Forget the battle between the sexes. There’s a tinier battle raging within the sexes — at the genetic level. In some species’ sperm, X and Y chromosomes wrestle for dominance, each trying to improve ...

Researchers are delving into the molecular-level details of sperm formation, with a particular focus on how abnormalities in this process might lead to male-factor infertility. Sperm play a critical ...

Sperm play a critical role in the creation of new life, delivering essentially half of the genetic material required. The success of this process relies on the generation of a developmentally ...

The chromosomes of sperm cells are tightly packaged into a complex of DNA and protamines. Converting the chromatin from a nucleohistone to a nucleoprotamine structure may serve both biophysical and ...

Investigation of sperm formation and its molecular intricacies reveals a potential connection between infertility and alterations in sperm amino acids. Sperm chromatin structure and reproductive ...

One of the most remarkable chromatin remodelling processes occurs during spermiogenesis, the post-meiotic phase of sperm development during which histones are replaced with sperm-specific protamines ...

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University and colleagues have achieved a breakthrough in understanding sperm DNA packaging. Using high-speed atomic force microscopy ...

Sperm play a critical role in the creation of new life, delivering essentially half of the genetic material required. The success of this process relies on the generation of a developmentally ...
