Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable sperm, they found. A team at the RIKEN Center for Biosystems Dynamics Research ...

Researchers have identified an enzyme essential for the process of male meiosis, the type of cell division that produces sperm. The protein, SKP1, controls one of the key transitions in meiosis.

Researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This ...

They say opposites attract, and somehow even the wildly different X and Y chromosomes are able to pair up during sperm formation. New research shows how complex that process is, and it pinpoints a ...

While some of our body's cells divide in a matter of hours, the process of making sperm, meiosis, alone takes about 14 days from start to finish. And fully six of those days are spent in the stage ...
