With the help of the ESRF, researchers from Karolinska Institutet (Sweden) have discovered the reproductive mechanism that permanently blocks polyspermy — a pathologic condition that arises when more ...
AMHERST, Mass. - Current molecular biochemistry, microscopy and genetic techniques have become so powerful that scientists can now make mechanistic discoveries - supported by multiple lines of ...
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 ...
Countless sperm may surround an egg at one time, yet only one must be allowed to fertilize it. In fact, an egg must undergo a rapid and complex series of changes to prevent entry by more than one ...
Zinc flux during fertilization prevents polyspermy and improves the quality of embryo Zinc is released after fertilization helps in zona pellucida hardening Zinc spark is a calcium coordinated event ...

Molecular biologists have used powerful new molecular biochemistry, microscopy and genetic techniques to solve, in unprecedented detail, the mechanisms of how flowering plants avoid polyspermy.
Infertility affects around 15% of couples worldwide, according to the World Health Organization (WHO). Some cases of infertility are associated with mutations in the genes that are responsible for egg ...
