Ascidian fertilization has long served as a tractable model for understanding fundamental mechanisms of gamete recognition, binding and fusion in chordates. Spermatozoa released into seawater are ...

Researchers at ETH Zurich recently developed highly realistic simulations of the proteins on sperm and egg cells coupling together before they fuse. These findings enabled the research team to solve ...

After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work ...

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 ...

A research team from the Department of Obstetrics and Gynecology at the University of Hong Kong's LKS Faculty of Medicine (HKUMed) has developed the world's first artificial intelligence (AI) model ...

Some men produce too many sperms. That little-mentioned fact was the focus of my previous blog post. (See Why Too Many Sperms Spoil the Egg, posted on August 11, 2017.) With too many sperms, an ...

This short film uses CGI footage to help give a visual description of the process of human fertilisation, following the ...

How a sperm and an egg fuse together has long been a mystery. New research by scientists in Austria provides tantalizing clues, showing fertilization works like a lock and key across the animal ...
