Many women freeze their eggs to increase their chances of having children later — but that's not always a possibility. (Photo: Getty; designed by Quinn Lemmers) Ahead, women whose frozen eggs didn't ...

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 ...

Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm formation. Sometimes the best way to understand a biological process is to ...

Artificial ovaries are on the horizon after scientists created the first cellular-level map of human egg formation. The University of Michigan used five donated ovaries to carry out state-of-the-art ...

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 ...
