Human bodies have to be built from a single egg cell that's fertilized by a sperm cell. Many rounds of cell division occur as the body is developing, and it seems that there are plenty of chances for ...

Who hasn't seen it before: the view through the microscope in which a sperm penetrates an egg cell and fertilizes it. This fundamental step in procreation happens dynamically and seemingly without ...

Using a newly developed method researchers at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) have been able to shed light on the complexity of genome ...

Researchers at Oregon Health & Science University (OHSU) have developed a remarkable new way for making human body cells behave like egg cells—a technique that could change the course of the future of ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

For some couples, even in vitro fertilization (IVF) cannot fulfill the desire for a biological child. Women who have undergone cancer treatment, those whose egg reserves have declined with age, and ...

Explore the intricate relationship between ovarian reserve, egg quality, and reproductive aging. Discover how mitochondrial ...

Using Google’s AlphaFold, researchers identified the bundle of three sperm proteins that seem to make sexual reproduction possible. By Elizabeth Preston They’re the original odd couple: One is massive ...

Early lab work shows reprogrammed skin cells can yield embryos, hinting at future infertility solutions but raising safety questions that demand more study. Infertility affects millions of people ...

MUCH of my time as a biologist has been spent looking through a microscope at the beginnings of individual lives, partly in an effort to understand a little of how animals develop from eggs, partly ...
