Discovery identifies non-DNA mechanism involved in transmitting paternal experience to offspring
It has long been understood that a parent's DNA is the principal determinant of health and disease in offspring. Yet inheritance via DNA is only part of the story; a father's lifestyle such as diet, being overweight and stress ...

Oocyte growth relies on physical phenomena that drive smaller cells to dump their contents into a larger cell
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.

Cryptic sex: How female and unisexual animals reproduce without males
Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm's DNA. I describe how this self-sexual ...

Some sperms poison their competitors
Competition among sperm cells is fierce—they all want to reach the egg cell first to fertilize it. A research team from Berlin now shows in mice that the ability of sperm to move progressively depends on the protein RAC1. ...

Keeping sperm cells on track
An essential component of every eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are antenna-like structures ...

Molecular 'barcode' helps decide which sperm will reach an egg
A protein called CatSper1 may act as a molecular 'barcode' that helps determine which sperm cells will make it to an egg and which are eliminated along the way.

Delivering proteins to testes could someday treat male infertility
According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, researchers reporting in ACS ...
