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 ...

During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. A central role is played by certain proteins around which the DNA thread is ...

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 ...

The alternative text for this image may have been generated using AI. We assessed chromatin integrity in intact sperm or sperm nuclei using fluorescence microscopy after treatment with methanol/acetic ...

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 ...
