg maturation technique that may improve in vitro fertilization (IVF) ...

Female mammals are born with all the egg cells they will ever have in their ovaries. Some of these cells therefore live for a long time – and must remain functional throughout this period. Experiments ...

It may soon be possible to coax human skin cells into becoming functional eggs and sperm using a technique known as "in vitro gametogenesis." This involves the creation (genesis) of eggs and sperm ...

One of the immutable truths about being alive is that we age. This happens at every level, down to our cells. When they divide, our cells copy our DNA into each new cell. But as the weeks, months, and ...

The ticking of the biological clock is especially loud in the ovaries — the organs that store and release a woman’s eggs. From age 25 to 40, a woman’s chance of conceiving each month decreases ...
