A highly detailed study of how the roundworm C. elegans forms oocytes suggests that the egg-making process leads to the formation and subsequent destruction of cells with an extra nucleus, but that ...

The process of egg formation in fruit flies relies on physical phenomena analogous to the exchange of gases between balloons of different sizes, according to a new study by biologists and ...

Studying sex from just the male perspective misses half the experience. But much of what we know about the origins of reproductive cells comes from looking at sperm and egg formation separately—or ...

Why does making new egg cells require so much cell death? During egg production, roundworms create and then destroy oocytes with two nuclei Date: July 19, 2018 Source: PLOS Summary: A highly detailed ...

Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells. There's a reason ...
